3 Overview

The VP-8x8TP is a high performance 8x8 computer graphics video and audio matrix switcher for high resolution video and stereo audio signals. The VP-8x8TP is HDTV compatible and lets you route any combination of inputs and outputs over TP (Twisted Pair) cable to compatible TP receivers.

In particular, the VP-8x8TP 8x8 UXGA/Audio Matrix Switcher features:

• Kramer's innovative integrated sync processing Kr-isp® technology that lets you achieve a sharp, stable image when the sync level is too low, by restoring the sync signal waveform
  • Resolution up to UXGA (1600 x 1200), 1080p
• Support for component video with suitable breakout cables ^1
• 16 preset memory locations for quick access to common video and audio configurations and audio gain status for each output
• Automatic detection of the connected input signals (the respective button lights)
• A delayed switching mode (ranging from 0 to 3.5sec^2 ) for clean transitions (seamless switching) when switching between non-genlocked sources
  • DC-coupled video inputs and outputs
  • Audio-follow-video and breakaway options
• Eight stereo unbalanced audio input signals on 3.5mm mini jacks
  • Eight RJ-45 STP/UTP output connectors
• Over 100m (330ft) transmission range between the switcher and the TP receiver
  • Audio level control buttons for adjusting the signal level of each input
• Measurement and indication of the audio level for each input and output, in relative dB
• A TAKE button, which allows you to place multiple switches in a queue and then activate them simultaneously with one touch of this button
• A LOCK button to prevent tampering with the front panel

The VP-8x8TP can be controlled using the front panel buttons, or remotely via:

• RS-485 or RS-232 serial commands (using Kramer 2000 and 3000 Protocols) transmitted by a touch screen system, PC, or other serial controller
• The Kramer infrared remote control transmitter or infrared remote extension cable transmitter (optional)
  • A Web browser over Ethernet

The VP-8x8TP is dependable, rugged, and fits into one vertical space (1U) of a standard 19" professional rack.

To achieve the best performance:

• Use only good quality connection cables ^1 to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables)
• Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your Kramer VP-8x8TP away from moisture, excessive sunlight and dust

3.1 Terminology Used in this User Manual

Table 1 defines some terms that are used in this user manual.
Table 1: Terminology Used in this Manual

Term	Definition
802.3	The standard specification for Ethernet that is maintained by the Institute of Electrical and Electronics Engineers (IEEE).
Dynamic Host Configuration Protocol (DHCP)	Allows the network administrator to distribute IP addresses from a central point and automatically send a new IP address when an Ethernet point is plugged into a different network location.
Gateway	A network position serving as an entry to another network. On the Internet, a node or stopping point can be either a gateway node or a host (end-point) node.
IP Address	A 32-binary digit number that identifies each sender or receiver (within a network via a particular server or workstation) of data (HTML pages or e-mails) that is sent in packets across the Internet. Every device connected to an IP network must have a unique IP address. This address is used to reference the specific unit.
Local Area Network (LAN)	Computers sharing a common communications line or wireless link, which often share a server within a defined geographic area.
Media Access Control (MAC) Address	A computer's unique hardware number (or address) in a LAN or other network. On an Ethernet LAN, the (MAC) address is identical to the Ethernet address.
Transmission Control Protocol/Internet Protocol (TCP/IP)	The basic communication language or protocol of the Internet that breaks the message into appropriately sized packets for the network, and can be used as a communications protocol in an intranet or an extranet.

3.2 Shielded Twisted Pair and Unshielded Twisted Pair

We recommend that you use Shielded Twisted Pair (STP) cable. There are different grades of STP cable available, and we advise you to use the best quality STP cable that you can afford. Our non-skew-free cable, Kramer BC-STP is intended for digital signals and for analog signals where skewing is not an issue. For cases where skewing occurs, our UTP skew-free cable, Kramer BC-XTP, may be used. Bear in mind, though, that we advise using STP cables where possible, since the compliance to electromagnetic interference has been tested using STP cables.

Although Unshielded Twisted Pair (UTP) cable might be preferred for long range applications, UTP cable should be installed as far as possible from electric cables, motors, and so on, as these devices tend to create electromagnetic interference. However, since the use of UTP cable might not conform to electromagnetic standards, Kramer does not commit to meeting the standard with UTP cable.

3.3 Defining the EDID

The Extended Display Identification Data (EDID ^1 ) is a data-structure, provided by a display, to describe its capabilities to a graphics card (that is connected to the display's source). The EDID enables the PC or laptop to “know” what kind of monitor is connected to the output. The EDID includes the manufacturer's name, the product type, the timing data supported by the display, the display size, luminance data and (for digital displays only) the pixel mapping data.

3.4 The Power Connect™ Feature in the VP-8x8TP

The Power Connect feature applies as long as the cable can carry power. This feature is available when using STP cable and the distance does not exceed 50m (164ft) on standard CAT 5 cable. For longer distances, heavy gauge cable should be used (CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances). For units which are connected via RJ-45 connectors, make sure that the shield of the STP cable is connected to the metal casing of the connectors on both ends of the cable. For units which are connected via terminal block connectors, the shield of the STP cable must be connected to a ground terminal on the units at both ends (use the ground terminal of the power supply connection if necessary).

For a CAT 5 cable exceeding a distance of 50m, separate power supplies should be connected to the receivers simultaneously.

Note: The transmitter can supply power to the receiver but not visa versa.

5 Installing the VP-8x8TP in a Rack

This section describes what to do before installing in a rack and how to rack mount the VP-8x8TP.

Before installing in a rack, be sure that the environment is within the recommended range:

OPERATING TEMPERATURE:	0° to +55°C (32° to 131°F)
STORAGE TEMPERATURE:	-45° to +72°C (-49° to 162°F)
HUMIDITY:	10% to 90%, RHL non-condensing

CAUTION!

When installing on a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.
2. Once rack mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

Technical line drawing of a mechanical bracket assembly with bolts and mounting holes (no text or symbols)

1. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note:

By default, the VP-8x8TP is set to Kramer's Protocol 3000, but it is also compatible with Protocol 2000.

16.1 Switching Protocols

You can switch protocols either via the front panel buttons (see Section 16.1.1) or by sending protocol commands (see Section 16.1.2).

16.1.1 Switching Protocols via the Front Panel Buttons

To switch from Protocol 3000 to Protocol 2000, press and hold ^1 the OUT 1 and OUT 2 buttons for a few seconds.

To switch from Protocol 2000 to Protocol 3000, press and hold the OUT 1 and OUT 3 buttons for a few seconds.

16.1.2 Switching Protocols via Protocol Commands

To switch from Protocol 3000 to Protocol 2000, send the following command:

- #P2000

To switch from Protocol 2000 to Protocol 3000, send the following command:

- 0x38, 0x80, 0x83, 0x81

The Windows®-based Kramer control software ^2 operates with Protocol 2000. If the VP-8x8TP is set to Protocol 3000, it is automatically switched to Protocol 2000.

16.2 Kramer Protocol 3000

This RS-232/RS-485 communication protocol lets you control the machine from any standard terminal software (for example, Windows ^® HyperTerminal) with default settings of 115200 baud data rate, no parity, 8 data bits, and 1 stop bit.

16.2.1 Protocol 3000 Syntax

Host message format:

Start	Address (optional)	Body	Delimiter
#	Destination_id@message		CR

Simple command (commands string with only one command without addressing):

start	body	delimiter
# Command SP	Parameter_1,Parameter_2,...	CR

Commands string (formal syntax with commands concatenation and addressing):

# Address@ Command_1 Parameter1_1,Parameter1_2,... |Command_2 Parameter2_1,Parameter2_2,... |Command_3 Parameter3_1,Parameter3_2,... |...CR

Device message format:

Start	Address (optional)	Body	Delimiter
~	Sender_id@	message	CR LF

Device long response (Echoing command):

Start Address(optional)	Body Delimiter
~ Sender_id@	command SP [param1 ,param2 ...] result	CR LF

$$ \boxed {\mathbf {C R}} = \text { Carriage return (ASCII 13 = 0x0D) } $$

$$ \boxed {\mathbf {L F}} = \text { Line feed(ASCII10 = 0x0A)} $$

$$ \boxed {\mathbf {S P}} = \text { Space (ASCII 32 = 0x20) } $$

16.2.2 Command Parts Details

Command:

Sequence of ASCII letters ('A'-Z', 'a'-z' and '-'').

Command will separate from parameters with at least single space.

Parameters:

Sequence of Alfa-Numeric ASCII chars ('0'-9', 'A'-Z', 'a'-z' and some special chars for specific commands), parameters will be separated by commas.

Message string:

Every command must to be entered as part of message string that begin with message starting char and end with message closing char, note that string can contain more then one command separated by pipe (") char.

Message starting char:

'#' for host command\query.

'\~' for machine response.

Device address (Optional, for Knet):

Knet Device ID follow by '@' char.

Query sign = '?' , will follow after some commands to define query request.

Message closing char =

Host messages - Carriage Return (ASCII 13), will be referred to by CR in this document.

Machine messages - Carriage Return (ASCII 13) + Line-Feed (ASCII 10), will be referred to by CRLF

Spaces between parameters or command parts will be ignored.

Commands chain separator char:

When message string contains more than one command, commands will be separated by pipe ( "|").

Commands entering:

If terminal software used to connect over serial \ ethernet \ USB port, that possible to directly enter all commands characters (CR will be entered by Enter key, that key send also LF but this char will be ignored by commands parser).

Sending commands from some controllers (like Crestron) require coding some characters in special form (like \X##). Anyway, there is a way to enter all ASCII characters, so it is possible to send all commands also from controller.

(Similar way can use for URL \ Telnet support that maybe will be added in future).

Commands forms:

Some commands have short name syntax beside the full name to allow faster typing, response is always in long syntax.

Commands chaining:

It is possible to enter multiple commands in same string by "|' char (pipe).

In this case the message starting char and the message closing char will be entered just one time, in the string beginning and at the end.

All the commands in string will not execute until the closing char will be entered.

Separate response will be sent for every command in the chain.

Input string max length:

64 characters.

Backward support:

Design note: Transparent support for Protocol 2000 will be implemented by switch Protocol command from Protocol 3000 to Protocol 2000, in Protocol 2000 there is already such a command to switch Protocol to ASCII Protocol (#56 : H38 H80 H83 H81).

16.3 Kramer Protocol 2000

This RS-232/RS-485 communication protocol uses four bytes of information as defined below. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.

4th byte
1^st BYTE: Bit 7 - Defined as 0.
D - "DESTINATION": 0 - for sending information to the switchers (from the PC);
1 - for sending to the PC (from the switcher).
N5...N0 - "INSTRUCTION"
The function that is to be performed by the switcher(s) is defined by the INSTRUCTION (6 bits). Similarly, if a function is performed via the machine's keyboard, then these bits are set with the INSTRUCTION NO., which was performed. The instruction codes are defined according to the table below (INSTRUCTION NO. is the value to be set for N5...N0).
2nd BYTE: Bit 7 - Defined as 1. I6...I0 - "INPUT"
When switching (ie. instruction codes 1 and 2), the INPUT (7 bits) is set as the input number which is to be switched. Similarly, if switching is done via the machine's front-panel, then these bits are set with the INPUT NUMBER which was switched. For other operations, these bits are defined according to the table.
3^rd BYTE: Bit 7 - Defined as 1.
O6...O0 - "OUTPUT".
When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if switching is done via the machine's front-panel, then these bits are set with the OUTPUT NUMBER which was switched. For other operations, these bits are defined according to the table.

4^th BYTE: Bit 7 - Defined as 1.

Bit 5 – Don't care.

OVR - Machine number override.

M4...M0 - MACHINE NUMBER.

Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept (implement) the command, and the addressed machine will reply.

For a single machine controlled via the serial port, always set M4...M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.

NOTES on the above table:
NOTE 1 - When the master switcher is reset, (e.g. when it is turned on), the reset code is sent to the PC. If this code is sent to the switchers, it will reset according to the present power-down settings.
NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the HEX code 01 85 88 83
was sent from the PC, then the switcher (machine 3) will switch input 5 to output 8. If the user switched input 1 to output 7 via the front panel keypad, then the switcher will send HEX codes:
41 81 87 83
to the PC.
When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by sending to the PC the same four bytes that it was sent (except for the first byte, where the DESTINATION bit is set high).
NOTE 3 - SETUP # 0 is the present setting. SETUP # 1 and higher are the settings saved in the switcher's memory, (i.e. those used for Store and Recall).
NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively. For example, if the present status of machine number 5 is breakaway setting, then the reply to the HEX code

0B	80	80	85
would be HEX codes
4B	80	81	85

NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction code).
If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function, even for the case that the function is not defined. For example, for a video switcher which always switches during the VIS of input #1, (and its VIS setting cannot be programmed otherwise), the reply to the HEX code
0A FE 80 81 (ie. request VIS setting, with INPUT set as 126dec)
would be HEX codes
4A FE 81 81 (ie. VIS setting = 1, which is defined as VIS from input #1).

NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not defined / no valid input is detected; or 1 if it is defined / valid input is detected.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.

NOTE 10 - This code is reserved for internal use.

NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to the request to send the audio machine name would be (HEX codes):

7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).

If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine will send its software version number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to send the version number would be (HEX codes):

7D 83 85 81 (i.e. 128dec+3dec for 2nd byte, 128dec+5dec for 3rd byte).

If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine's name is sent. For example, for the VS-7588YC, the reply to the request to send the first suffix would be (HEX codes):

7D D9 C3 81 (i.e. 128dec+ ASCII for "Y"; 128dec+ ASCII for "C").

NOTE 14 - The number of inputs and outputs refers to the specific machine which is being addressed, not to the system. For example, if six 16X16 matrices are configured to make a 48X32 system (48 inputs, 32 outputs), the reply to the HEX code

3E 82 81 82 (ie. request the number of outputs)

would be HEX codes

7E 82 90 82

ie. 16 outputs

NOTE 16 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.

NOTE 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte. The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes.

NOTE 24 – Further information needed in instructions 21, 22, 25 and 26, is sent using instruction 42 – which is sent prior to the instruction. For example, to request the audio gain value of right input #9, send hex codes

2A 84 80 81

and then send HEX codes

19 89 81 81.

To set MIX mode, send hex codes

2A 81 84 81

and then send HEX codes

16

NOTE 25 – For units which detect the validity of the video inputs, Instruction 16 will be sent whenever the unit detects a change in the state of an input (in real-time).

For example, if input 3 is detected as invalid, the unit will send the HEX codes

10 83 84 81

If input 7 is detected as valid, then the unit will send HEX codes

10 87 85 81.
