3.1 About HDMI—General Description

High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital audio/video interface, widely supported in the entertainment and home cinema industry. HDMI ensures an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digital-to-analog conversions. It delivers the maximum high-definition image and sound quality in use today. Note that Kramer Electronics Limited is an HDMI Adopter and an HDCP Licensee.

HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI licensing LLC.

In particular, HDMI:

• Provides a simple interface between any audio/video source, such as a set-top box, DVD player, or A/V receiver and video monitor, such as a digital flat LCD / plasma television (DTV), over a single lengthy cable
  SIMPLICITY - With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables currently used in A/V systems is reduced LENGTHY CABLE - HDMI technology has been designed to use standard copper cable construction at up to 15m
  • Supports standard, enhanced, high-definition video, and multi-channel digital audio on a single cable
  MULTI-CHANNEL DIGITAL AUDIO - HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to support Dolby 5.1 audio and high-resolution audio formats
• Transmits all ATSC HDTV standards and supports 8-channel digital audio, with bandwidth to spare to accommodate future enhancements and requirements
• Benefits consumers by providing superior, uncompressed digital video quality via a single cable, and user-friendly connector HDMI provides the quality and functionality of a digital interface while also supporting uncompressed video formats in a simple, cost-effective manner
  • Is backward-compatible with DVI (Digital Visual Interface)
• Supports CEC, two-way communication between the video source (such as a DVD player) and the digital television, enabling new functionality such as automatic configuration and one-button play
• Has the capacity to support existing high-definition video formats (720p, 1080i, and 1080p @60Hz), standard definition formats such as NTSC or PAL, as well as 480p and 576p

3.2 About HDCP—General Description

The High-Bandwidth Digital Content Protection (HDCP) standard developed by Intel protects digital video and audio signals transmitted over DVI or HDMI connections between two HDCP-enabled devices to eliminate the reproduction of copyrighted material. To protect copyright holders (such as movie studios) from having their programs copied and shared, the HDCP standard provides for the secure and encrypted transmission of digital signals.

4 Installing in a Rack

This section provides instructions for rack mounting the unit.

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 rods (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:

• In some models, the front panel may feature built-in rack ears
- Detachable rack ears can be removed for desktop use
• Always mount the machine in the rack before you attach any cables or connect the machine to the power
- If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions available from our Web site

5 Connecting the VS-161H 16x1 HDMI Switcher

Figure 2: Connecting the VS-161H 16x1 HDMI Switcher

To connect the VS-161H 16x1 HDMI Switcher as illustrated in the example in

Figure 2:

1. If required:

• Set the appropriate INPUTS to the DVD/PC mode
  Acquire the EDID

2. Connect the HDMI sources as follows:

■ A multimedia player to INPUT 1
A set top box to INPUT 2
■ A DVD player to INPUT 6
■ A DVD player to INPUT 16

1. Connect the OUTPUT HDMI connector to an HDMI acceptor (for example, a plasma display).
2. If required, connect a PC and/or controller to the RS-232 port and/or the Ethernet port.
3. Connect the power cord and power the device on.

Note: The Mute button flashes if the EDID of the device connected to the output is different from the EDID which is currently stored.

5.1 Connecting to the VS-161H Using the RS-232 Connection

You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5.

Method A (Figure 3)—Connect the RS-232 9-pin D-sub port on the unit via a crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be connected) to the RS-232 9-pin D-sub port on the PC.

Note: There is no need to connect any other pins.

Figure 3: Crossed Cable RS-232 Connection

Hardware flow control is not required for this unit. In the rare case where a controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on the controller side.

Method B (Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the null-modem adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all nine wires for a full connection of the D-sub connector. Because the null-modem adapter (which already includes the flow control jumpering described in Method A above) only requires pins 2, 3 and 5 to be connected, you are free to decide whether to connect only these 3 pins or all 9 pins.

Figure 4: Straight Cable RS-232 Connection with a Null Modem Adapter

6 Operating the VS-161H 16x1 HDMI Switcher

This section describes:

• The PC and DVD modes (see Section 6.1)
• Acquiring the EDID (see Section 6.2)
- Locking and unlocking the front panel buttons (see Section 6.3)
- Resetting to the factory default values (see Section 6.4)
• Upgrading the firmware (see Section 6.5)

6.1 The PC and DVD Modes

The VS-161H has two operation modes that are specific per input: the PC mode and the DVD mode:

• The PC mode is used when connecting a computer or several computers to one or more of the inputs via a DVI-to-HDMI converter cable (for example, the Kramer HDMI-DVI Gold Plated Cable in various lengths). This is the default mode
• The DVD mode is used when connecting a DVD or several DVDs to the inputs

When in the PC mode, the input has access to the EDID (default or acquired) to prevent the computer from resetting if an output is not connected. In the DVD mode, the EDID of the connected output is available only when the input to which the DVD is connected, is switched to the output.

The PC mode and the DVD mode can be applied to a single input or to several inputs. For example, if you want to connect a computer to INPUT 1, another computer to INPUT 2, and DVD machines to all the other inputs (from INPUT 3 to INPUT 16), set INPUT 1 and INPUT 2 to the PC mode and all the other inputs to the DVD mode.

To set the inputs to either the PC or the DVD mode:

1. Turn the power off.

2. Press the PANEL LOCK button while turning the POWER on again. The INPUT buttons flash simultaneously.

3. Keep pressing and holding the PANEL LOCK button for a few seconds and then release it.

The PANEL LOCK button flashes. If an input button lights this indicates that that input is set to the DVD mode. If no input button lights this indicates that that input is set to the PC mode.

1. Toggle between the PC mode (input button not lit) and the DVD mode (input button lights) by pressing that input.

2. Press the PANEL LOCK button to exit this mode.

3. You can connect a computer to the input(s) that is set to the PC mode and a DVD to the input(s) that is set to the DVD mode.

The following table summarizes the differences between the PC mode and the DVD mode.

PC Mode	DVD Mode
The input is connected to a computer	The input is connected to a multimedia application, such as a DVD, a set top box and so on
The EDID is available at all times (to prevent computer reset)	The EDID is available only when that input is connected to an output
The input EDID source is the default EDID or an acquired EDID (see Section 6.2)	The input EDID source is acquired directly from the connected output

6.2 Acquiring the EDID

The acquired EDID is used when an input is set to the PC mode.

To acquire the EDID:

1. Turn the POWER off.

2. Press the PANEL LOCK button and the INPUT 16 button while turning the POWER on again.
   The INPUT buttons flash in sequence until the unit has completed reading the EDID.

3. Release the PANEL LOCK and INPUT 16 buttons. If an output was connected, the output EDID is read to all the inputs. If an output was not connected to the machine, the default EDID is read to the inputs.

Note: The Mute button flashes if the EDID of the device connected to the output is different from the EDID which is currently stored.

6.3 Locking and Unlocking the Front Panel

To lock and unlock the front panel buttons:

1. Press and hold the Panel Lock button until the button lights. The front panel buttons are locked.
2. Press and hold the Panel Lock button again until the button no longer lights. The front panel buttons are unlocked.

9 Kramer Protocol 2000

The Kramer Protocol 2-000 RS-232/RS-485 communication uses four bytes of information as defined below. All the values in the table are decimal, unless otherwise stated.

MSB
LSB

	DESTINATION	INSTRUCTION
0	D	N5	N4	N3	N2	N1	N0
7	6	5	4	3	2	1	0

1st byte

	INPUT
1	I6	I5	I4	I3	I2	I1	I0
7	6	5	4	3	2	1	0

2nd byte

	OUTPUT
1	O6	O5	O4	O3	O2	O1	O0
7	6	5	4	3	2	1	0

3rd byte

1	OVR	X	M4	M3	M2	M1	M0
7	6	5	4	3	2	1	0

4th byte

1st 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.

16...10 - "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.

3rd 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.

4th 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 accept (implement) the command, and the addressed machine replies. 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.

Instruction Codes for Protocol 2000
Instruction		Definition for Specific Instruction		Notes
#	Description	Input	Output
1	SWITCH VIDEO	Set equal to video input which is to be switched(0 = disconnect)	Set equal to video output which is to be switched(0 = to all the outputs)	2, 15
30	LOCK FRONT PANEL	0 - Panel unlocked1 - Panel locked	0	2

NOTES on the above table:

NOTE 2 - These are bi-directional definitions. That is, if the switcher receives the code, it performs 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) switches input 5 to output 8. If the user switched input 1 to output 7 via the front panel keypad, then the switcher sends 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 15 – When the OVR bit (4th byte) is set, then the "video" commands have universal meaning. For example, instruction 1 (SWITCH VIDEO) causes all units (including audio, data, etc.) to switch. Similarly, if a machine is in "FOLLOW" mode, it performs any "video" instruction.
