Connecting the VM-4HDT, VM-3HDT and VM-2HDT

Always switch off the power to each device before connecting it to your VM-4HDT. After connecting your VM-4HDT, connect its power and then switch on the power to each device.

To connect the VM-4HDT as illustrated in the example in Figure 4:

Figure 5 illustrates how to connect the VM-3HDT (the same applies to VM-2HDT that has 2 HDBT outputs).

1. Connect an HDMI input source (for example, a Blu-ray disk player) to the HDMI IN connector ⑦
2. Connect each HDBT output ⑨ to an HDBT receiver (for example, The TP-580R or the TP-588D).

If a Mac computer is connected as a source, it will output an HDCP-secured signal that will not pass-through to any connected non-HDCP acceptors.

1. For VM-3HDT and VM-2HDT only, connect the LOOP HDMI connector ⑧ to an HDMI acceptor (for example, a VM-4HDT or a local display).

2. If required, connect the IR 3.5mm mini jack to an IR sensor or emitter (for example, an emitter, to control, with its IR remote controller, the projector that is connected to an HDBT receiver). See IR and RS-232 Signal Routing on page 9 for further details.

3. If required, connect a controller (for example, the RC-206 control keypad) to the RS-232 3-pin terminal block connector to control a remote display that is connected to an HDBT receiver. See IR and RS-232 Signal Routing on page 9 for further details.

4. Connect the 5V DC power adapter to the power socket unit and then connect the adapter to the mains electricity (not shown in Figure 4). The ON LED lights.

Operating the VM-4HDT, VM-3HDT and VM-2HDT

This section describes the following functions

• IR and RS-232 Signal Routing on page 9.
• Acquiring an EDID on page 12.

IR and RS-232 Signal Routing

The VM-4HDT can send or receive IR and RS-232 commands via the four HDBT output ports.

Each signal can pass commands from the VM-4HDT to a single output, several outputs or all of the outputs or the other way around, from the output/s to the VM-4HDT.

The IR/RS-232 signal routing is enabled via the SETUP DIP-switches (see Setting the DIP-Switches on page 9).

Setting the DIP-Switches

This section defines the SETUP DIP-Switches:

Output #	IR Routing is enabled when:	RS-232 Routing is enabled when:
OUT 1	DIP 1 – OFF	DIP 5 – OFF
OUT 2	DIP 2 – OFF	DIP 6 – OFF
OUT 3	DIP 3 – OFF	DIP 7 – OFF
OUT 4	DIP 4 – OFF	DIP 8 – OFF

Figure 7: VM-4HDT DIP-Switches

For example, in the DIP-switch setup shown in Figure 8, DIPs 1, 4, 7 and 8 are set to OFF. This means that IR signals can be transferred through channels 1 and 4 and RS-232 commands can be passed via channels 3 and 4. All the other channels are set to ON and therefore their related IR and RS-232 communication is disabled.

Figure 8: VM 4HDT DIP-Switches Setup

Signal Routing

The example in Figure 9 shows the VM-4HDT connected to four TP-580R devices. The table below summarizes the types of connections:

Output #	HDMI OUT:	INPUT	IR	RS-232
VM-4HDT		Streamer	IR Emitter to streamer	Laptop
TP-580R (1)	Display		Streamer IR remote controller to IR Sensor
TP-580R (2)	Display		Streamer IR remote controller to IR Sensor
TP-580R (3)	Projector		Streamer IR remote controller to IR Sensor	Projector
TP-580R (4)	Projector		Streamer IR remote controller to IR Sensor	Projector

IR signal Routing

To route the IR signal you have to use the Kramer external IR sensor on one end and the Kramer IR emitter cable on the other end.

In this example, an IR emitter is connected to the streamer and IR sensors are connected to each TP-580R device. This setup lets you remotely control the streamer via any of the receiver devices using the streamer's IR remote control transmitter.

RS-232 Signal Routing

A laptop or a Kramer Control device (for example, the SL-240C controller) can be used to send RS-232 control commands over HDBaseT to the remote connected device.

In this example, a laptop is connected to the RS-232 terminal block connector on the VM-4HDT and the RS-232 ports on TP-580R (3) and TP-580R (4) are connected to the projector. With this type of setup, you can control the projectors via the laptop.

RS-232 commands are sent to both projectors:

- When identical (for example, both are Projector A models), both respond to these commands.

- When different (for example, Projector A and Projector B models), the Projector A commands affect only Projector A and are ignored by Projector B.

In the same way, if RS-232 is also connected to the displays on TP-580R (1) and TP-580R (2) (not shown in Figure 9) they can also receive specific control commands each, which will be ignored by devices of a different model.

Protocol 3000

The VM-4HDT 1:4 HDMI to HDBT DA can be operated using the Kramer Protocol 3000 serial commands. The command framing varies according to how you interface with the VM-4HDT.

Generally, a basic video input switching command that routes a layer 1 video signal to HDMI out 1 from HDMI input 2 (ROUTE 1, 1, 2), is entered as follows:

• Terminal communication software, such as Hercules:

The framing of the command varies according to the terminal communication software.

• K-Touch Builder (Kramer software):

• K-Config (Kramer configuration software):

All the examples provided in this section are based on using the K-Config software.

You can enter commands directly using terminal communication software (e.g., Hercules) by connecting a PC to the serial or Ethernet port on the VM-4HDT. To enter CR press the Enter key (LF is also sent but is ignored by the command parser).

Commands sent from various non-Kramer controllers (e.g., Crestron) may require special coding for some characters (such as, /x##). For more information, refer to your controller's documentation.

For more information about Protocol 3000 commands, see:

• Understanding Protocol 3000 on page 18.
• Kramer Protocol 3000 Syntax on page 19.
• Kramer Protocol 3000 Commands on page 19.

Understanding Protocol 3000

Protocol 3000 commands are structured according to the following:

• Command – A sequence of ASCII letters (A-Z, a-z and -). A command and its parameters must be separated by at least one space.
• Parameters – A sequence of alphanumeric ASCII characters (0-9, A-Z, a-z and some special characters for specific commands). Parameters are separated by commas.
• Message string – Every command entered as part of a message string begins with a message starting character and ends with a message closing character.

A string can contain more than one command. Commands are separated by a pipe (1) character.

- Message starting character:

• - For host command/query

• \~ – For device response

- Device address – K-NET Device ID followed by @ (optional, K-NET only)

- Query sign – ? follows some commands to define a query request

- Message closing character:

• CR – Carriage return for host messages (ASCII 13)
• CR LF – Carriage return for device messages (ASCII 13) and line-feed (ASCII 10)

- Command chain separator character – Multiple commands can be chained in the same string. Each command is delimited by a pipe character (1). When chaining commands, enter the message starting character and the message closing character only at the beginning and end of the string.

Spaces between parameters or command terms are ignored. Commands in the string do not execute until the closing character is entered. A separate response is sent for every command in the chain.

Kramer Protocol 3000 Syntax

The Kramer Protocol 3000 syntax uses the following delimiters:

• OR = Carriage return (ASCII 13 = 0x0D)
• L = Line feed (ASCII 10 = 0x0A)
• S = Space (ASCII 32 = 0x20)

Some commands have short name syntax in addition to long name syntax to enable faster typing. The response is always in long syntax.

The Protocol 3000 syntax is in the following format:

- Host Message Format:

Start	Address (optional)	Body	Delimiter
#	Device_id@	Message	CR

- Simple Command – Command string with only one command without addressing:

Start	Body	Delimiter
#	Command SP Parameter_1,Parameter_2,...	CR

- Command String – Formal syntax with command concatenation and addressing:

Start	Address	Body	Delimiter
#	Device_id@	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	Dellimiter
~	Device_id@	Message	CR LF

• Device Long Response – Echoing command:

Start	Address (optional)	Body	Delimiter
~	Device_id@	Command SP [Param1,Param2 ...] result	CR LF
