About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the HDBaseT Alliance). It is particularly suitable in the ProAV – and also the home – environment as a digital networking alternative, where it enables you to replace numerous cables and connectors by a single LAN cable used to transmit, for example, uncompressed full high-definition video, audio, IR, as well as various control signals.
Using Twisted Pair Cable for HDBT
Kramer engineers have developed special twisted pair cables to best match our digital twisted pair products that significantly outperform regular CAT 5 / CAT 6 cables.
We strongly recommend that you use shielded twisted pair cable. For details, go to our website at www.kramerav.com/product/VM-2DT.

Operating the VM-2DT
This section describes how to:
- Route the IR and RS-232 signals via the HDBT ports (see Routing the IR and RS-232 Signals on page 6).
• Acquire the EDID (see Acquiring an EDID on page 9).
- Perform Firmware upgrade via K-Upload (see Upgrading the Firmware on page 10).
Routing the IR and RS-232 Signals
VM-2DT transports IR and RS-232 signals between the HDBT input and the two HDBT outputs. Each signal can pass bidirectional commands via the VM-2DT HDBT ports (one input and two outputs).
The IR/RS-232 signal routing is set via the SETUP DIP-switches ⑨.
Setting the DIP-Switches for Routing
Set the DIP-switches as defined by the following table:
| 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 |
DIP-switches 3, 4, 7 and 8 are preserved for future use.
By default, all DIP-switches are set to OFF (up).
Figure 3: VM-2DT DIP-Switches
For example, in the DIP-switch setup shown in Figure 4, DIPs 1, and 6 are set to OFF (up). This means that IR signals can traverse between IN and OUT 1 ports and RS-232 commands can traverse between IN and OUT 2 ports. DIP-switches 2 and 5 are set to ON (down) and are therefore disabled.
Figure 4: VM-2DT DIP-Switches Setup
Signal Routing Example
The example in Figure 5 shows the VM-2DT connected to two TP-580R devices. The table below summarizes the types of connections:
| Output # | HDMI OUT: | INPUT | IR | RS-232 |
| VM-2DT | TP-580T (Blu-ray player) | Emitter | RC-43SL | |
| TP-580R (1) | Projector | Projector | ||
| TP-580R (2) | Display | Sensor | Display |
RS-232 and IR signals are transparently routed between the VM-2DT source and two acceptors. Since RS-232 is designed for point-to-point communication, make sure that only one RS-232 signal is sent to a destination. However, although only one device may send RS-232 signals down a line, sending RS-232 signals to multiple devices is permissible.
You can send RS-232 signals to an AV device via the transmitter or receivers that are connected to the VM-2DT. If you have set the DIP-switches to traverse to both outputs, any command sent to a destination on one of the outputs will also pass to the other output destination, so you need to be sure that it will not have any unwanted effect on the other destination.
In general, we recommend that you set the DIP-switches to traverse to both outputs only when both destination devices are identical (same vendor and same product model) and avoid sending of concurrent responses.
Routing the IR signal
In the example in Figure 5, an IR emitter cable is connected from TP-580T to the Blu-ray player and an IR sensor cable is connected to the TP-580R (2) receiver for receiving IR remote signals. This setup lets you remotely control the Blu-ray player via the TP-580R (2) receiver device, using the Blu-ray player IR remote control transmitter.
To route the IR signal you have to use the Kramer external IR Receiver cable on one end and the Kramer IR emitter cable on the other end. Note that IR Emitter Extension Cables are also available, if required. For further details, go to our website at www.kramerav.com/product/VM-2DT.
Routing the RS-232 Signal
An RS-232 controller can be used to control the AV devices via the TP-580T RS-232 port by sending RS-232 commands over HDBaseT lines to the remote connected AV devices.
In the example in Figure 5, the Kramer RC-43SL control keypad is used to control AV devices that are connected to both TP-580R (1) and TP-580R (2). RC-43SL is connected to the TP-580T RS-232 port. The RS-232 ports on TP-580R (1) and TP-580R (2) are connected to a projector and display, respectively. This type of setup enables you to control the projector and display via the RC-43SL.
When RC-43SL sends a command to the projector on TP-580R (1), it bears no effect on the display that is connected to TP-580R (2). If TP-580R (1) and TP-580R (2) were connected each to identical projectors, both would respond to the sent RS-232 command.

The VM-2DT 1:2 HDBT Distributor can be operated using the Kramer Protocol 3000 serial commands. The command framing varies according to how you interface with the VM-2DT.
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-2DT. 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 16
• Kramer Protocol 3000 Syntax on page 17
• Protocol 3000 Commands on page 18
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 (|) 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 ( | ). 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:
- CR = Carriage return (ASCII 13 = 0x0D)
• LF = Line feed (ASCII 10 = 0x0A) - SP = 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 SPParameter_1,Parameter_2,... | CR |
- Command String – Formal syntax with command concatenation and addressing:
| Start | Address | Body | Delimiter |
| # | Device_id@ | Command_1Parameter1_1,Parameter1_2,.../Command_2Parameter2_1,Parameter2_2,.../Command_3Parameter3_1,Parameter3_2,...|... | CR |
• Device Message Format:
| Start | Address (optional) | Body | Delimiter |
| ~ | Device_id@ | Message | CR LF |
- Device Long Response – Echoing command:
| Start | Address (optional) | Body | Delimiter |
| ~ | Device_id@ | Command SP [Param1,Param2 ...] result | CR LF |
