Installing in a Rack

This section provides instructions for rack mounting VM-218DTxr. Before installing in a rack,
verify that the environment is within the recommended range:

• Operation temperature – 0 to 40C (32 to 104F).

• Storage temperature – -40 to +70C (-40 to +158F).

• Humidity – 10% to 90%, RHL non-condensing.

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

• It is located within recommended environmental conditions. Operating ambient
temperature of a closed or multi-unit rack assembly may exceed ambient room
temperature.

• Once rack mounted, there is enough air flow around VM-218DTxr.

• VM-218DTxr is placed upright in the correct horizontal position.

• You do not overload the circuit(s). When connecting VM-218DTxr to the supply

circuit, overloading the circuits may 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.

• VM-218DTxr is earthed (grounded) and connected only to an electricity socket with
grounding. Pay particular attention when electricity is supplied indirectly (for
example, when the power cord is not plugged directly into the wall socket but to an
extension cable or power strip). Use only the supplied power cord.

To rack mount the machine, attach both ear brackets (by removing the
screws from each side of the machine and replacing those screws
through the `ear brackets) or place the machine on a table.

• Detachable rack ears can be removed for desktop use.

• Always mount VM-218DTxr in the rack before connecting any cables or power.

Extending Control Signals

VM-218DTxr can extend IR, RS-232 and Ethernet control signals to peripheral devices that

are connected to the relevant ports on the transmitter and receivers that are connected to the

VM-218DTxr.
VM-218DT can extend IR and RS-232 control signals in the same way.

The following procedures provide examples for extending signals.

You can extend only one type of signal (RS-232, IR or Ethernet-for VM-218DTxr only) to
control a peripheral device.
Figure 3 (for VM-218DTxr) and Figure 4 (for VM-218DT) show several types of signal
extensions for each HDBT device, for illustrating device capabilities only.

IR Extension

Use the IR 3.5mm mini jacks for the HDBT input and outputs to extend IR control
signals between any set of IR ports on the HDBT transmitter and receivers.

To extend an IR signal, for example, from VM-218DTxr to Projector B:

1. Connect an IR sensor cable to the OUT 5 IR 3.5mm mini jack.

2. Connect an IR emitter cable between the TP-780Rxr receiver (that is connected to
OUT 5) and Projector B.

3. Point the Projector B IR remote-control transmitter to the IR sensor to control Projector B
via the TP-580Rxr receiver that is connected to HDBT OUT 5.

In the same way you can control other peripheral devices connected to the HDBT-connected
transmitter and/or receivers.

To extend an IR signal, for example, from a remote room controller to Projector A:

1. Connect an IR cable between a room controller (for example, Kramer SL-240C) and the
IR port of the IN 2 HDBT-connected on the TP-780Txr transmitter.

2. Connect an IR cable between the IN 2 IR 3.5mm mini jack and the OUT 3 3.5mm mini
jack.

3. Connect an IR emitter cable between the IR port of the TP-780Rxr receiver that is
connected to OUT 3 and the IR port on Projector A.

4. Send an IR signal from the room controller to Projector A via the IN 2 TP-780Txr
transmitter and the OUT 3 TP-780Rxr receiver.

Kramer Electronics Ltd.

11

In the same way you can pass IR signals to control other connected peripheral devices using
the IR ports of the VM-218DTxr, HDBT transmitter and HDBT receivers.

RS-232 Extension

Use the RS-232 3-pin terminal block connectors for the HDBT input and outputs to
extend RS-232 control signals between any set of RS-232 ports on the HDBT transmitter and
receivers.

To extend an RS-232 signal, for example, from VM-218DTxr to Projector B:

1. Connect OUT 5 RS-232 3-pin terminal block connector to a room controller (for example,
the Kramer SL-240C room controller.

2. Connect the RS-232 port on the TP-780Rxr receiver (that is connected to HDBT OUT 5)
to Projector B.

3. Send an RS-232 command from the room controller to Projector B.

In the same way you can control other peripheral devices that are connected to the
transmitter and/or receivers.

To extend an RS-232 signal, for example, from a remote room controller to Projector A:

1. Connect an RS-232 cable between a room controller (for example, Kramer SL-240C)
and the RS-232 port on the TP-780Txr transmitter that is connected to HDBT IN 2.

2. Connect an RS-232 cable between the IN 2 RS-232 3-pin terminal block connector and
the OUT 3 RS-232 3-pin terminal block connector.

3. Connect an RS-232 cable between the TP-780Rxr (that is connected to OUT 3 HDBT)
RS-232 port and Projector A.

4. Send an RS-232 command from the room controller to Projector A on the TP-780Rxr via
the HDBT IN 1 port.

In the same way you can send RS-232 commands to control other peripheral devices
connected to the transmitter/receivers.

In the same way you can send RS-232 signals and commands to control other peripheral
devices connected between the RS-232 ports of the VM-218DTxr, HDBT transmitter and
HDBT receivers.

Ethernet Extension (VM-218DTxr only)

Use the ETHERNET RJ-45 port input and outputs to extend Ethernet signals via
control devices and/or control software to and from the HDBT transmitter/receivers.

To send a command from a room controller, for example, to the display:

1. Connect the ETHERNET RJ-45 port to the Ethernet.

2. Connect the ETH port of a room controller (for example, the Kramer SL-240C room
controller) to the Ethernet.

3. Send an RS-232 command from the room controller to the display on the TP-780Rxr via
the HDBT OUT 7 port.

In the same way you can control other peripheral devices connected to the
transmitter/receivers.

Controlling VM-218DTxr via RS-232 CONTROL

VM-218DTxr features an RS-232 CONTROL 3-pin terminal block connector allowing the

RS-232 to control the VM-218DTxr. To do so, connect the VM-218DTxr to a controller (for
example a PC) via the RS-232 CONTROL terminal block on the rear panel as follows:

• Pin 2 to the TX pin on the VM-218DTxr
RS-232 CONTROL terminal block.

• Pin 3 to the RX pin on the VM-218DTxr
RS-232 CONTROL terminal block.

• Pin 5 to the G pin on the VM-218DTxr
RS-232 CONTROL terminal block.

VM-218DTxr, VM-218DT – Operating and Controlling the VM-218DTxr

15

Operating and Controlling the VM-218DTxr

Control VM-218DTxr in the following ways:

• Using the Front Panel Buttons on page 15.

• Acquiring the EDID on page 15.

• Using the Ethernet on page 16.

Using the Front Panel Buttons

Use the VM-218DTxr front panel buttons:

• Press VOLUME and to set the analog audio output volume.

• Press INPUT to select the required input (indicated by HDMI and HDBT LEDs ).

• Press EDID SELECT and EDID READ to acquire the EDID (see Acquiring the

EDID on page 15).

Acquiring the EDID

Initially, each input on the VM-218DTxr has a factory default EDID loaded (see Default EDID
on page 38). This lets you connect the power to VM-218DTxr while an active source is
connected before having to connect one of the acceptors. VM-218DTxr reads the EDID,
which is stored in the non-volatile memory and uses it for the active connected sources.

In the same way, the acquired EDID from a connected output or an external source is stored
in the non-volatile memory.

You can acquire the EDID from any of the following sources:

• DEFAULT: The factory default EDID.

• OUTPUT: Active acceptors that are connected to OUT 1 HDMI or OUT (2 to 9) HDBT.

• EXTERNAL: A custom EDID (acquired via EDID Designer software, by connecting a PC

to VM-218DTxrt via RS-232 or USB ports).

You can acquire the EDID using:

• The front panel buttons (see Acquiring EDID via the Front Panel Buttons on page 16)

• The embedded web pages (see Managing EDID on page 24)

• EDID Designer software.

VM-218DTxr Supports EDID Designer (via the mini USB port) that can be

loaded from our Web site: Kramer EDID Designer.
To use the mini USB port, you need to download and the Kramer USB driver

from our Web site at: www.kramerav.com/support/product_downloads.asp and
install it.

Acquiring EDID via the Front Panel Buttons

The following procedure is usually done only once, when the device is being set up.

To acquire the EDID:

1. Press EDID SELECT repeatedly until the required EDID source is selected, (either
DEFAULT, EXT, or OUTPUT LED lights ).

When selecting OUTPUT, keep pressing repeatedly to select the desired output.
The relevant LED lights green.

2. Press EDID READ .

EDID READ flashes once and the EDID is copied to the currently selected input.

EDID READ flashing 3 times indicates that the EDID was not read.

The device reverts to the last stored EDID type, as indicated by the relevant EDID
TYPE LEDs.

If the EDID READ button is not pressed for five seconds, the procedure is terminated, the
device does not store a new EDID and the OUTPUT 1 to 9 LEDs revert to normal operation.

Forcing the RGB Mode

Normally (the default state), when acquiring EDID, the device supports any color space that is
defined in the acquired EDID parameters. In case of a color space problem, enabling Force
RGB mode may improve the colors of the image on the display.

Force RGB mode is enabled via the DIP-switches on the rear panel (see Setting the DIP-

switches on page 13).

Using the Ethernet

You can connect to the VM-218DTxr via Ethernet using either of the following methods:

• Locally, directly to the laptop using a crossover cable (see Connecting the Ethernet Port

Directly to a Laptop on page 17).

• Remotely over IP LAN, via a network hub, switch, or router, using a straight-through
cable (see Connecting the Ethernet Port via IP LAN on page 19).

Note: If you want to connect via a router and your IT system is based on IPv6, speak to your
IT department for specific installation instructions.
