3.1 Using Shielded Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer BC-DGKat623 (CAT 6 23 AWG), and the Kramer BC-DGKat7a23 (CAT
7a 23 AWG) cables. These specially built cables significantly outperform regular
CAT 5/CAT 6 /CAT 7a cables.
3.2 About the Power Connect™ Feature
The Power Connect™ feature here means that only the transmitter needs to be
connected to a power source when the devices are within 90m (270ft) of each
other. The Power Connect™ feature applies as long as the cable can carry power.
The distance does not exceed 90m on standard CAT 5 cable. For longer distances,
heavier gauge cable should be used1
!
.
Warning: Using a TP cable that is incorrectly wired will
cause permanent damage to the device
1 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances

8. Optional—Press the EDID READ button to acquire or change the EDID
information (see Section 5.2).
5.2 Acquiring the EDID
Each input on the VM-114H2C has a factory default EDID loaded3
Section (see 9). This lets you connect the power before having to connect one of the
acceptors.
You can acquire the EDID4
•One output (the relevant output LED flashes)
from:
•The default EDID (all output LEDs flash)
•Up to four connected outputs using the Auto-mix Mode5
To acquire the EDID:
(all output LEDs
light)
1. Connect the output(s) from which you want to acquire the EDID.
2. Press the EDID SELECT button briefly.
The device enters the EDID programming mode. The last acquired EDID is
indicated by the lit LED (for example, if Output LED 2 is lit, the EDID
acquired was from Output 2).
3. Press the EDID SELECT button repeatedly until the required EDID is
indicated based on the patterns described above.
1 Another example is the TP-573
2 Another example is the TP-574
3 The VM-114H2C reads the EDID, which is stored in the non-volatile memory
4 This is usually done only once, when the machine is being set up in an installation Once acquired, the EDID is saved in non-volatile
memory and further acquisition is not necessary
5 The EDID acquired is a weighted average of all the connected outputs For example, if several displays with different resolutions are
connected to the outputs, the acquired EDID supports all the resolutions, as well as other parameters included in the EDID

using long twisted pair cables on INPUT 2.
To disable deep color and acquire EDID:
1. Disconnect the power.
2. Connect the output or outputs from which you want to acquire the EDID.
3. Connect the power while pressing the EDID READ button.
4. Perform steps 3 through 5 in Section 5.2.
To enable deep color and acquire EDID:
1. Disconnect the power.
2. Connect the output or outputs from which you want to acquire the EDID.
3. Connect the power while pressing the EDID SELECT button.
4. Perform steps 3 through 5 in Section 5.2.
5.3 Connecting to the VM-114H2C via RS-232
You can connect to the VM-114H2C via an RS-232 connection using, for
example, a PC. Note that a null-modem adapter/connection is not required.
To connect to the VM-114H2C via RS-232:
•Connect the RS-232 9-pin D-sub rear panel port on the VM-114H2C unit
via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to
pin 5 need to be connected) to the RS-232 9-pin D-sub port on your PC
5.4 RS-232 and IR Control and Pass-through
The VM-114H2C can be controlled via RS-232 and infrared. Depending on how
the RS-232 and IR connections are configured, the device will either respond to
control signals or transparently pass them through to another receiver or
transmitter. Three examples in Sections 5.4.2.1, 5.4.2.2 and 5.4.2.3 of various
configurations illustrate this functionality.

Operating the VM-114H2C

5.4.1 RS-232 Control and Pass-through Using the VM-114H2C
As shown in Figure 3, you can connect a PC (or other serial controller) directly to
the VM-114H2C to control the VM-114H2C.
The VM-114H2C also transparently passes bidirectional RS-232 signals over the
TP cable from the TP-573 transmitter to the TP-574 receiver. For example, a PC
connected to the RS-232 port on the TP-573 can control an RS-232-controllable
device (for example, a projection screen) connected to the TP-574.
Figure 4: VM-114H2C RS-232 Control and Pass-through
5.4.2 Local IR Control and IR Pass-through Using the VM-114H2C
The VM-114H2C provides an IR sensor and a 3.5mm mini jack for connecting a
remote IR emitter or sensor. When the VM-114H2C is connected to suitable
transmitters and receivers (for example, the TP-573 and TP-574), the
VM-114H2C can act as a pass-through for IR control signals, allowing remote
control of multiple devices using multiple IR remote controllers.
When there is no IR sensor or emitter connected to the IR Remote 3.5mm mini
jack, all signals received by the IR sensor on the front panel are passed to the
transmitter and receiver bi-directionally over the TP cable allowing control of
remote devices.
When an IR sensor or emitter is connected to the IR Remote 3.5mm mini jack, the
connection between the IR sensor on the front panel and the IR on the
transmitter/receiver is broken so that any signal received by the IR sensor on the
front panel remains local to the VM-114H2C and controls only the VM-114H2C.
To control any device you need to use the appropriate IR remote controller, for
example, the Kramer remote controller controls Kramer devices, the LCD remote
