HDMI 1 in 2 out SPLITTER with IR extender XHDM312
Installation
1. Connect an HDMI cable from an HDMI source (e.g MEGA DVR, DVD Player etc.) to the HDM312
Input. The maximum cable run from the HDMI source is 15m for a 1080P signal or 10m for 4K. If the
distance of the cable run needs to be longer, you can use an *HDM150 HDMI extender prior to and if
necessary following the HDM312. See test results on previous page.
2. Connect an HDMI lead to the Output 1 and 2 on the HDM312 with maximum run of 15 metres and
connect the 2 monitors.
3. Set EDID dipswitch settings. 1111 = 1080P (set if both outputs are 1080P)
0000 = 4K (set if both outputs are 4K)
0011 = EDID Copy (set if both outputs copy input)
1100 = EDID Combination (output 1 is 4K, output 2 is 1080P)
4. Connect the 5vDC 2A regulated power supply to the 2.1mm power jack socket.
5. Using the IR remote facility - optional
If you want to use the IR remote for example controlling the MEGA DVR, see below:
a) Ensure that the adaptor switch is correctly set to IR or CEC. IR is for controlling a standard IR
remote but a CEC IR remote can control multiple devices with the one control. Only one HDMI channel
can use the IR remote.
b) Connect the IR Adaptor into the HDMI connection on the monitor.
c) Connect the HDMI cable from the DVR HDMI output into the IR Adaptor detailed in b).
d) Connect the IR Receiver mini jack plug into the IR Adaptor and remove the cover from the sticky
pad and fix the IR Receiver to the monitor case so that it can be seen by the DVR IR remote controller.
e) Connect the IR Transmitter mini jack plug to the jack socket on the HDM312 and remove the cover
from the sticky pad and fix the IR Receiver to something facing the DVR IR sensor.
f) Now you can use the DVR IR Remote controller by pointing at the IR Receiver attached to the
monitor and you can control the DVR.
* HDM150 Extender can be purchased to increase cable run to and from the HDM312 splitter.
