Ethernet Connector (LAN Port)
The extender provides standard RJ45 connectors for TPS IN and LAN ports. Always use high
quality Ethernet cable for connecting transmitters and receivers.
Wiring of TPS and LAN Cables
Lightware recommends the termination of LAN cables on the basis of TIA/EIA T 568 A or TIA/EIA T 568 B
standards.

IR Connector
IR detector and IR emitter can be connected to the device with TRS (Tip, Ring, and Sleeve) connectors.
They are also known as (3,5 mm or approx. 1/8”) audio jack, phone jack, phone plug, and mini-jack
plug. The pin assignments are the following for the detector and the emitter:
Detector – 3-pole-TRS
Emitter – 2-pole-TS

INFO:
Ring pole of the emitter is optional. If your IR emitter has three pole-TRS plug, then the Ring and the
Sleeve are the same signal (Output - ).

section.
3.2.11. GPIO - General Purpose Input/Output Ports
UMX-HDMI-140 series switchers contain a 8-pole Phoenix connector with seven GPIO pins, which operates at
TTL digital signal levels and can be set to high or low level (Push-Pull). The direction of the pins can be input or
output (adjustable). Voltage ranges for GPIO inputs are the following:
Input voltage [V]
Output voltage [V]
Max. current [mA]
Logical low level
0 - 0.8
0 - 0.5
30
Logical high level
2 - 5
4.5 - 5
18
INFO:
The maximum total current for the seven GPIO pins is 180 mA.
