3. Product Overview
3.3.9. GPIO - General Purpose Input/Output Ports
The TPS-TX220 series and the SW4-TPS-TX240 transmitters 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:
Logical low level
Logical high level
INFO: The maximum total current for the seven GPIO pins is 180 mA.

3.4. TPS Extender Concept
The HDMI-TPS-TX200 series transmitters are able to receive digital (DP, HDMI, DVI-D) video signals and
analog audio signal as well and transmit HDBaseT (TPS) signal including HDMI/DVI audio/video signals,
Ethernet, RS-232, and Infrared signals. Analog audio signals can be received via the 3.5" TRS (jack).
The device can be controlled via Ethernet, RS-232 or Infrared and is able to control third-party devices via the
RS-232, Ethernet, Infrared interfaces.

The following diagram introduces the route of the different signal types (including the audio/ video and
control signals as well) from the input to the output ports in the device.
The diagram is about the SW4-TPS-TX240 transmitter. The principle of the operation is the same for all
models.
