Audio Input; Gpio - General Purpose Input/Output Ports; Ir Connector - Lightware HDMI-TPS-TX210 User Manual

2.5.8. Audio input

The connector is used for asymmetric analog audio input signal. It is also known as (3.5
mm or approx. 1/8") audio jack, phone jack, phone plug and mini-jack plug.
2.5.9. GPIO – General purpose input/output ports
Advanced models have seven GPIO pins, which operate 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). The signal levels are the followings:
Info: The total available current of the controller is 180 mA.
Compatible plug type
Phoenix® Combicon series (3.5mm pitch 8-pole), type: MC 1.5/8-ST-3.5, order #: 1840421.

2.5.10. IR connector

IR receiver and IR transmitter can be connected to the transmitter with TRS (Tip, Ring, and
Sleeve) connectors. They are also known as (3,5 mm or approx. 1/8") audio jack, phone
