Captive Screw IR Signal Insertion
Figure 32 shows an example of a typical captive screw Ethernet insertion, in which an
Extron control system provides IR control of a display via the switcher. Configure this type of
insertion as follows:

Figure 32. Typical Captive Screw Insertion to an Input Endpoint
1. Connect the control system to the Over TP IR captive screw port (output port 1A in this
example).
2. Connect the TP cable from the IN1804 RJ-45 Out connector to the DTP input of the
endpoint.
3. Connect the endpoint to the device to be controlled.
4. Wire an IR emitter to the IR connector of the twisted pair receiver and place the emitter
on the display device.
