Hardware Reference Manual – DXLink™ Twisted Pair 4K Transmitters/Receivers
Optional: IR Control on DXLink Modules
IMPORTANT:
The information in this section does not pertain to the 4K HDMI Wallplate TX as the device does not use serial or IR
communication (for information on DXLink Transmitters that are compatible with the DXLink Twisted Pair 4K HDMI Receiver, see the
“DXLink Compatibility Appendix” on page 89).
For additional information on the IR03 and CC-NIRC, which are required for IR control, see the units’ product pages at
www.amx.com (IR03 and CC-NIRC are not included with Modules). A compatible remote control unit can also be used with the
system. In addition to being directly connected to a device, IR ports can be connected as independent native NetLinx control ports
from networked NetLinx Central Controllers.
IMPORTANT:
When a Transmitter and Receiver are used as a standalone pair, IR control is passed through directly in Extender Mode
when #2 Toggle is set to OFF (default). When #2 Toggle is set to ON, the Master handles the IR control. When a Transmitter and
Receiver are connected to a switcher, they default to Endpoint mode and the integrated Master handles the SEND_COMMANDs.
The IR Receiver is connected to the IR RX port on the Transmitter Module, and the IR Emitter is connected to the IR TX port on the
Receiver Module, or the connections can be reversed.
IR03 External IR Receiver Module (not included)
To connect an IR Receiver to a DXLink Module:
1.
Connect the jack on the IR03 External IR Receiver Module cable (FG-IR03) to the IR RX port on the Module.
2.
Run the cable and attach the IR receiver bud so that it has a clear line-of-sight with the intended remote control device.
CC-NIRC NetLinx IR Emitter Cable (not included)
To connect an IR Emitter to a DXLink Module:
1.
Connect the Phoenix connector on the CC-NIRC NetLinx IR Emitter cable (FG10-000-11) to the IR TX port on the Module.
2.
Run the other end of the IR Emitter cable to the display device and locate the IR window.
3.
Attach the IR Emitter bud over the device’s IR sensor by removing the cover on the reverse side of the Emitter and sticking the
bud directly over the IR window.
IMPORTANT:
For systems that include a switcher – when installation of the IR Receiver and IR Emitter is complete, load the
appropriate driver (for instructions, see page 43) and program the IR remote according to the product’s documentation.
IR Control – Endpoint Mode and SEND_COMMANDs
In Endpoint Mode (Modules connected to a switcher), IR operations are handled by the host providing control of the endpoints. The
Master’s programming specifies where the IR commands are sent (this is handled independently from the routing of the video
signals). For additional information on Endpoint Mode, see page 21. For IR SEND_COMMANDs, see page 53.
