Instruction Manual – DXLink™ Twisted Pair Transmitters/Receiver
Receiver Module LEDs
* When the output cable is disconnected from the HDMI RX or if no EDID can be found on the destination device,
the last used Scaling Mode LED will be ON. In either case, the HDMI RX will continue to hold its output resolution
to the last known preferred resolution until a power cycle or reconnection of a sink with a valid EDID. On power
up without a valid EDID, the default preferred output resolution presented will be 1280x1024 @ 60 Hz until a
different EDID is detected.
Note: For detailed behavior of the NetLinx Link/Act and Status LEDs on the module’s front, see
page 61. For detailed behavior of the RJ-45 connectors’ LEDs on the module’s rear, see page 48
through page 48.

The following components are located on the rear of the HDMI RX (left to right):
Power Jack
Important: If desktop power is used to power the Receiver, only the provided desktop power supply
should be used and it must not
be altered in any way. Remote power can also be provided via a
switcher, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).
The power receptacle is a 2.1 mm DC jack for connecting power. Power can come from a locally
connected DC supply of 12 V. An automatically adjusting universal 110/220 IEC power supply is
provided. The power supply is ENERGY STAR
®
qualified to ensure maximum efficiency and savings.
