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 62.
For detailed behavior of the RJ-45 connectors’ LEDs on the module’s rear, see page 50.
Receiver Rear View
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.
Note:
The HDMI RX can also be powered through the DXLink connector when it is attached to a DXLink
Output Board in an Enova DGX Switcher. We recommend calculating the power budget for the switcher to
maintain the redundancy of its power supplies (see page 41).

The Receiver is in one of the three modes for scaling
• At initial power up, the Receiver defaults to the Auto scaling option*
• Pressing the Scaling button cycles the module through the options:
Bypass, Auto, and Manual
• If Bypass is solid and Auto is flashing, then the RX is trying to read EDID
from the sink
