Hardware Reference Manual – DXLink™ Twisted Pair Transmitters/Receiver
The following components are located on the front of the DX-RX (left to right):
Power LED
–
Indicates when the DX-RX is powered on.
Video and Audio LEDs
–
Indicate the presence of video and embedded audio signals through the DX-RX.
Scaling button and LEDs
–
Use the Scaling button to select one of the 3 scaling options: Bypass, Auto (default), or Manual.
For information on using the Scaling button and options for persisting the Scaling Mode, see page 49.
Program port
–
This port is a USB mini-B connector.
IR LEDs
– TX and RX LEDs indicate active IR communication.
232 (RS-232) LEDs
– TX and RX LEDs indicate active serial communication.
NetLinx LEDs
– Link/Act LED indicates network communication activity. The Status LED indicates unit status.
CEC LED
– CEC is not currently supported.
USB LED
– When illuminated, the LED indicates that the USB port connection has been established (for details, see
page 19).
ID Pushbutton
– Places the DX-RX in ID Mode for setting the NetLinx ID (device only) and provides additional functionality,
such as placing the device in Static IP Mode or DHCP Mode.
Receiver Module LEDs
* When the output cable is disconnected from the DX-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 DX-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 1280x1024,60Hz 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 50. For detailed behavior of the
RJ-45 connectors’ LEDs on the module’s rear, see page 40.
Receiver Rear View
The following components are located on the rear of the DX-RX (left to right):
Power Jack
– 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.
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 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
