Hardware Reference Manual – DXLink Twisted Pair™ Transmitters/Receiver
3.
ICS LAN 10/100 connector (optional) – Attach a twisted pair cable from this connector to a LAN. (For NetLinx programming
information, see page 64.)
4.
USB port (optional) – Connect to a hub using a USB-A cable; connect keyboard and mouse to the hub. (This port is for
sending keyboard / mouse commands to a PC.) For USB port information, see page 18. For USB SEND_COMMAND
information, see page 77.
5.
Stereo Audio Out connector (optional) – Plug the audio cable (that goes to the audio destination) into the stereo audio jack.
For audio precedence information, see page 41. For information on audio SEND_COMMANDs (including enabling the analog
audio format), see page 68.
* DVI cable can be used instead (via a DVI-to-HDMI cable adapter); however, the advanced audio support from HDMI will not be
available.
NOTE:
The 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. For information, see page 56.
TIP:
If scaling adjustments are necessary, use SEND_COMMANDs (see page 64). If connected to an Enova DGX output, use DGX
Configuration Software via the switcher for scaling.
DX-RX – Applying Power
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 only be provided via the switcher, PDXL-2 (FG1090-170), or PS-POE-AT-TC (FG423-84).
IMPORTANT:
The “Important Power Considerations for Enova DGX Systems” also apply to the DX-RX (see page 31).
To apply power to the DX-RX:
1.
Plug the cord from the desktop power supply (provided) into the power jack on rear of the DX-RX (2.1 mm DC jack for 12 V
local power).
2.
Plug the desktop power supply into an AC external power source.
The Power LED on the front of the DX-RX illuminates a constant green, which indicates a ready state. Some of the additional
LEDs will also turn a turn a constant green. For normal LED display, see the table below.
IMPORTANT:
If any Receivers are being powered through an Enova DGX, we recommend determining the power budget to maintain
power redundancy for the system (see page 44).
DX-RX – Indicator LEDs
The LED indicators are listed in the table as they appear on the front of the RX from left to right.
* 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.
DX-RX – LED Troubleshooting
If the indicator LEDs for the modules do not respond with a normal display as stated in the table above:
Check all power connections.
Check the “Detailed NetLinx (Link/Act and Status) LED Behavior” section on page 50.
Try the suggestions in the “Troubleshooting” chapter (see page 83).
For information on restoring the module’s default settings on power up, see page 57.
