X-Digital System XDS-PRO Quick Start Manual page 6

Each DB-9 connector normally carries one radio program stream, either mono or
stereo. If the program is mono, the same audio appears on the left and right pin
pairs.
In a few, rare cases, the left and right halves of a stereo channel may be used
for unrelated mono programs, but this is no longer the norm.
Your receiver should be pre-configured to output the Test Channel on all ports.
Verify you can hear the test program through all receiver ports.
To manually program the XDS receiver to output the Test Channel on a desired audio
port:
o At the main screen with the network logo, press the SET key, then the left or
right arrows to reach Audio Ports. Press SET.
o Press the left or right arrows to select the Audio Port (letter A, B, C or D).
Press SET.
o Press the left or right arrows to select Program. Press SET.
o Use the up and down arrows to find the Test Channel. Press SET.
1.4 RELAY CLOSURES
There are two DB-37 connectors on the rear panel which together contain a total of 32
mappable relay (or contact) closures to drive your station automation. Relay closure are
momentary Form "A", rated 500ma @24v.
Your XDS receiver may be delivered with a parts kit including two mating DB-37
connectors with shells.
