Attaching Remote XNNet Control Devices
A remote XNNet control device is any device that sends and receives XNNet protocol over the
REMOTE port. AMX AutoPatch XNNet control devices include SBC control pads, Preset SBC control
pads, and remote control panels.
The instructions below are for attaching a device to the REMOTE port, which is located on the CPU
board. For specific product information, see the individual device’s documentation.
Communication Cable Requirements
 A two-conductor, 20 AWG, 7/28 strand cable with a drain wire or shield, such as Alpha 2412C
(customer supplied)
 Maximum length of cable: 1,000 ft. (305 m) total, including linked panels
To establish a REMOTE port connection with an XNNet device:
1.
Attach one end of the XNNet link cable to the corresponding port on the device (see the individual
product documentation).
2. On the enclosure’s CPU, unplug the REMOTE connector.
3. Loosen the screws on the REMOTE connector.
4. Insert the two wires of the XNNet link cable from the device into the REMOTE connector leaving
the center slot empty (FIG. 11).
Note that either wire can be inserted into either of the outer slots.
5. Tighten both screws and plug the connector back into the CPU.
6. If not already on, apply power first to the Optima SD enclosures before applying power to the
XNNet device (see “Applying Power & Startup,” page 29).
7. Execute a switch to ensure the Optima SD system is working properly (see page 31).
