Installation and Setup
36 Modula Instruction Manual
Attaching External XNNet Controllers
An remote XNNet device is any device that sends and receives XNNet protocol over the Remote
(XNNet) port.
AMX AutoPatch XNNet control devices include remote control panels (e.g., the CP-10 and CP-20A).
AMX AutoPatch XNNet accessory devices include Single Bus Controllers (SBCs) and Preset SBCs.
The instructions below are for attaching a device to the Remote (XNNet) port, found at the bottom of 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 Modula’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. 19).
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 Modula enclosure before applying power to the XNNet
device (see “Applying Power and Startup,”
page 38).
7.
Execute a test switch to ensure the Modula is working properly (see “Executing a Test Switch”, on
page 41).
