System Error Codes / Troubleshooting
If error codes appear in the LCD (e.g., E01000A), a common troubleshooting
strategy is resending the command to see if the error was simply a timeout error.
Other things to check: link connections, power cables, and power source. If the
system still displays an error code, refer to the instruction manual on the CD or at
www.amx.com.

Multiple Panels
CP-20A Remote Panels can be linked together in a daisy chain to create multiple
control points for a single system. XNNet link cables can be attached to either Comm
Link. The total distance of the cable runs cannot exceed 1,000 ft. (304.8 m).
On large control networks, termination may be required on the last linked control
panel (or device); for termination information, see the control panel instruction
manual (or device documentation).
Rack Installation
CP-20A Remote Panels are designed to fit in a standard EIA 19 in. (48.26 cm) rack.
Optimum viewing angle is at eye level.
To install the CP-20A Remote in a rack:
1.
Wire the CP-20A to the enclosure and to a power source.
2.
Insert the wired panel through the rear of the rack.
3.
Attach panel with front mounting screws.
4.
Apply power to the panel (see below).
5.
After a brief wait, execute a test switch.
Applying Power
Important: Power requirements: +9 VDC @ 500mA. Always use a UL approved
power source. Check the power source's documentation for information specific to
that power source.
On the (optional) AutoPatch wall transformer, the side of the wire with the white
stripe is positive and the other side is ground.
To apply power to the CP-20A Remote:
1.
Unplug the power connector on the CP-20A Remote.
2.
Loosen the two outer screws and insert the power cable wires (FIG. 3).
3.
Tighten both screws and plug the connector back into the remote panel.
4.
Place CP-20A Remote in rack or other permanent location before
applying power.
