INSTALLATION AND PROGRAMMING
GUIDE
INSTALLATION
If the RCS is not used with an external power supply, the UltraMatrix UMC-
_x4 card must first be modified. Only cards where the remote control switch
will be connected to will have to be modified.
5. Remove the UMC 0x4 or UMC 1x4 card from the UltraMatrix
chassis.
6. Locate the 1K resistor R4. It is directly behind the RJ45 connector.
7. Replace R4 with a 10 Ohm, 1/4W, 5% resistor.
8. Install the UMC 0x4 or UMC 1x4 card in the UltraMatrix chassis and
apply power.
