MRC88 / MRAUDIO8X8 QUICK START GUIDE 5 SYSTEM PLANNING CONTROLLER LOCATION Consider all of the flowing when planning the Controller location: 1. The MRC88 depends on the natural free flow of air up through the slot perforations in the bottom plate, over the internal heat dissipating fins, then out the top cover, for adequate cooling. 2. Provide large holes in the shelf below the MRC88 and allow at least 2 inches of space above the top cover to allow adequate airflow. 3. Never remove

MRC88 / MRAUDIO8X8 QUICK START GUIDE 6 MOUNTING THE KEYPAD Keypad Location • The MRC88 Keypad should be mounted in a convenient location, typically near the entrance to a room where other room controls such as light switches are located. NOTE: Some light dimmers can interfere with the Keypad and IR Sensor. Test compatibility prior to determining mounting location. • Do not mount the Keypads in locations that will be exposed to sunlight or bright artificial light. Bright light sources

MRC88 / MRAUDIO8X8 QUICK START GUIDE 10 PREPARATION – WIRING CAUTION: Power voltage for the keypad is transmitted along the CAT5 cable! Incorrect wiring on this cable can destroy the MRC Keypad! TERMINATING THE CAT5 CABLES All MRC88 CAT5/RJ45 connections utilize the EIA/TIA 568B Standard pin-out as shown in Figure 7. Figure 7 – CAT5/RJ45 Pin-out (EIA/TIA 568B) Cables should be configured in a pass through (pin to pin) configuration. To terminate CAT5 cables: 1. Trim the end of

MRC88 / MRAUDIO8X8 QUICK START GUIDE 11 Test the cable connections using a proper CAT5 cable tester or use a multimeter to check pin to pin continuity and for possible shorts. Using either method, it is advisable to measure pins 3 and 6 to verify proper voltage. A 12VDC measurement should be read when the positive probe is on pin 6 and the negative probe is on pin 3. See Figure 7. AC POWER It is recommended, but not required, that the MRC88 Controller and head-end source components be
