    Model MRC88 SYSTEM OVERVIEW The MRC88 is a Eight-source Eight-zone audio/video distribution and control system. The System is comprised of a Control Amp, Eight LCD Keypads, and Eight 283M IR Emitters. Together the Control Amp and the Keypads make up a Whole-house Audio/Video Entertainment system. The Control Amp acts as the Server and the Keypads act as the Clients.

  • Page 21: Mrc88 Controller/Amplifier Physical Location And Mounting

    MRC88 CONTROLLER/AMPLIFIER PHYSICAL LOCATION AND MOUNTING (BASIC/ADVANCED) When you mount the MRC88 Controller, you should plan its location carefully. Pay close attention to each of the following factors (refer to Figure 6A above): 1. The amplifier is convection cooled. That is, it 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.

  • Page 22: Mrc88 Keypad Physical Location And Mounting

    3. If the cabinet contains other heat generating components or you are using several MRC88's in a large multi- zone system, you will have to pay even closer attention to adequate ventilation.

    Figure 9 – Removing the MRC88 Keypad from the wall 1. Insert the MRC88 keypad removal tool into the slot at the bottom of the keypad, as shown in Figure 9, being sure that the tool is inserted so that the “insert to here” line slides under the Keypad. This will reduce the risk of damage to the Keypad or the wall.

  • Page 26: Zone Audio Inputs

    Plug the supplied 283M IR emitters into the appropriate IR Emitter jacks - Figure 3-(26). Be careful to match the source audio and video connection number on the MRC88 to the IR Emitter jack number. This will ensure that the IR control signal will be routed to the correct source component. Find the IR sensor window on the source component and attach the emitter to the components sensor window after removing the protective paper cover on the flat side of the emitter head.

    There are two methods of testing RS232 Command Strings directly from the RS232 Palette Editor: One is directly out of the DragMRC PC’s Comport and the second method is through the MRC88’s RS232 Com Port – Figure 3-(29). Using both methods you can control the component or device directly for confirmation of command string or send the command to an RS232 Utility programming to verify proper output (this is good for Trouble Shooting purposes or for testing the program without the component or device present).

    The MRC88 Controller features two sensing methods. One is Video Sensing. All eight source video inputs are set to detect a video input signal (NTSC and PAL sync). When video is detected, the MRC88 controller knows when to send or not send power commands to keep components in sync with system activity. The other method is Current Sensing.

It is different from the ZPR68 in that the MRC88 has a buffered UART and is therefore able to receive a complete command/query string at one time.
  • Page 87 This setting can be found with the settings for configuring the COM port. For the MRC88 system to recognize incoming ASCII command strings, the string must begin with an ‘!’ and for data queries the string must begin with a ‘?’. All strings must end with a ‘+’. This way it can determine the beginning and end of the string for processing.
