FOCUS 200 PLUS Installation and Setup Guide8-2Wiring the AC ModuleThe module draws 250mA from the FOCUS 200 PLUS’ auxiliary power #2 output. Be sure to include thiscurrent draw in the power calculations.To wire the AC Communicator, perform the following steps:Step Action1 Power down the control unit before making any connections to the AC Module.2 Connect the telephone lines to the module. See Figure 8-1.Notes: 1. If you are using AC telephone lines, connect these to terminals 1 & 2 (seeFigure 8-2).2. If you are using DVACS telephone lines or RS232 port, connect these toterminals 4 - 8. Maximum length of RS232 cable is 50 feet (see Figure 8-3).3. If you are using DC telephone lines, connect these to terminals 9 - 12 (seeFigure 8-4).3 Connect the ribbon cable (supplied) from the 9-pin header on the module to J6 on thecontrol unit’s PC board. Be sure the ribbon cable does not run under the AC moduleboard. The J6 header is static sensitive. Make connections to the header with thepower to the control unit off and after grounding yourself.4 Connect the module’s earth ground (terminal 3) to the control unit’s earth ground(terminal 3 or 4), using 16AWG wire.5 If you are using multiple AC Communicator modules, set the JL/JK header.
