NOTE: You need two key- board data cables for this connection. You must modify one cable as ex- plained in Keyboard Wiring on the next page.

CONNECTING THE MDA TO A CM9760-KBD KEYBOARD

(Refer to Figure 6). Perform this step if you are going to program your CM9760-MDA unit using the CM9760-KBD keyboard. Connect the serial port of your keyboard to the COM 1 port on the MDA unit. To do more than one MDA unit, each time you will need to unhook the keyboard from the MDA unit you just programmed and hook the keyboard to the next MDA unit.

CONNECTING THE MDA TO A KBD200A OR KBD300A KEYBOARD

A single KBD200A or KBD300A keyboard can be used to program the CM9760-MDA Master Distribution Amplifier. The keyboard is connected to the COM 1 port of the distribu- tion amplifier through a KBDKIT (120 VAC) or KBDKIT-X (230 VAC) wall block and a specially modified keyboard data cable. Connect your monitor as shown in Figure 6.

Switch Settings

To set the switches in the keyboard (refer to Figure 7):

1.Remove the two screws and the DIP switch cover plate from the rear of the keyboard.

2.Place switches 5 and 8 in the ON position. This selects the CM9760-MDA mode of operation.

3.Replace the cover plate.
