MOUNTING
Install the MDA in a standard 19-inch (48.26 cm) equipment rack using standard mounting
hardware. The MDA occupies 5.25 inches (13.34 cm) of vertical space, or three RU (rack
units).
HARDWARE SETUP
The following parts are supplied:
1 CM9760 Master Distribution Amplifier
1 Power cord
1 Data cable (reversed RJ-45 to RJ-45)
1 CM9760-MDA Resource CD
COMMUNICATION
Communication between MDA units, System 9760 CC1 (controller), System 9740 CC1 (con-
troller), KBD200A or KBD300A keyboard, or a host PC is accomplished using serial RS-232,
RS-422, or RS-485 transceivers that can be configured by DIP switches on the PCB (printed
circuit board). The factory default for both COM 1 and COM 2 ports is RS-422.
VERY IMPORTANT:
If
you are going to use RS-232
communication, you must
open the case to set the DIP
switches—do so BEFORE
mounting the MDA unit in
the rack. See the section on
Communication Ports Setup
and the section on
Connect-
ing the MDA to an External
PC
for information.
