SYSTEM MODULE DESCRIPTIONS
Power Supply Module - AD1603N
The AD1603N Power Supply Module (PSM) converts the
input AC power to the necessary DC voltages which are
supplied to all the modules in the AD1650B bay. In multiple
bay systems, the AD1603N PSM also provides power to bays
that do not have a Power Supply Module.
Power Panels
In bays which have an AD1603N PSM, the rear Power Panel,
shown below, provides four 8-pin modular RS-232 ports,
labeled 1 through 4, for connection of RS-232 devices such as
Keyboards, Alarm Interface Units, Port Expanders, computers,
etc. The rear panel also provides a 12-pin interface connector,
labeled J1 OUT, for connection of Control Code to code-
controlled accessories, such as Code Distributors, Receivers,
etc. The J1 OUT connector also distributes power to bays
which do not have an AD1603N PSM.
In multiple bay systems, certain bays do not have an AD1603N
PSM. For these bays, a rear Power Panel is provided for
receipt of power and data signals from the AD1603N PSM in
the bays with the PSM. This Power Panel, shown below,
provides a 12-pin connector, labeled J1 OUT, for connection
of Control Code and power signals from the PSM.
Central Processing Module - AD1661B
The AD1661B Central Processing Module (CPM) controls the
switching bays for the AD1650B system and provides the on-
screen programming menus for setup of the system (see
System Programming Manual, OP1650BSPB). The AD1661
CPM rear panel provides eight 2-wire keyboard input ports and
a programming monitor video output BNC connector, labeled
PROG MON, as shown below.
CPM with Data Interconnect Panel - AD1663B
For multiple bay systems, the AD1663B Central Processing
Module (CPM) controls the switching bays for the AD1650B
system and provides the programming menus for setup of the
system. A Data Interconnect Panel is provided with the
AD1663B CPM to distribute data and control signals to other
bays in the system. Three 8-pin modular RS-232 output ports,
labeled J2, J3, and J4, are provided on the Data Interconnect
Panel for output of these signals.
The AD1663B CPM is the same as the AD1661B CPM, above,
with the addition of this panel. This module provides all
keyboard input ports, the PROG MON BNC, and the RS-232
ports, as illustrated below.
