Equipment operation 1
In a DualMode 800 Enclosure, you can communicate with the Alarm Control
Unit (ACU), the Transmit Receive Unit (TRU) and the Multi-Channel Power
Amplifier (MCPA) by the use of an interface terminal or a computer. You can
use the handset on the DualMode Cell Site Monitor (DCSM) to program the
mobile unit and perform call through test.
This chapter describes the interface commands for configuring and
programming these units in the DualMode 800 Enclosure.
Alarm Control Unit
The MAINTENANCE (Local Terminal) port located on the front of the ACU
gives direct access to the ACU MPU board. You can use this interface to
configure and monitor the alarm input points and the control output contacts.
To access the ACU for local maintenance and monitoring, you need a VT100
(or equivalent) terminal with the following settings:
Stop bit control 1 bit
Word length 8 bits
Parity none
BAUD rate 9600
Interface RS-232C
If you cannot set the terminal to the settings listed, change the ACU
configuration by setting the local terminal switch (SW3) on the MPU board to
match your terminal settings. Refer to Table 5-4 for the settings of SW3 in the
DualMode 800 Enclosure Functional Description, 411-2051-100.
When the terminal and ACU are set correctly, connect the terminal to the
MAINTENANCE port with a null modem cable. Power up the terminal, hold
the CONTROL key and press the Z key. A menu of options will appear on the
screen as shown in Figure 1-1.
