Telephone Interface
The OSMAC Base Station telephone interface may be utilized for generating command codes or initiating phone patches
with two-way radios. The Base Station has a built-in radio transceiver which enables it to communicate with other two-
way radios. The base station can receive over-the-air commands to generate command codes, connect to the telephone
system, dial phone numbers and answer incoming telephone calls.
External Transceiver
The OSMAC Base Station may utilize an internal transceiver, an external transmitter, or an external transceiver. A 15-pin
D-sub connector is provided on the back panel of the Base Station to facilitate interface with an external transmitter or
external transceiver to the Base Station.
Serial I/O Ports
The OSMAC Base Station has two RS-232 Serial I/O ports. These ports can be used to connect the base station to a
central controller such as SitePro or TouchNet.
Auxiliary/Alarm Connector
A 15-pin D-sub female connector is provided on the back of the unit and labeled as ALARMS. This connector can read
digital inputs used for triggering alarms. The digital inputs can be programmed to automatically generate satellite com-
mands.
Note: All digital alarm inputs have an internal 10K pull-up resistor connected. Alarms are activated by pulling the input to
ground. Open circuit or a TTL/CMOS high level is in the inactive state. Do not pull these inputs above 5V.
