BSR100D functions include the following:
• Receives and transmits DRCMSK (Differential Raise Cosine Minimum
Shift Keying) and DF (Direct Frequency) modulation
• Performs receiving and transmitting frequency programming changes
• RSSI output
• Visual control
• Channel monitor control
• PTT control
• On/Off indicator
• Data speeds of 4800 to 19200 bps (9600bps maximum in half channels)
using a standard RS-232 interface
• Power output of 10 watt
• Half duplex or simplex operations
• Transmit control via Request-to-Send (RTS)
• Online diagnostic monitoring
• Offline local and remote diagnostics

2 Radio Module Description
The BSR100D has a built in radio module that acts as a VHF/UHF transceiver
and operates as a two-way base station in half duplex mode at remote central
stations and repeaters.
The BSR100D™ has four sets of radio connectors in the rear of the unit: J1,
J2, J3, J6 (see Figure 3: Radio Connectors J1, J2, J3 & J6 and Table 2: Radio Connector Description for full explanation).

3 Modem Module Description
The BSR100D has a built-in wireless modem that provides a high-speed data link
suitable for a wide variety of applications with system security for diagnostics
reporting.
3.1 Data Port Interface
The BSR100D modem component is equipped with a J4 15-pin data port
interface. The J4 is used for connection between the radio modem and PC for
set-up and data communications (see Figure 4: Data Port Interface).
Figure 4: Data Port Interface
Set-up and data communications require two separate cables to be used. Each
cable is labeled SET-UP or PCDATA cable and is equipped with a male 15pin cable connection to connect directly to the J4 interface, and a
corresponding female 9-pin COM port connector to connect to the PC.
