Sync Multipoint Short Range Modem

RAD's miniature SRM-5SC is a short range modem connecting full or half duplex synchronous terminals, controllers and computers in point-to-point or point-to-multipoint applications. The modem operates at data rates from 1.2 kbps to 19.2 kbps (selectable) with a range of 5 km (3.0 miles) at 9.6 kbps.

• Ensures integrity of data transmission over unconditioned 4-wire dedicated lines

• No external power required

The miniature SRM-5SC is a short-range modem or short-haul modem connecting full or half duplex synchronous terminals, controllers and computers in point-to-point or point-to-multipoint applications. The modem operates at data rates from 1.2 kbps to 19.2 kbps (selectable) with a range of 5 km (3.0 miles) at 9.6 kbps.

 

The SRM-5SC is a fully compatible subminiature model of the SRM-6SC, offering the same features in half the size.

 

Three alternative sources for transmit timing are available: internal oscillator, external clock from the terminal or loopback clock derived from the receive signal. The carrier can be strapped for continuous operation or switched operation controlled by the RTS signal.

 

The unit has an RS-232-C/V.24 interface and is available with a choice of a male or female integral 25-pin connector for the DTE interface and a 5-screw (4-wire and ground) terminal block for the line. The SRM-5SC has both a terminal block and RJ-45 or RJ-12 as its line connectors.
