Radio Design Labs RUSC1A
RS485/RS232 Serial Converter

RUSC1A

The RU-SC1A is part of the group of versatile RACK-UP products from Radio Design Labs. The RACK-UP series features the advanced circuitry for which RDL products are known, combined with accessible, user-friendly controls and displays. The ultra-compact design permits high-density installations, with three products mounted in a single rack unit! Single RACK-UPs can be mounted right where they are needed using the adhesive methods popularized by RDL's STICK-ON series of products. Optional brackets permit mounting a RACK-UP module above, below, or in front of any flat surface. Optional rack-mount adapters (RU-RA3, RC-1U) are available for conventional RACK-UP series installation.

The RU-SC1A is the ideal choice in installations where both RS-232 and RS-485 serial communications protocols are used. Both the RS-485 port and the RS-232 port are provided on the front panel of the RU-SC1A. Power connections are made on the rear panel through full-size, clearly identified, barrier block terminals. When used with the optional RU-FP1, the RS-232 and RS-485 jacks are accessible from the rear of the rack.

The RU-SC1A is a bi-directional, half-duplex serial converter, exchanging data between the RS-232 and RS-485 ports.

As supplied from the factory, the RU-SC1A is set to operate at baud rates of 9,600 to 19,200. Rear terminal jumpers may be programmed for operation at speeds below 9600. Front panel LEDs are provided to show the direction of data flow when data is present from either the RS-232 or RS-485 sources.

Two RU-SC1As may be connected (via the RS-485 ports) over a long distance using balanced, twisted-pair line to permit feeding data between two RS-232 ports, This permits serial communications over much greater distances than with conventional RS-232 serial cables.
