Patton’s Model 1052A is a long-range powered, RS-232 digital modem. Operating synchronously or asynchronously at full duplex over a single twisted pair, the Model 1052A uses 2B1Q modulation for superior signal strength even in noisiest environments. RS-232 serial connections can now be extended to distances over 5 miles (8 km) without the use of repeaters! Using ordinary voice-grade wire, the 1052AS RS-232 Serial Extender provides a cost-effective solution for dedicated end-to-end connections with synchronous line rates up to 128 kbps and asynchronous line rates up to 38.4 kbps including RTS, CTS and DCD modem signals.

The miniature size of the Model 1052A allows for a direct connection to your transmission devices serial port. LEDs are conveniently located on the side of the Model 1052A to provide at-a-glance status indication of the unit. Additionally, two 8-position dip switches are located at the bottom of the unit to allow the configuration of various asynchronous or synchronous line rate settings.

  • Extends serial devices up to 5 miles (8 km) over ordinary grade twisted pair.
  • Miniature size for direct connections to your serial port.
  • 2B1Q modulation enhances signal immunity in noisy environments and increases the distance of RS-232 signals.
  • Multiple user-configurable asynchronous and synchronous rate options.
  • Transparently passes RS-232 control signals over the link.
  • Made in the USA — This Patton equipment is designed by Patton engineers and built in our Gaithersburg, Maryland facility. Patton's American-made manufacturing process delivers high-quality networking solutions with reliability you can trust.
