Patton Electronics Co. RS-232 to X.21 Converter Rack Card Model 2065RC

The Model 2065RC and 2066RC interface converter rack cards allow synchronous X.21 DCE hardware to communicate with synchronous RS-232 or V.35 hardware, respectively (the RS-232/V.35 interface is DCE/DTE switchable). Both units fit in Patton's rack chassis and ClusterBoxes™, and derive their timing from the X.21 DCE. The front card incorporates seven status LEDs, while the rear card presents two UD-26 connectors for hardware connection. Two Built-in 16-bit elastic buffers compensate for timing differences in data conversion.
