PCM-ESCC-16

Description

The PCM-ESCC is a PC/104 dual channel, multiprotocol data communications controller based upon the Z85230 Enhanced SCC. Each serial channel is independent and capable of synchronous or asynchronous data communications with either RS-232 or optional RS-422/485 electrical levels. The module can be configured to satisfy a wide variety of serial communications applications and can be used to interface to a terminal, printer, modem, or other serial system peripherals.

Features

  • Two independent, full-duplex serial channels
  • Asynchronous and synchronous (BISYNC, SDLC, HDLC, and CCITT-X.25) protocols supported
  • RS-232 and optional RS-485/422 electrical interface levels on both channels
  • Asynchronous mode supported with:
    • 5-, 6-, 7-, or 8-bit character lengths
    • Even, odd, or no parity generation and checking
    • 1,1.5, or 2 stop bits
    • Break, overrun and framing error detection
  • Industrial -40° to +85°C operational temperature
