HDLC Communications Controller

The HDLC-PMC is a four channel HDLC communications controller on a single PMC card. The HDLC-PMC uses a high performance, industry standard serial communication controller to provide 4 independent channels that can be configured for either HDLC-Synchronous or Asynchronous communication.

The HDLC-PMC has been designed for demanding transportation and industrial applications. The HDLC-PMC supports an extended temperature operation range of –40 to +85C. All 4 ports feature galvanic isolation up to 2000Vrms.

Each of the 4 channels can be individually configured for RS-232, RS-422 or RS-485 electrical interface. Each channel has independent receive and transmit FIFOs that allow high speed serial data rates.

The HDLC-PMC is available with software drivers for Linux and Windows.
