The HDLC2000 is a four channel HDLC communications controller on a single PCI-104 card. The HDLC2000 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 HDLC2000 has been designed for demanding transportation and industrial applications. The HDLC2000 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 HDLC2000 is available with software drivers for Linux, Windows-XP/7/8.
