CompactPCI  Dual Intelligent CAN Controller

CAN 2.0B comes with i960 processor for superior performance

The CX1-BAND is a CompactPCI® based, intelligent fieldbus controller with two independent CAN (Controller Area Network) ports.

The 3U Eurocard is provided with the i960RP/D (Intel) microprocessor, a powerful 32 bit machine giving freedom for any local data sampling and preprocessing. With its 8MB DRAM and 4MB Flash, the CX1-BAND offers a generous amount of memory.

Two SJA1000 (Philips) act as CAN controllers, incorporating all common protocol levels up to the latest version 2.0B. Both physical transceivers (PCA82C251) are optically isolated between themselves and the remaining circuitry. Each CAN port has its own connector (9-pole D-Sub, wiring according CiA Draft 102).

An additional UART (RS232) can be used as a general communications port, hence simplifying development and testing of on-board firmware, and allowing stand-alone operation of the CX1-BAND.

The CAN connectors CP1 and CP2 protrude through the boards front panel. Two push buttons for reset and NMI are indent mounted in order to prevent from being used inadvertently. A dual LED display reflects the board status.

The serial port SP1 is available from a dual row 2x5 pin PCB receptacle. When using a flat microribbon cable with a 10-pole IDC header on the one end and a 9-pole D-Sub connector on the other, the result is a PC compatible RS232 serial interface port.

Front panel adapter CR9-ADAPT The CX1-BAND is a 3U type (single size) Eurocard. For use of the CX1-BAND with 6U CPCI Systems, a mechanical kit is available which expands the 3U front panel to 6U (CR9-ADAPT).
