TPMC821 INTERBUS Master Interface

Complete PMC INTERBUS Master Generation 4 (G4) Interface. A MC68332 local controller and the IPMS3 INTERBUS protocol controller are used as controlling units on board of the TPMC821 PMC module. The communication between the host CPU and the TPMC821 is handled via a 4 Kb dual port memory. The on board firmware running on the MC68332 is the original INTERBUS Master Generation 4 (G4) firmware from Phoenix Contact. Furthermore the TPMC821 provides a RS232 diagnostic port, the optically isolated INTERBUS interface and status LEDs.

A wide range of drivers is available: Linux, Integrity, QNX, VxWorks and Windows. All drivers - except the Windows drivers - are supplied as C source code.
