The FW-3x-PMC-400T is a triple (3 independent nodes) Mil1394b OHCI host adapter with a 32/64-bit, 33/66MHz PCI host interface in a PMC form factor. The FW-3x-PMC-400T integrates three IEEE-1394 nodes (channels) on to a single PCM host adapter card. Each of the available nine ports are isolated using AS5643/1 defined active transformers that provide guaranteed minimum signal amplitude.

For applications requiring high node/port count and transformer isolation such as Flight Control, Vehicle Management Systems, Mission Systems or Avionics Simulation Laboratories that connect to a cross point switch, the FW-3x-PMC-400T provides the ideal cost performance solution.
