E8491B IEEE-1394 PC Link to VXI, C-Size (FireWire)
This unit is a high-speed C-size device with Resource Manager and Slot 0 capability.
Its logical address is 0, therefore it is always the mainframe's Resource Manager and is typically installed in mainframe Slot 0.
The high speed is accomplished, in part, through the use of small signals (200mV) that are transmitted differentially over the twisted-pair wire set with controlled-impedance characteristics.
The differential signal provides high-noise immunity.
