I C is a two-wire, clocked, bi-directional, digital serial I/O bus that is used widely in
commercial and consumer electronic systems. A transceiver on the motherboard converts
data and control signals from the PC-104 bus to I
board and optional analog input circuitry.
This circuit monitors the +5V power supply during analyzer start-up and sets the analog
outputs, external digital I/O ports, and I
and the instrument software can establish control.
