The BAIA converts digital inputs from the DSPX to analog outputs: channels A
and B are available for customer use at the terminal board; channels C and D are
used to drive panel meters. The BAIA provides an RS-232C I/O interface
between the DSPX and the drive's keypad and PC connections.
The BAIA board includes plug connectors to interface with other devices in the
IGCT drive. The BAIA board also includes adjustable hardware (jumpers),
testpoints, and LED indicators. The board contains no fuses. See Figure 1 for a board
