PA10 line is output- and the WATCH DOG OUTPUT
OPTIONS, GOODLO output jumpered to OUT, RESHI output
jumpered to BUS. The source cards have UDN2984 and the sink
cards have ULN2803 chips installed. See Figure 4-1.

power the output drivers and the isolated side of the Opto

un-regulated power source, input range 17.5 - 35 Volts. The
power supply input is reverse polarity protected.
