X10: Discrete I/O
The Geo PMAC limit and flag circuits also give the flexibility to wire in standard 12V to 24V limits and
flags or wire in 5V level limits and flags on a channel basis. The default is set for the standard 12V to
24V inputs but if the resistor pack is added to the circuit, the card can read 5V inputs.

The Geo PMAC Drive limit and flag circuits also give the flexibility to wire in standard 12V to 24V
limits and flags or wire in 5V level limits and flags on a channel basis.
The default is set for the standard 12V to 24V inputs but if the resistor pack is added to the circuit, the
card can read 5V inputs.
If RP7 (limits 1) and RP8 (limits 2) are installed in the unit, the voltage level of the flags can be lowered
to 5V.

Position Compare Port Driver IC
As with the other PMAC controllers, the Geo drive has the high-speed position compare outputs allowing
the firing of an output based on position. This circuit will fire within 100 nsec of reaching the desired
position. The position compare output port on the Geo PMAC drive has driver IC at component U27A
and U27B. This IC gives a fast CMOS driver.
The following table lists the properties of each driver IC:
