There are three digital inputs and one output available per
guide for remote control and signaling functions. The digital
inputs allow control of the following modes for each guide:
External Lock, Automatic and Manual. The digital output is
initially configured as an alarm for Loss of Null for each guide.
See Table 3 and Table 4 for the default configurations.
Refer to Figure 14 and Figure 15 for the controller connections
and the parallel I/O cable drawing 220601.
Note: To ensure that a command is properly executed, all
pertinent inputs for each command must be switched high or
low within 20 ms of each other and maintained for at least
30 ms.
