Introduction
The ready pin on the remote start connector on the GC is held low at all times
except when the GC, MS, and data system are all ready. On system ready, a logic
high of 5 VDC is present between that pin and any ground. This same high can be
detected between the ready and ground pins on the remote start connector on
the MS.
Start run input
The best way to generate a start run signal is to use the remote start connector
on the GC. Since remote start cables are made for most common devices, this is
often the simplest way. A general-purpose remote start cable that terminates in
spade lugs (Y-Remote Start/Stop, APG p/n G1530-61200), is also available.
Ensure that the system is actually ready before the start run signal is sent.
If necessary, the remote start connector on the back of the MS can be used to
send the start run signal. A contact closure between the start and ground pins
will start the run if the system is ready.
