Number
Description
1
Interlock Return – Common to chassis
2
Active Low Interlock – Connect to common (Interlock pin 2, or DB-37
pin 7 or 8) to enable.
6.4 Remote Control using the RS-232 Serial Interface
The RS-232 serial interface provides full remote control of the Auto Controller.
The Remote/Local select on the front panel must be used to set the unit to re-
mote to enable the remote control.
6.4.1 Interface cable
The interface cable for the Auto controller must be a straight through type
and must have a male DB-9 connector to connect to the female connector
on the rear panel of the Auto Controller.
6.4.2 Communication settings
The baud rate is 9600 b/s with 8 data bits, one stop bit and no parity. The
baud rate can be changed if desired. See the Auto controller setup docu-
ment in the appendix if another baud rate is required.
6.4.3 Communication overview
The acceptable command/response behavior for the Auto-Controller is
described below. The action/reaction of the Auto-Controller to commands
may be dependent on several factors or conditions, such as con
fi
guration
and current system states. These dependencies are outlined below for
each command/response category.
6.4.4 Commands, queries and responses
The auto controller can be con
fi
gured to use two types of cathode/neutral-
izers. The con
fi
guration described in this manual includes only those com-
mands that are used with the Hollow Cathode. Contact KRI for instructions
on con
fi
guring the auto controller for a cathode/neutralizer other than hol-
low cathode.
