6. REMOTE/AUTOMATED CONTROL
The Auto controller has a variety of remote control options available. These options
include a female DB-25 interface, A female DB-37 analog/digital interface and a
female DB-9 RS-232 serial interface. Note: The Auto Controller must be in Standby
to switch between local and remote operating modes.
6.1 Remote Control using the DB-25 Connector
The DB25 pin-out has been designed to be “drop in” compatible with the old
Mark II power supply to enable a minimum impact upgrade for the end user,
for a
fi
lament version only. With the hollow cathode version, only the remote
enable pins 7 and 20 are active. When using the remote enable, the programs
are entered and stored using the front panel as described in Operation sections
4 and 5 of this manual. After the programs have been acquired using the front
panel, switch the front panel from local to remote. Connect pin 7 (Beam on) to
pin 20 (Beam on return) on the rear panel DB-25 connector to enable the pro-
gram selected from the front panel.
6.2 Remote Control using the DB-37 Connector
The DB-37 connector is an extended control set which gives the operator full
access to the Auto Controller inputs and outputs. There are two main options
when using the DB-37 connector for remote control of the Auto Controller. One
option is to enable one of the four programs stored in the auto controller. These
programs can be acquired using the front panel as described in the opera-
tion sections 4 and 5 of this manual. The other option is to input the desired
operating parameters and then use the Auto Controller for sequencing and/or
automatic feedback to keep the discharge parameters constant.
If the DB-37
connector is to be used as a remote interface, then pin 18 (DB-37 Select)
must be connected to common pin 7 or 8 on the DB-37 for all the options
described below.
6.2.1 Remote Enable of the Four Stored Programs using the
DB-37 Connector
The DB-37 I/O allows program selection through the rear input ports. When
using remote enable, the programs can be acquired using the front panel
as described in Operation sections 4 and 5 of this manual.
Pins 16 (Program select 0) and pin 34 (Program select 1) on the rear panel
DB-37 connector are used to select the four programs. Making connections
to common pin 7 or leaving the connections open as indicated below in
