The Compumotor 4000 can be used on either an RS-232 or GPIB interface. You
must program the RS-232 baud rate or the GPIB address using the Compumotor
front panel controls. You should consult the Compumotor manual for details,
but in brief, the procedure is as follows. You must first enter
the ACCESS code (the factory default is 4000). You then
choose the IMMED function, and then the DEFINE GPIB ADDR
statement to select the the GPIB address. Alternatively, choose the
IMMED function, and the the RS232 PORT1
or RS232 PORT2 statement to select the port and configure the
baud rate for the RS-232 interface.
There are many other configuration options with this controller. Other
than the GPIB address and the baud rate, you should probably not change any
of these others. You can reestablish the factory defaults using
the RESET function from the main menu.
Output pins 46 or 47 on the programmable output connector can be used
to gate a counter during powder-mode scans. While the powder-mode motor
is moving during these scans, spec sets pin 46 high and pin 47 low.
Use the one appropriate for your particular counter. To gate the
Ortec 994 counter/timer, for example, pin 46 and
an even-numbered pin (all are logic ground) are connected to the front
panel enable BNC connector on the Ortec module.
