Prior Scientific ProScan III - OEM Commands

ProScan® III Manual
4.10 OEM Commands
The ProScan supports up to 6 filter wheels. These can be re-configured (by way of a plug
and play resistor) to behave as OEM stepper drives with either normally closed (type 24
resistor, 3K3ohm) or normally open (type 25 resistor, 3K9ohm) limit switches.
The command set is shown below. Step resolution will be dependent on motor type and
whether encoders are fitted. For a non encoded OEM axis typically this will be either
50000 or 100000 steps per revolution of the motor. For an encoded axis this will be
dependent on the nature of the encoder and driven axis.

OEM
n,P,x
0
Sets position of axis n to x steps
OEM
n,G,x
0
Drives the axis n to the absolute position x.
OEM
n,GV,v
0
Sets axis n moving at v steps per second.
OEM
n,K
0
Stops motion immediately on axis n.
OEM
n,$
m
Reports the motion status m of axis n:
0 = idle
1 = active
OEM
n,LMT
s
Reports the current limit switch state s:
0 = no active limit
1 = +ve limit active
2 = -ve limit active
3 = both limits active.
