Remote Programming and Monitoring

Remote S/D and Interlock1	5–15 V signal or TTL-compatible output,
	selectable logic. TTL input impedance: 2 k
	(in series with one diode drop)
Remote Analog Programming (Full	Voltage and current programming inputs
Scale Input)	(source must be floating): 0-10 V voltage
	sources.
	Input impedance (V and I): 20 k
Remote Monitoring	Output voltage and current: 0-10 V
	Output impedance (V and I): approximately
	221 ohm; output short circuit current:
	approximately 20 mA (load must be floating)
Remote Programming and Monitoring	1% of full scale output for the default range
