Setting the Switch/Voltage Mode Jumpers

The NXC-I/O10 responds to switch closures or voltage-level (high/low) changes. Compatible I/O devices include the Power Control Sensor (PCS), tape transports and limit switches. The inputs are set for SW mode (closure) or VO mode as described below.

SW (switch) Mode	Senses switch or relay contact closures or provides a logic-level
setting (default)	output. The 3-pin jumpers for each input should be set to SW before
(Jumper pins 2 and 3)	wiring inputs to the Card. An "On" condition is triggered by contact
	closures or a logic low of 0 to 1.5 VDC.
	An "Off" condition is triggered by a logic high of 2.5 to 5 VDC; set the
	associated I/O to switch mode. When used for an output, each I/O
	port acts as a switch to ground (GND), and is rated at 200 mA @ 12
	VDC.
VO (voltage) Mode	Senses high- and low-voltage states commonly from AC or DC
setting	signals. This mode provides opto-isolation. The 3-pin jumpers for
(Jumper pins 1 and 2)	each input should be set to VO (voltage mode) before wiring inputs to
	the Card.
	An "On" condition is triggered by DC levels from 2.5 to 28 VDC (+ or
	-), or AC levels from 2.5 to 24 VAC. An "Off" condition is triggered by
	DC levels from 0 to 1.5 VDC (+ or -) or AC levels from 0 to 1.5 VAC.
