3.13 Remote Output On/Off Control
Remote output on/off control may be accomplished by contact closure, or
through an opto-isolated interface with external voltage sources, AC/DC or
TTL/CMOS.
3.13.1 Remote Output ON/OFF by Contact Closure
Application of a contact closure between Pins J1-5 and J1-6 will enable the
output. See Figure 3-19 for connection requirements.

3.13.2 Remote Output ON/OFF Control by External Source
Application of AC/DC voltage between Pins J1-1 and J1-2, or TTL/CMOS
voltage between Pins J1-14 and J1-2, will turn on the power supply; this
interface is opto-isolated from circuit common, Pins J1-6 and J1-24. See
Figure 3-20 and Figure 3-21 for connection requirements.
