Software House iSTAR Ultra - GCM LCD and USB Ports; AC Fail and Low Battery Inputs

General Control Module
17
LCD Contrast Potentiometer - RV1
Used to adjust the contrast of the LCD. Requires a 2 mm screwdriver.
USB Ports
Four Host Ports (Two Dual Ports) J8 and J9
 The ACM communications cables connect to these Ports. It does not matter
which Port is used as the ACMs are uniquely addressed using the USB 2.0
protocol.
AC Fail - Low Battery - J2
Figure 4 on page 17 shows AC Fail and Low Battery wiring. They are NC
(Normally Closed) connections, and share a common ground pin.

AC Fail Input
 Indicates whether the external power source has reported loss of its main
power.
 Shares the connector and Ground pin with Low Battery.
 Normally closed dry relay contacts are required. This signal is normally wired
to the energized NO (Normally Open) output on the apS.
 Configurable on the host as an unsupervised input, as with iSTAR eX, iSTAR
Edge, and iSTAR Pro.
Low Battery Input
 Indicates whether the external power source has reported its battery as low.
 Wired in from the external power source.
 Shares the connector and Ground pin with AC Fail.
 Normally closed dry relay contacts are required.
 Configured on the host as unsupervised input.
