3.3.9 Opto-Coupler Strapping
For each digital input there is a pair of Opto-coupler outputs indicating the status
of the alarm point. These opto-couplers are brought into a set of two connectors.
To enable the opto-coupler outputs, place the jumper labeled OPTO COPLR in
the ENB position.
3.3.10 User Interface
There are two 37-pin user connectors on the transmitter assembly marked J2
and J3. The signals from J2 and J3 are for local site status or connection to other
supervisory equipment such as the RMAS-120 UHF Radio Link equipment.
See Table 3.H
and
Table 3.I
for pin descriptions of the two user connectors at
the transmitter site.
