The physical components of the system include:
✔ APS Custom unit
✔ Transmitter
✔ Antenna
✔ DB9 Null Modem Cable
✔ DB9 Cable to Flying Leads
✔ DB9 to DB25 Modem Cable
To connect the unit, follow the steps below.
1. Connect the telephone line inputs. Line 1 is for Port 1 and must be connected
correctly to ensure successful system operation. Line 2 is for Port 2 used as
the second call handling port in higher traffic. Line 3 is for the outbound
port, Port 3, used for wide area and/or overhead paging.
NOTE: To ensure proper operation of the unit, the physical line connections
must match the information specified in the PCI database.
2. Connect the data cables to the unit and transmitter. The power LED on the
unit will be lit.
3. Optionally, connect one or more of the contact closure port pins to external
dry contact closure type switches. Please refer to the contact closure port pin
specification for proper connection (Figure 2-1). A closure between any contact
pin (1-8) and Common (pin 9) will cause that event to activate. For more
detailed information on contact closures, refer to section 3.2.5, Configuring
Contact Closure Event Scripts.
