4. Carefully insert the cable, with nut, washer and seal into the
bottom of the sealing cable port housing and tighten the retaining
nut until the cable is secure.
To protect cable from slipping,
provide external strain relief at mounting point.
5. Connect the chosen wire pairs to the Connector Block and verify.
See Figure 2.2.
6. See Section 6.4.3 for additional mechanical information on wiring
to the terminal blocks.
7. See Section 2.7.4 for definitions of terminal connections and DIP
switch settings.

Signal Connections and Controls
Listed below are the meanings of the various connections on the
connector block, and configuration methods. Use this section, including
Figure 2.2, to identify and connect your chosen signal wires.
•
RS-232, COM1:
Connect to terminals, TxD, RxD and GND or
RJ11 Programming Port. Configurable only with dip switches;
positions are indicated in Table 2.1.
•
RS-232, COM2:
Connect to terminals, TxD, RxD and GND.
Configure using the 1095 Utility Application (see Section 4.2).
•
RS-485 (Transmit only):
Connection to RS485-A and RS485-B
only (half duplex).
•
Event Input:
Three input ranges: 5 – 12 Vdc, 24 – 48 Vdc, 120 –
240 Vdc, and RTN. Inputs are isolated. See Figure 2.2.
•
Inlet Power:
Two terminals, marked “+" and “–". Accepts 9 – 30
Vdc unregulated – reverse polarity protection.
•
Prog. Pulse A:
Two terminals, marked “+" and “–". TTL/
CMOS level shift output (0 – 5V).
•
Prog. Pulse B:
Two terminals, marked “+" and “–". TTL
CMOS level shift output (0 – 5V).
•
IRIG-B:
Two terminals, marked “+" and “–". TTL/CMOS level shift
output (0 – 5V).
•
IRIG-B MOD.:
Two terminals, marked “+" and “–". 1 kHz sinewave
at 4.5 Vpp, 3:1 AM modulation ratio. See Figure 2.2.
