7.6.4 Programming the Digital Input
The digital input channels can be programmed for “active high” or “active low.” Active high indicates “alarm on the
presence of a ground signal” and active low indicates “alarm on the removal of a ground signal.” See the controller
software manual for detailed instruction on programming.
7.6.5 Analog Inputs
The analog input channels are used to monitor various types of electrical signals. Some of the analog channels are
reserved for specific signals, while others are designated as general-purpose inputs, which accommodate various
types of analog signals. The input cables should be bundled together and routed through the entry holes.
Default configurations and terminal numbers described below have been summarized in the drawings located at the
rear of this manual.
7.7 Network and Remote Communication
The system can be set up, monitored and tested via an Ethernet 10/100 Base-T serial data connection and ac-
cessed via the controller or a web interface. Pin-outs are shown in the customer connections drawing.
Some standard scenarios are described below:
• Network Connection: The Ethernet port is designed to connect the controller to a user supplied network (TCP/IP
supplied by the user) via a front panel RJ-45 jack. Use a standard network cable for this connection.
• Local Connection: The Ethernet port can also be used for local access such as using a laptop computer. Use a
standard Ethernet cable for this connection.
7.8 Connecting Battery Temperature Probes
1. Locate the battery temperature probes from the L-ADIO coiled below the distribution center.
2. Uncoil and connect the temperature probes to a battery termination post negative in each battery tray.
CAUTION!
Ensure that the correct polarity is used for all input cable terminations.

7.8.1 Load Distribution
Refer to guidelines supplied with the load equipment. Typically, distribution cables are sized to provide a 0.5V loop
drop at full load and meet the ampacity requirements of the protection fuse or circuit breaker.
