2 INSTALLATION CHECKLIST
2.1 Configuration Software Required
The A8332 (Flex I/O Module) requires configuration before it may be used. This guide will cover two primary
ways to achieve this. (Consult A8332 manual for third party software or hardware integration.)
2.1.1
Obvius Configuration Console:
The Obvius Configuration Console (OCC) is a software application
designed to assist in the setup and commissioning of Obvius hardware products. The OCC software is
available for free download at http://www.obvius.com/Products/Configuration_Console.
2.1.2 Energy Monitoring Hub users may use the integrated web browser interface to set up and
configure the A8332 (Flex I/O).

2.2 Modbus Address
Before the Flex I/O can be used, select a Modbus address for the
Flex I/O. This address must be unique among all Modbus devices
in the system. The A8332 supports address 1 through 127.
Select an address, and set the DIP switches to match.
The sum of the value of the switches is the address. In the
example to the right, address 52 is set by placing switch 4, 16 and
32 to the on position.
Note: 4 + 16 + 32 = 52
3.1 Installation
3.1.1 Connect the power supply to the input terminals on the
A8332 module.
3.1.2 Attach the RS485 +, - and shield wires to the A8332 module.
Attach the other end of the RS485 line to the Modbus master
device, such as an EMB Hub. Be careful to observe polarity
on both ends of the RS485 connection. RS485 wiring runs
should be limited to 4000 ft.
