Installation Checklist
The following components are required for a complete A8332-8F2D I/O module installation:
● A8332-8F2D I/O module
● Screwdriver for terminals: 2.4mm slot/straight or equivalent.
● Obvius Configuration Console software.
● A computer with an RS232 or RS485 port and a serial cable, or a USB to serial adapter.
● Modbus/RTU master device such as an AcquiSuite™ A8812 server
● Pulse or analog output device
● Power supply: 24VDC
● Wire. Typically 18 to 24 gauge
3
for pulse or analog device connection.
● 2 wire, twisted pair with shield for Modbus/RS485 connection. (Belden 1120A or equivalent)
3
● Optional: Termination resistor (120 ohm) for long RS485 runs over 200ft.

Insulation connected to pulse meters inside high voltage panels should have an insulation rating in excess of the service
voltage. Consult a licensed electrician and local building codes for further requirements that may apply.
Configuration Software Required:
The A8332-8F2D requires configuration before it may be used. There are three primary ways to achieve this.
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://obvius.com. This manual makes a number of references to the OCC software. Installers are well advised to obtain a
copy of the OCC software prior to installing the A8332-8F2D on the jobsite.
2) AcquiSuite: Installers can use the Obvius AcquiSuite configuration web page to set up features in the A8332-8F2D.
3) 3rd party software or hardware/plc. If neither the OCC software or AcquiSuite are available, all features in the A8332-
8F2D may be configured by writing modbus register values to the device. Installers may use a software tool such as
ModScan32 or SimplyModbus to write to the registers. Also, many hardware data loggers or PLC systems can write to
Modbus registers as well. Complete modbus register information is available in this document in the “Modbus Register
setup” section for installers who wish to use 3
rd
party software or hardware to set up the A8332-8F2D.
