ION 7500 / ION 7600 User’s Guide

Communications Setup

 

 

Once basic setup is performed (i.e. the PT/CT and Volts Mode settings), the meter operates properly. Typically there is no need to make further changes to the Power Meter module’s setup registers.

Communications Setup

Communication settings are typically configured when the ION meter is initially put into service. Each communications port on a meter is controlled by a single Communications module. The modules’ setup registers define the parameters used for each port, so parameters do vary according to the type of communications channel selected (i.e. RS-232, RS-485, Modem, Infrared, Ethernet).

The Communications modules control the following channels:

Module Name

Settings

 

 

Comm 1

Selectable RS-232 or RS-485 port on COM1

 

 

Comm 2

High-speed RS-485 port on COM2

 

 

Comm 3

IrDA optical (infrared) RS-485 port or optional internal modem on COM3

 

 

Ethernet

Optional 10Base-T or 10Base-FL Ethernet port

 

 

A communications channel must be configured before you can use ION software (i.e. Vista or Designer). Altering the settings of a channel that is in use causes a loss of communications with the meter.
