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:
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.
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

This specifies the number of rings during defined answer
hours. Valid entries for this register are 0-255 rings; an entry
of 0 rings will disable answering.
