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.

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.
