Fuji Electric PXG-9 - List of Setting Parameters

Chapter
The following settings are required for proper communication between the master and micro controller units.
• The communication parameters for the master and all of the units must be set the same.
• During RS-485 communication, all of the micro controllers on a circuit must be set with different "Station No. (STno)" other
than "0 (zero)". (Multiple micro controllers must not have the same "Station No.".)
• When using the PC loader interface, settings are not necessary on the main unit (the micro controller).
The setting parameters are shown in the chart shown below. Change the settings using the keys on the front of the micro
controller.
■ RS-485 (main unit side)
■ Loader interface (main unit side)
The parameters do not need to be set. Set the loader software (master) with the following settings.
• Communication speed: 9600 bps
• Parity: none
