System Overview

2-15

Communications Interface

There is one communications interface on the WDG-V.

RS485 MODBUS RTU Configuration:

Two Wire

57.6 Kbaud

No Parity

1 Stop Bit

The WDG-V is configured, calibrated and monitored via the MODBUS
RTU interface. AMETEK provides two options for communicating with
the WDG-V:

• AMEVision Display User Interface (Reference separate manual)
• WDG-V Configurator Software via PC (Provided with each unit)

Since the interface is industry standard MODBUS, custom user software
can also be written. For this purpose, refer to Chapter 11 for the MODBUS
MAP or consult the factory for the MODBUS register definitions.
