RS485 Network Guidelines
The instrument uses RS485 as its main digital communications link. RS485 is often
used in an industrial setting as a small device network. There are some installation
guidelines to follow when configuring an RS485 network with this instrument. See the
Modbus and SDI-12 Reference Guide.

Communication Overview
The instrument can be programmed to use either Modbus or SDI-12. Modbus and SDI-
12 cannot be used at the same time. The protocol that is in use will block
communication of the other.
See the Aqua TROLL 400 Modbus and SDI-12 Reference Guide
for registers and programming information.
Prior to connecting the instrument to the controller, you must configure communication
settings using the Comm Kit Software and the Communication Device.
