Communications Installation
To connect the unit to a modem using an RS-485 port:
Configuring Communication Ports (Parameters)
The 11 parameters listed are indexed to the two communication ports, unless otherwise
noted: An asterisk (*) identifies the preset value.
P770 Port Protocol
The communications protocol used between the HydroRanger 200 and other devices.
The HydroRanger 200 supports the Milltronics Dolphin format (see www.milltronics.com),
and the internationally recognized Modbus standard in both ASCII and RTU formats.
Other protocols are available with optional SmartLinx cards.
P771 Network Address
The unique identifier of the HydroRanger 200 on the network.
For devices connected with the Milltronics protocol, this parameter is ignored. For
devices connected with a serial Modbus slave protocol, this parameter is a number from
1-247. The network administrator must ensure that all devices on the network have
unique addresses. Do not use the value 0 for Modbus communications as this is the
broadcast address and is inappropriate for a slave device.
