RST-5002 or RST-6001 Communicaon Module Wiring
The DCR-1006A can be connected to the RST-6001 RS-485-to-USB module for
interfacing with the APG Modbus soware, or to the RST-5002 internet commu-
nicaons module to provides remote access to the DCR’s readings and sengs.
The “RS-485 NET A and B terminals are the only connecon required for either
RST module.
Wiring the Switched Input for High/Low Level Backup
The DCR’s Switched Input can be connected to simple switching device, such as
a oat switch, to provide a high/low level backup and prevent dry pumping or
overow condions in the event of an ultrasonic sensor failure or malfuncon.
