Gocator 2000 Family

This chapter describes the RS-485 serial communication settings and message formats supported by

Gocator sensors.

Gocator’s serial communication is unidirectional (output only). While measurement values and decisions

can be transmitted to an RS-485 receiver, configuration and control operations must be performed

through the Gocator’s user interface or Ethernet Protocol.

Refer to the Specifications section (page 162) in this guide for cable pinout information.

Connection Settings

Gocator serial communication uses the following connection settings:
