Tracker 300 Configuration

You can configure the Tracker 300 series via the RS485 interface or by using a special PC to Tracker 300 cable, which plugs into the front panel "Config" socket. There are no internal links or potentiometers, so there is never any reason to open the unit. Each unit can be identified by a unique six character alpha numeric tag name, which is then stored in the instrument's memory.

Windows based PC software allows full configuration and calibration with setup files that can be named and stored for future use. You are able to print the Tracker configuration that is supplied with each unit prior to installation.
