CS125 Present Weather Sensor

14.1 The SET command

The set command is used to configure the CS125 via the command line. The SET

command is a single space delimited string that can be sent from any data logger

or PC equipped with an RS232 or RS485 port. The SET command and the

‘Device Configuration Utility’ software access identical settings within the

CS125, please refer to the ‘Device Configuration Utility’ section of this document

for a more detailed breakdown of the setting available here. This command is used

to change the default power up state of the sensor. See Section 14.2 if a setting is

going to be changed on a regular basis e.g. heater controls.

See Section 12 for more information on the values used by the `SET’ command.
