X - Auto Send from switch-on

The ‘A’ command is cancelled by any following commands and is not restored at switch-on. If the pressure transducer continuously sends readings and does so even after power failure, (this includes using the ‘shutdown’ facility) then the ‘X’ command can be used to select this facility. This command allows a transmission period to be stored in nonvolatile memory which will be automatically loaded and actioned as if the ‘A’ command had been sent at switch-on.

Command: X,nnnnnn

Where: ‘nnnnnn’ is a number between 0 and 999999.

This is the transmission interval in seconds as for the ‘A’ command. A value of 0 disables the Auto send at switch-on.

Reply: None

Result: Instrument powers up in auto-send mode with the selected transmission interval.
