Continuous Data Output
The continuous data output mode continuously outputs measurement data approximately every
100ms.
Continuous data output is enabled by sending the following ASCII string to the gauge:
H<CR>
Continuous data output is disabled by sending the following ASCII string to the gauge:
I<CR>
where
<CR>
is the Carriage Return character.
When continuous data output mode is enabled, the gauge will continuously output measurement data
approximately every 100ms as an ASCII string formatted as follows:
$(Gauge type)(Diameter)(Status)(Position in gate)<CR><LF>(Units)(Axis)

OMMUNICATIONS
This RS-422 / RS-485 interface is fitted as standard. It operates independently of the other
communications interfaces and may be accessed at the same time as them.
RS-422 / RS-485 interface
The RS-422 / RS-485 interface may be accessed through the “RS232/485” connector.
