MetPak RG Commands
MetPak RG
Polling for Data
The MetPak unit must be set for Message Mode Poll using MetSet software
(Comms Page).
A line of data will be output upon receipt of a ? followed by the Node ID (default Q).
It is recommended not to use letters A to F as these characters can appear in the checksum
in the data string.
Notes:-
In Polled mode the unit MUST be allowed 9.5 seconds after switch on to be
operational before the ? and Node letter are used to enable polling or it will
be missed.
When in polled mode, when data is requested allow 570 milli-seconds for the
unit to respond with a line of data.
If the MetPak RG detects a pressure/temperature/humidity sensor fault then
allow 4 seconds for an error data output.
Polled mode can only be used for point to point communications; it is not
possible to network units on to a common bus (except in SDI-12 mode).
