F.2 Example of a 3 Datalogger Networking Session
1.
This session assumes that there are three dataloggers running at 60 second scan intervals.
2.
Press <ENTER> <ENTER> to wake the dataloggers from sleep. At this point, each
datalogger is “listening” for its network address to be transmitted down the RS-485 bus.
3.
To communicate with Datalogger number one and observe a reading type #1<ENTER>.
Datalogger
1
returns:
Network address: 1

*E
Note that the datalogger ID, which is the first entry for each ASCII character string, corresponds
to the network address.
This should be set by the user during initial datalogger setup via the
ID command
.
Typing E<ENTER> puts the datalogger back to sleep and disconnects it from the RS-485 bus.
The datalogger will continue to wake up periodically (scan rate setting) to take a data reading.
The E command must be used in order to disconnect from the current datalogger and
allow connection to the next datalogger
.
4.
To communicate with Datalogger number two and observe a reading, type <ENTER>
<ENTER> to wake the dataloggers and then type #2<ENTER>. Datalogger two returns:
Network address: 2

Doing the same for Datalogger number three results in:
Network address: 3
