6-2 Communication protocol
The available commands are of three categories:
•
Query COMMANDs
•
Setting COMMANDs
•
Operative COMMANDs
The commands have this format:
#00Qcommand(parameters)* where:
# = command string start
00 = string always present
Q = ? for query commands
S for setting commands
Command = command string
(parameters) = setting parameters value (where present)
* = command string end
At power ON the EP-600/601/602/603/604 is in Master mode, as
required by the communication with the hand-held unit 8053B; the EP-
600/601/602/603/604
will continue to send the measurement data
independent from receiving the commands. For this might be not
useful when interfacing to other software, send the command #00?v*
to turn the EP-600/601/602/603/604
in Slave mode to answer only
when receiving a query.
To save battery the EP-600/601/602/603/604
automatically turns off 180
seconds after receiving a command; use the operative command #00e
n* (see table 6-2) to set the time before the EP-600 auto-switches off.
