Assign an Alias for the SEND Command
Use the SCOM command to assign a new command that works like the
SEND command. The standard SEND command of the transmitter will
always function normally whatever the SCOM definition may be.
Command names are case-insensitive.
SCOM
Example (assigning the command P as an alias for the SEND command):
>scom
Send command : ? p
>p
P= 1021.4 hPa T= 23.2 'C RH= 5.7 %RH
>
You can remove the SCOM definition by pressing Esc when entering the
command name:
>scom
Send command : p ?
>
Outputting Reading Once From All Transmitters
Use the DSEND command to output the reading once from all connected
transmitters that are in STOP or POLL modes. In order to avoid data
collisions, the transmitters will send their response after a suitable delay.
The response includes the transmitters’s address, followed by their
measurement message.
NOTE The total execution time of the DSEND command depends on the bit rate
of the serial port connection. At slow speeds, it will take a considerable
amount of time for devices with large address number to respond. The
delay will be the same even if there are no other devices at all.
DSEND
Example (transmitters with addresses 3 and 25 responding):
>dsend
3 P= 1021.4 hPa T= 23.2 'C RH= 5.7 %RH
25 P= 1021.3 hPa T= 21.2 'C RH= 8.2 %RH
