Sending a command to a single unit
To send a command to a single unit when multiple units are connected, the
same procedure as for one-on-one communication is used.
1. Verify that all connected VM-83 units are set to local mode.
2. Send the RMT1**<CR><LF> command, where ** is the ID number of
the unit to be controlled.
3. Control the specified VM-83 unit by sending commands for changing
settings and getting information.
4. To switch control to another VM-83 unit, send the RMT0**<CR><LF>
command with the ID number of the currently controlled unit, to return
that unit to the local mode. Then send the RMT1**<CR><LF> command
with the ID number of the new unit, and repeat the above steps.
Note
Before switching control to a new VM-83 unit, always return
the currently controlled unit to the local mode first. If two or
more units are set to remote mode, output data will be mixed
up.
