UNID
The UNID command is used to set the units ID number. The Unit Id number is critical to remote
communications since it indicates to the unit which commands it should accept and respond to. Units are
typically shipped with a unit id of 1. If more than one unit is in the system and they will be communicated with
remotely the user must set a unique id in each unit. This can be done through the front panel interface, if one
exists, or by connecting to each unit individually and sending this command.
Setting:
1:1:UNID= 2\r\n ( unit 1, channel 1, New ID=2 )
Setting Response: 2:UNID:ok
NOTE: The new Unit Id becomes effective immediately
Query:
This command can be sent as a query but its usefulness is marginal being as it is a directed command and as
such it is necessary to include the Unit Id in the command and the response will simply validate the commands
unit id parameter.
Query Format: Unit#:Ch#:UNID?
Response format: Unit#:Cmd:Ch#:=unit id
Query: 2:1:UNID?
Query Response: 2:UNID:1=2;
