Set Location(WL)
This function is provided as an alternate to using the DIP switches for
setting the unit’s Location/Address. If DIP Switch #7 is ON and #8 is
OFF, it allows the Location/Address value to be changed by the WL
command. This value is reported in the data record after the LOC tag.
The unit must be selected before this command can be used. If the unit
is the only powered instrument on the bus, the Universal (U) command
is appropriate. If other instruments are powered and are on the bus, the
device’s current address must be used to select it.
The change to the device’s Location/Address takes place immediately,
but the unit remains selected. It will continue to respond to commands
until the bus is readdressed.
For example, if a device is set to Location/Address 3 and any command
can be sent to it, then a
WL5
is sent, it will continue to respond to
subsequent commands even though its new Location/Address is 5 until
another device address is selected with the [ALT + ####] command.

WL d [CRLF]

function.

returned.
