Remote Mode Operation
While in remote mode, use the interface commands to control the output
of the power supply from a computer. See “Operation” for a complete list
of device-dependent commands available with this interface.
From remote mode, change to local mode operation by pressing the front
panel LOCAL button or by sending either the GTL command or the
REN OFF command. You can disable the LOCAL button by using the
LLO command. For an example of how to use Local Lockout, see “Local
Lockout (LLO) Command” on page 2–23.
To return to remote mode, ensure that the REN command is set to ON and
then send any valid device-dependent command. Since the remote mode
output settings may be different from the local mode settings, the output is
programmed to protect the load by turning off when you toggle from local
to remote mode during a session. Check your remote settings and then
send OUT ON to restore the output.
