front panel (the fault lamp is active regardless of this setting, if the
error messages are disabled (0) then the fault lamp will flash on and
off when a new error code is set). This setting is not retained through
a power cycle and defaults to 0 at power up. (only used for the pots
and meters display)

Front Panel Unit Configuration Password (code)
– 0 to 9999. This is
the code that needs to be entered from the front panel to access the
unit configuration menu. If the code is known it can also be changed
from the front panel within the unit configuration menu. The default
code from the factory is 0000. This serial command does not require
the existing code to be known, it is the responsibility of host
application to protect this password and keep in hidden if desired.

0,
Host port watch dog timer (WDT) time out. 0 to 65.535 seconds. A
value of zero disables the WDT. A non-zero value can be used to set
a time out window for valid host port communications. If valid host
port communications do not occur during this timeout window a fault is
set and operate mode is not allowed. Use this to prevent and abort
operate mode if host communications are lost. This would be used
when primary control of the power supply is from a host application
and it is not desired to allow operate mode if the host communications
are lost. If operate mode is active when host communications are lost
operate mode will be aborted and all channels will go into standby
mode, any timed cycles will be paused. Operate mode will not be
allowed until the host port communications are resolved or the WDT
time out value is changed to zero to disabl
e the WDT.
