Set Remote Entry Mode.

0 = Local, 1=Serial, 2=Ethernet

Example: LRS=1
NOTE: The customer will always have query access when using serial and telnet. Also, the LRS

command is available in all modes as a means of acquiring control. The intent of this command is

Unit Alarm Mask MSK=

1 byte,

Value of 0, 1, 2

Command or Query.
Alarm mask conditions. If an alarm is masked, neither an alarm or a fault is set, and the user

will not know of a problem. Form of a, where:

0 = Alarm, 1 = Fault, 2 = Masked

a = External Reference Lock detect
The default value is 2
There could be a variable delay in the time it takes for the internal reference to lock to an

external reference, due warm-up characteristics and frequency differences between the

references. Therefore, the default setting is "masked" for the reference lock detect. This setting

may be changed if the customer so desires. The delay should be less than 1 s after 30 minutes

of warm-up time.

MSK?

MSK=a
