• The values of attribute 1 and 2
are retrieved from NVRAM if
the front panel switches are set to
program mode; otherwise, the
value selected by the front panel
switch is reported.
• The set service of attribute 1 and 2
directly updates the value for these
attributes in NVRAM. When setting
the MAC ID, the device will auto-
matically reset. To update baud rate,
a manual hardware or software reset
has to be executed.
• The value of attributes 2 and 9 are
decoded as follows: 0=125Kb, 1=250Kb, 2=500Kb
