MACID – Attribute 1
The MACID is set using two BCD rotary switches located on the front panel. Valid MACID addresses are 0 to
63 (0 to 3F Hex). Setting the switch address to a value greater than 63 will disable the switch and allow
software setting of the MACID. The software setting defaults to the last hardware setting. The switch is only
read during power up.
Baud Rate – Attribute 2
Settable only if the Baud Rate switch is set to a value greater than 2. Value returned will be switch value if
less than 4 or the last value set.
