Parameter 18 — MAC ID Switch Changed
This is a read-only parameter used to determine whether the Node Address switches have
been changed since the last power up. If the switches have been changed this bit will be set.
The default is 0 — No Changes.
Parameter 19 — Baud Rate Switch Changed
This is a read-only parameter used to determine whether the baud rate switch has been
changed since the last power up. If the switch has been changed this bit will be set. The
default is 0 — No Changes.
Parameter 20 — MAC ID Switch Value
This is a read-only parameter used to identify the physical setting on the Node Address
switches. This is helpful because the enclosure does not need to be opened. The default is 99.
Parameter 21 — Baud Rate Switch Value
This is a read-only parameter used to identify the physical setting on the baud rate switch.
This is helpful because the enclosure does not need to be opened. The default is 9.
