Interface
Use RS485, 9600, 8 bit data, 1
start bit, 1 stop bit, no parity. Idle between
bytes to be < 1ms. Delay between Packets
to be > 10ms.

Area Linking
The Base Area acts like an Area 0 for all
Channels that have that Base Area defined,
and is useful as a global control for a block
of Areas. The following is for the 24 Areas
directly above the Base Area, as used by
the Set Area Links and Clear Area Links
messages:
Byte 2 Bit 7 is the 1
st
Area, and Bit 0 is 8
th
Byte 4 Bit 7 is the 9
th
, and Bit 0 is the 16
th
Byte 5 Bit 7 is the 17
th
, and Bit 0 is the 24
