Data
The TX Data frame from above is dissected below
First two bytes (3A 03 ) = System Address
Next 1 to 5 bytes (dynamic) = Unit Address and any repeater addresses. As
the message gets passed to the next address the address gets 128dec
(80hex) added to it which shows the message has passed through the
repeater or been received and acknowledged. You can see in the above
table the fourth byte of the transmitted message shows 02 which changes
to 82 on the received message and indicates the acknowledgment back
from the receiving module.
fifth byte (00) = Zero Byte spacer
sixth byte (86) = Frame Flag
– Type of message
The rest shows the message count and values.
