As specification indicates, your application should act as the host node with address in
between 0x00 and 0x0F.This ID is used to communicate with CTUs. The default address
for each CTU is 0xEF.
Predefined special addresses :
·
0xFF all nodes (hosts and CTUs)
·
0xF0 all hosts
·
0xF1 all CTUs
Identify Unit:
The first thing is to identify the CTUs in the network. As it was mentioned, all CTUs
have the default address 0xEF. If you have multiple CTUs in the same network, you will
need to first identify all CTUs and then change their address if needed.
Identification can be done with Identify message. When host application starts, the
default address 0xEFshould be sent with the broadcast address as the destination (see
Request below). For just CTUs you can use 0xF1 as the destination, which will return
serial number of CTUs. The destination ID 0xFF will return serial numbers of all the
hosts and CTUs . When CTU is powered, it will also send identify response message.
