Target Address

In EIA‐232 applications, this value is set to 0000.

In EIA‐485 applications, the permissible range of values is 0001 to 9999.

Controller sends a packet with the designated Target Address, the Target responds to the Controller, using this
same address, to indicate the source of the packet.
