3.4.4.1 Start of Packet

 Controller-to-Target: This is ‘less-than’ the character '<' (ASCII code 60).

 Target-to-Controller: This is the ‘greater-than’ character '>' (ASCII code 62).

Because this is used to provide a reliable indication of the start of packet, these two characters may not appear anywhere else within the

body of the message.

3.4.4.2 Target Address

Up to 9,999 devices can be uniquely addressed. In EIA-232 applications, this value is set to 0. In EIA-485 applications, the permissible

range of values is 1 to 9999.
