Serial-based Remote Product Management
7.2.2.1
Start of Packet
•
Controller-to-Target: This is the character '<' (ASCII code 60).
•
Target-to-Controller: This is the character '>' (ASCII code 62).
The '<' and '>' characters indicate the start of packet. They may not appear anywhere else within the body of the message.
7.2.2.2
Target Address
Up to 9,999 devices can be uniquely addressed; in EIA-485 applications, the permissible range of values is 1 to 9999. The address is
programmed into a Target unit using the remote control port.
Each block converter module has its own address:
Module
MBT-5000
Block Converter A
Block Converter B
If several devices share an EIA-485 bus, it must be noted that the MBT-5000 will require three addresses, and should be spaced apart
accordingly.
The Controller sends a packet with the address of a Target – the destination of the packet. When the Target responds, the
address used is the same address, to indicate to the Controller the source of the packet. The Controller does not have its
own address.
7.2.2.3
Address Delimiter
This is the "forward slash" character '/ ' (ASCII code 47).
