Each of the components of the packet is now explained.
A.4.1 START OF PACKET
Controller to Target: This is the character ‘<’ (ASCII code 60)
Target to Controller: This is the 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.
A.4.2 ADDRESS
Up to 9999 devices can be uniquely addressed. In both RS-232 and RS-485 applications, the
permissible range of values is 1 to 9999. It is programmed into a target unit using the remote
control port.
The BDC and BUC sub-devices may also be addressed by appending the corresponding sub-
device address. The sub-device address is ‘A1’ for the BXC.
For example, a mute command addressed to a BUC attached to an MBT-4000B at address 0412
will be:
<0412A1/MUT=1{CR}
