5.4.1
Start of Packet
The ‘
<
’ and ‘
>
’ characters indicate the start of packet. They may not appear anywhere else within the body of the message.
•
Controller to Target: This is the character ‘<’ (ASCII code 60)
•
Target to Controller: This is the character ‘>’ (ASCII code 62)
5.4.2
Address
Up to 9,999 devices can be uniquely addressed. In both EIA-232 and EIA-485 applications, the permissible range of values is 1 to 9999. It is
programmed into a target unit using the remote control port.
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.
5.4.3
Address Delimiter
This is the forward slash character:
/
(ASCII code 47)
5.4.4
Instruction Code
This is a three-character alphabetic sequence that identifies the subject of the message. Wherever possible, the instruction codes have been
chosen to have some significance – e.g.,
AMP
for RF Power Amplifier State,
ATT
for attenuation, etc. This aids in the readability of the message,
should it be displayed in its raw ASCII form. Upper case and lower case alphabetic characters may be used (A-Z, and a-z).
