Usage Examples

Communication Overview
To communicate with Nucomm equipment a standard ASCII byte-oriented packet is
used over an RS232 link.
RS232 settings:
BAUD: 9600 (Default) Unit is selectable
DATA: 8
STOP: 1
Flow: None
Packet outline:
<NU><Target address><source address><><Length><command><data>
<tt>Target address (00 – 99): This is the address of the unit. (Default = 01)
This is the address of the master controller. (Nucomm's controller uses 00).
Packet length (Range: 02-17 (Command Length + Data Length))
Command (00-FF)
Data (Hex Format)
<checksum> – (1's complement of <Target address> to end of data)
<CR> - Carriage Return
<LF> - Line Feed
In all examples shown the packets are as they would be displayed on an ASCII terminal
the "<> "'s has been added to the packet for visual delimiters only and do not appear on
the terminal.
A <01> is transmitted as a 2-digit ASCII code 30h and 31h.
