ARIA COMMAND PROTOCOL DEFINITION
Document Scope
The ARIA A6600 unit is capable of receiving any command over its RS-232 interface that is available on the
remote control. This document defines those commands and the method used to communicate those commands.
Connection Specification
The A6600 will accept commands sent using a standard PC RS-232 interface at 9600 baud, no parity, eight data
bits and one stop bit (9600-8-N-1).
Message Definition
Each message will consist of:
- a 2-byte header defined as 0x16 0x39,
- 1 byte describing the number of command bytes contained in the packet,
- a sequence of 1-byte commands, and
- a 1-byte checksum field to verify the commands sent.
The checksum is calculated on the Command bytes only. It is a simple sum of the values truncated to the low
order byte.
Below is a typical packet:
Header (2) Length (1) Command (1) Command (1) Command (1) Checksum (1)
0x16 0x39 0x03 0x20 0x4B 0x3A 0xA4
(Values in Hex)
