Commands are to be sent to the unit via RS-232 using the following format:

<Argument> = 0x0d

<Byte> = 0x30,0x30

Status Byte:

Upon receiving the command and done, a single status byte will be transmitted

The format for the status byte is :

<Command> = 0x31,0x30,0x30

RS232-Interface Usage Details:

The RS-232 interface has a first-in-first-out (FIFO) buffer which will allow each commands to be

received in direct succession. Commands are executed in the order in which they are received with

approximately a 1/2 second delay between each command. If a longer string of commands is

necessary, a minimum of 1/2 second delay should be added before sending additional commands.

Example for sending a long string of commands:

[Command 1]

[Command 2]

[Command 3]

If receiving the errors data, a single status byte will be transmitted. The status byte is:

Rs232 = <ERR>

ASCII = <0x45,0x58,0x58>
