Introduction

Welcome to the command user manual of the AUDAC SMA & SMQ amplifiers. For more

info about the SMA and SMQ amplifiers, see the corresponding user manual. This manual

only describes the use of the commands for controlling the amplifiers through RS-232.

Input list

1 Input 1

2 Input 2

3 Input 3 (Only SMQ)

4 Input 4 (Only SMQ)

Output list

1 Output 1

2 Output 2

3 Output 3 (Only SMQ)

4 Output 4 (Only SMQ)

Using the commands

The SMA and SMQ amplifiers have an RS-232 communication port which can control the

standard operation functions of the amplifier as further described in this manual.

It must be configured with 19200 baud, 8 data bits, 1 stop bit, no parity

Command overview

Example: Set volume output 1 to -30dB

ASCII: #|Q001|web|SV01|30|U|return

HEX: 237C513030317C5765627C535630317C33307C313262317C0D0A

Important:

- The address of the SMA or SMQ is fixed at Q001.

- The checksum is CRC-16 excluding the ‘#’. You can replace the checksum with

‘U’, this is always accepted as checksum.

- return = 0x0d 0x0a

- source address has a maximum length of 4 characters and cannot contain “|” or

“#”

Command flow

1) The client sends a command to the SMA or SMQ

2) The SMA or SMQ acknowledges the command by returning the same command and a

‘+’ as Argument.

3) The SMA or SMQ updates all client’s with the new information

All volume and routing settings are saved automatically with every change and will

remain when the device is switched off.
