RS-232 Control

The KD-MSA8X8 provides access to all functions when used with an RS-232 control system. 

Connection protocol is as follows:

Baud rate: 57600
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None

Key Digital provides a resource database for downloadable control modules at:  
www.keydigital.com/controlmain.aspx

The KD-MSA8X8 features AMX’s Device Discovery beacon.

When connected to qualifying AMX control systems via RS-232, the KD-MSA8X8 identifies itself so 
that the control system automatically loads the appropriate module.  This feature makes integrating 
into AMX RS-232 control systems incredibly simple.

The KD-MSA8X8 RS-232 cable pin out is as follows: 

RS-232 codes for the KD-MSA8X8

The commands are not case sensitive.  The command lines with spaces shown below are for easy 
recognition.  Spaces are not necessary when entering these command lines in the control system, 
though adding them for easy recognition will have no negative effect.

1. I/O Switching Set:

‘SP Oxx SI yy’

  (Oxx= the letter ‘O’ followed by the number Zero then xx)

xx = output select [01~08]
yy = input select [01~08]

Example:

 To set output 3 to input 7, issue the command line: ‘SPO03SI07’

Pin 2 – Transmit

Pin 3 – Recieve

Pin 5 – Ground

2. unit Address Set:

‘SP C A xx’

xx = the desired 2-digit unit address [00~99]. 00 is used for stand-alone configuration.

Example:

  To change the unit’s address to 2, issue the command line: ‘SPCA02’

3. IR Sensor Enable/Disable:

Enable: 

‘SP C IR E’

 

Example:

 To enable IR response for the unit, issue the command line: ‘SPCIRE’

Disable:

 ‘SP C IR D’

 

Example:

 To disable IR response for the unit, issue the command line: ‘SPCIRD’

4. Front Panel Button Enable/Disable:

Enable: 

‘SP C FB E’

 

Example:

 To enable front panel push button response for the unit, issue the command line: 

‘SPCFBE’
Disable: 

‘SP C FB D’ 

Example:

 To disable front panel push button response for the unit, issue the command line: 

‘SPCFBD’

5. Output Audio Mute/un-Mute: 

 

Mute: 

‘SP Oxx CM E’

 (Oxx= the letter ‘O’ followed by the number Zero then xx)

xx = output select [01~08] 

Example:

 To mute audio on output 2, issue the command line: ‘SPO02CME’

Un-Mute: 

‘SP Oxx CM D’

 (Oxx= the letter ‘O’ followed by the number Zero then xx)

‘xx’= output select [01~08] 

Example:

 To un-mute audio on output 5, issue the command line: ‘SPO05CMD’

6. All Outputs Mute/un-Mute: 

 

Mute: 

‘SP C CM E’

 

Example:

 To mute audio on all output channels, issue the command line: ‘SPCFBE’

Un-Mute: 

‘SP C CM D’

 

Example:

 To un-mute audio on all output channels, issue the command line: ‘SPCFBD’

7. Reset unit:

‘SP C DF

 

Example:

 To reset the unit to factory default, issue the command line: ‘SPCDF’

8. Output Status Query:

‘ST Oxx’

  (Oxx= the letter ‘O’ followed by the number Zero then xx)

‘xx’= output select [01~08]

Example:

 To issue a query for the current status of audio output 5, issue the command line: 

‘STO05’
