RS-232 Control
The SW41AB-V2 switch can be controlled via a 9-pin serial cable.
See page 10 for the full list of control protocols.
Details of RS-232 pin assignment and communication are below. Please note that depending on your control device
serial port pin configuration you may require either a ‘Straight’ RS-232 cable or ‘Null-modem’ type.

Commonly used Serial commands
There are several commands that are commonly used for control and testing:
STATUS Status will give feedback on switch such as zones on, type of connection etc
PON Power on
POFF Power o
OUTFRyy (where ‘yy’ is the input)
Example: OUTFR04 (this would switch the output to source input 4)
Common Mistakes
• Carriage return – some programs do not require the carriage return where as other will not work unless sent directly
aer the string. In the case of some Terminal soware the token <CR> is used to execute a carriage return. Depending
on the program you are using this token maybe dierent. Some other examples that other control systems deploy
include \r or 0D (in hex)
• Spaces – Blustream commands do not require space between commands unless specified. There may be some
programs that require spacing in order to work.
- How the string should look is as follows OUTFR03
- How the string may look if spaces are required: OUT{Space}FR{Space}03
• Baud rate or other serial protocol settings not correct - see above
