IMPORTANT: Blustream Infrared products are all 5V and NOT compatible with alternative manufacturers Infrared solutions. When using third party 12V IR control solutions please use the Blustream IRCAB cable for IR conversion (12V to 5V) - sold separately.

Each Blustream HDMI product is supplied with the necessary IR hardware required:

IR Receiver - IRR

Blustream 5V IR receiver (supplied) to receive IR signal and control the SW41AB-V2

IR Control Cable - IRCAB

Blustream IR Control cable 3.5mm Mono to 3.5mm Stereo for linking third party control solutions to Blustream products.

Compatible with 12V IR third party products.

Note: Cable is directional as indicated - not supplied

EDID Control

EDID (Extended Display Identification Data) is a data structure that is used between a display and a source. This data is used by the source to find out what audio and video resolutions are supported by the display, from this information the source will discover what the best audio and video resolution that need to be output.

While the objective of EDID is to make connecting a digital display to a source a simple plug and play procedure, issues do arise when multiple displays or video matrix switching is introduced because of the increased number of variables.

By pre-determining the video resolution and audio format of the sources and display device you can reduce the time needed for EDID hand shaking thus making switching quicker and more reliable.

Configuration of the switcher EDID settings can be achieved using the product dip-switches on the SW41AB-V2. EDID dip-switch settings are shown below.

NOTE: You must power cycle the product aer making EDID changes. For some sources it may be necessary to power cycle the source, or switcher, aer EDID changes have been made for the source to update its video & audio output settings.

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
