#Deployment

##Building a standalone application on W32

You will need a number of things installed

• Python2.7
• PySide (pip install PySide)
• py2exe http://www.py2exe.org/
• pyserial http://pyserial.sourceforge.net/
• pywin32 http://sourceforge.net/projects/pywin32/files/pywin32/
• Microsoft Visual C++ 2008 Redistributable Package (9.0.21022.8) http://www.microsoft.com/en-us/download/details.aspx?id=29

Once everything is in place, run:

python.exe ./setup.py py2exe

This will

##Creating a hotkey application

This requires AutoHostKey

• Launch the Convert .ahk to .exe utility
• Select the DVImatrix848key.ahk script as Source
• Select dist/DVImatrix848key.exe as Destination
• Select media/DVImatrix848key.ico as the Custom Icon
• Click Convert

bundling it all up

• Move the dist folder to DVImatrix848
• ZIP it

#Technical information

##Gefen EXT-DVI-848 Documentation about the device can be found at http://www.gefen.com/pdf/EXT-DVI-848.pdf

The interesting parts (commands to control the device via the serial line) can be found in Appendix B.

###RS232 settings

• Bits per second: 19200
• Data bits: 8
• Parity: None
• Stop bits: 1
• Flow Control: None

###Switching Command (shortcut) The first character (capital letter, starting with A) indicates the output monitor. The second character (number, starting with 1) indicates the input device. E.g. to route input 5 to output monitor A, use:

A5

###Matrix Status Command (shortcut) The M or m command will return the current routing state.

###Routing Command (shortcut) This command sets the matrix routing state according to a preset routing state. First character is S or s, second character indicates the state that is set by function #PSASRS or #MSASRS

###Set Preset Routing State This function enables the user to determine up to 10 routing states to save in memory.

#PSASRS␣<ID>␣<inA>␣<inB>␣<inC>␣<inD>␣<inE>␣<inF>␣<inG>␣<inH>\r

<ID> names the routing state and is a number in the range 0..9, and <in*> defines the input route to the given monitor, and is a number in the range 1..8.

###Set Current Matrix As Routing State

#MSASRS␣<ID>\r
