I am wanting to sound alarms for secondary dispatch(911 calls). We receive call information through email and will use Microsoft Outlook to make a rule to print the message and activate a relay through usb(an idea) to sound external alarms through-out the fire stations. Does this sound like it will work with the Super4 USB Relay Module, if so, how difficult will it be to setup programming?

A. 
The Microsoft outlook rule can be set to 'start application', if the email meets the specified criteria.

 

The application that is started can be a batch file called 'sound_alarm.bat' with the following line in it:
c:\program files\tctec\relayset.exe -salarm,01 -t10000

The above example will switch on relay one, of the relay board called 'alarm' for 10 seconds.
In this case, relayset.exe is located in C:\program files\tctec\ 

I tested this example on Microsoft outlook 2007.
Let me know if I can help further.

Question about the Super4.  Does the board/switch hold it's state during a power disconnect. For example:
Port 1 = On
Port 2 = Off
Port 3 = On
Port 4 = On

Will these states remain when power is disconnected from the board or will we need to manage the state after accidental power disconnects?

A.
The relays are non-latching, so when power is lost they default to the off (open) position.
The C source code for lrelayset.exe is on our webstite http://www.emx.net.au/page426.htm
It uses the ftdi linux library:http: libftd2xx.so
Alternatively,rather than use the libftd2xx.so library,  a compilable C - library is available to interface the FT232RL chip directly. http://www.intra2net.com/en/developer/libftdi/
This has been used to control the super4 under Debian for example.
Note: The super4 uses the FT232RL serial to USB converter in 'bit-bang' mode.

 

Please let me know if I you any further questions,
