Each board is uniquely identified via its' serial number string, this can
be changed using TCTECs RelayMapper application, making replacement of
boards easy and programming simple to understand.
Enclosure
suggestions:
For
indoor low voltage applications, The Super4 fits inside Jaycar cat: JP6011
A sealed
polycarbonate enclosure in an appliance control application.
Using
20mm (22 mm hole) cable gland for the USB plug (fits a type-B plug). Use
cable glands of required size for other wiring (example shows 1 for input
cable and 1 for output cable).
All
glands facing down for water proofing and drainage. Board is tacked in

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,
Regards,
