The routerstation (not the pro version) works with 12v~24v (12v is kind common for alarm systems) and has 7 available GPIO pins (which works as inputs and outputs - you can connect relays, switches, leds, lcds, i2c and spi devices). > > GPIO pins can be easily controlled from userland with gpioctl(8) or with a small C program with the appropriate ioctl()s (or even using the led(4) framework). > > Please take a look at http://wiki.freebsd.org/FreeBSD/mips/UBNT-RouterStation for more detailed information. > > Both boards works _really_ fine with -current. > Hello, thanx, i see there is nothing GPIO related in 8.2, grep -i gpio /usr/src/sys/ yields nothing. Also, i was looking for an actual relay that could drive this simple wireless transmitter : http://www.visonic.com/Products/Wireless-Property-Protection/Universal-transmitter-mct-100 http://www.visonic.com/Data/Uploads/MCT_100_Installer_Guide_English_DE2241U.pdf (installation manual) So what i wanna do is simple, sent some command to a relay which will open a normally closed or close a normally open circuit in the above transmitter, and trigger an alarm. > Cheers, > Luiz -- Achilleas Mantzios
