The routerstation (not the pro version) wor= ks 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, swit= ches, leds, lcds, i2c and spi devices). >=20 > 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) f= ramework). >=20 > Please take a look at http://wiki.freebsd.org/FreeBSD/mips/UBNT-RouterSta= tion for more detailed information. >=20 > Both boards works _really_ fine with -current. >=20 Hello, thanx, i see there is nothing GPIO related in 8.2, grep -i gpio /usr/src/sys/ yiel= ds nothing. Also, i was looking for an actual relay that could drive this simple wirele= ss transmitter : http://www.visonic.com/Products/Wireless-Property-Protection/Universal-tran= smitter-mct-100 http://www.visonic.com/Data/Uploads/MCT_100_Installer_Guide_English_DE2241U= =2Epdf (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 alar= m. > Cheers, > Luiz =2D-=20 Achilleas Mantzios
