Hi,
I am using a wireless modem with router as my point of ethernet connection in a remote monitoring application (no land-line) using the IO-204. I am not on-site to supervise the system and it must run automatically without long term dropouts. The problem is that every now and then the modem hangs and I loose connection and it does not auto-reconnect. I am not sure why but I know this can happen periodically even with land-line connected modem/routers. The simplest solution is to switch power to the modem/router off wait a minute then power on again. Wireless connection is re-established OK every time I have done this. My question is, what is the easiest way to have the system reboot itself without manual intervention? I have a microcontroller connected to one channel through a serial smart board and I can easily switch the power to the modem/router on and off using a pin on the micro connected to a MOSFET. One possible solution I have thought of is to use a serial web service API to request every 10 minutes the GMT time. If the reply is not received within a couple of minutes then the mico will power the system off then on again. Is this the best way to do it or is there a simpler solution?
Thanks
