I am developing a 12v UPS that I want to connect to the RB532 Serial Port so the Mikrotik sends an email when the power: GOES OFF, BATTERY IS LOW, POWER RETURNS

The UPS is designed to run the RB532 + 2 mPCI cards for about 35hours at average WLAN throughput

The microcontroller is a PIC16F877A including a status LCD


I understand that routeros supports the APC smart protocol, which I found some info on the web, but didn't really find it usefull/understandable

I have not managed to "trick" router os by sending data via the serial port from a PC (Null modem --> Hyperterm); Under UPS in Winbox the UPS status status remains OFFLINE

Does anyone know anything about the protocol or what values have to be sent via serial to the mikrotik. What I am after are just 3 states; On mains ; On battery ; battery low

I might also consider writing an ADC program to read the voltage from the battery and send that to the Mikrotik aswell

Once this project is complete I am willing to publish it including PCB's and PIC source code on the mikrotik WIKI page

Thanks

Hi Stanley

Welcome to the forum!

Your project sounds like just the kind of thing I've been wanting to build but I'm probably better at baking cakes than I am electronics (belive me my cakes are terrible)

Maybe this project may have useful information for you?

Hi Harvey and thanks for your reply

however the page http://www.apcupsd.org/ seems down

Good luck with your cakes!! and great job on the community wireless project!
