I have an APC Smart-UPS 1500 (Model number SMT1500i)
So far, I've configured NUT on a Raspberry Pi 1 and connected via the USB port on the back of the UPS.
While this gives me the functionality I want, monitoring the UPS, it doesn't look very tidy and it requires an external 5v power supply.
Inside the SmartSlot is an edge connector that I believe provides the following pins:
- +12v
- GND
- +24v
- GND
- (unsure, possibly battery voltage output?)
- +5V
- (unsure *)
- (unsure *)
- Serial TX
- (unsure)
- RX enable?
- Serial RX
- Power on (trigger low)
- Power off (trigger low)
* I think these are for the environmental monitoring NMCs.
I'd like to use the internal connector to provide the GND, +5 and Serial RX/TX to the Raspberry Pi, this making the entire solution internal.
I'm hoping that the Serial protocol present on the Edge Connector is the same as used on the Serial port on the back of the UPS.
Measuring the SmartSlot dimensions shows that the Pi will fit inside with a low profile SD card adapter.
Next steps are to design a tray to hold the Pi and a small PCB with an edge connector.

That doesn't look that easy/normal..
Just watched this one today because i want to hook my SMT1500i and SMT2200i up to a device via serial or CAN https://www.youtube.com/watch?v=feCh_2NXf5U
