jUPS project is a Java class that implements MetaSystem's Uninterruptible Power Supplies management protocol v1.12d.

It was successfully tested against:

Metasystem Megaline rack 2500

MetaSystem UPSes must be connected via a 3-wires serial cable to a PC where a serial-to-TCP tool must be installed

jUPS was written using Corey Minyard's ser2net acting as a bridge between the serial port and a TCP socket.

The UPS-PC serial cable pinout is:

UPS PC
9 pin 9 pin 25 pin
male female female

2 --------------------------- 2 ----------- 3
3 --------------------------- 3 ----------- 2
5 --------------------------- 5 ----------- 7

ser2net needs to be configured to bridge the serial port with 2400,8N1 parameters to a TCP socket.

A working ser2net.conf file is:

9999:raw:600:/dev/ttyS0:2400 NONE 1STOPBIT 8DATABITS -XONXOFF -RTSCTS -LOCAL

This setup forwards serial port /dev/ttyS0 (COM1) as 2400,8N1 to local TCP port 9999
