jUPS 0.2

jUPS project is a Java class that implements MetaSystems 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 Minyards 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
Quickstart
For a quickstart download the tarball and have a look at jUPStest.java.
Enhancements:
- The creation of a jUPSCommand for an empty jUPSPacket was fixed.
