- The following cable will link any standard PC joystick port to
- any American Power Conversion UPS computer interface. This has been tested
- on an APC 520ES model UPS and on two different joystick cards. If your
- joystick card has two ports, you can use either without reconfiguring
- the software. The joystick buttons used for monitoring the UPS
- are those of the primary joystick. If you wish to keep using a primary
- joystick on your system and still use this software, you will need to
- modify the cable and software appropriately (i.e. wire buttons 6 and 7
- instead, figure out new port values for line fail and low battery).

- Note: Due to the lack of output signals on the joystick port, the UPS

- not supported. One possibility involves the use of the PC speaker
- and some external circuitry... any takers ? - pascal@CAM.ORG
