Specifications

Basic port pin The following limitations and capabilities apply to the Basic

assignments ports of Share-UPS:

•Pins 3, 5, and 6 are open collector outputs which must be pulled up to a common referenced supply no greater than +40 Vdc. The transistors are capable of a maximum non-inductive load of 25 mAdc. Use only Pin 4 as the common.

•The output at Pin 2 generates a low-to- high RS-232level when the device is signaling an On Battery con- dition. The pin is normally at a low RS-232 level.

•Share-UPS may be signaled to shut down the UPS by applying a high RS-232 level to Pin 1 for 4.5 sec- onds. Shutdown is also dependent on the UPS status and the Share-UPS shutdown mode (see “Configur- ing Share-UPS,” on page 23).
