3.5.6 Product Specifications

3.5.6.1 Monitoring Port Pin Assignments

The Monitoring port is a 9-pin communications port. The port operates with no flow control at a rate of 2400 baud. The data format is 8 data bits with 1 start bit, 1 stop bit, and no parity. When the Triple Chassis operates with simple signalling, the following limitations and capabilities apply to the Monitoring port:

•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 non- inductive load of 25 mA. Use only Pin 4 as the common.

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

•The UPS is signalled to shut down when a high RS-232 level is applied to Pin 1 for 4.5 seconds. Shutdown is also dependent on the UPS status.

When the Triple Chassis operates with advanced signaling, the following limitations and capabilities apply to the Monitoring port:

•Pin 7 is unassigned.

•DC operating voltage is available on Pin 8. This voltage may be from the UPS or from an external adapter.
