PV- 5127: Power supply module with UPS

RS232

The PV-5127 has a connector (CN3, labelled “RS232”) that can be connected to an RS232 port on the CPU. The PV-5127 provides two handshake outputs with status information, and one handshake input for controlling shutdown. The RxD and TxD signals are not used, the only used signals are Ground and the three handshake signals. The three signals are compatible with the “simple signalling” or “basic signalling” protocol used by other UPS units.

The 10-pin connector, CN3 is designed to be used with a simple ribbon cable ending in a DB9 female connector to be plugged into a DB9 male RS232 connector on the CPU.
