6.5.1 Datex-Ohmeda enhanced pulse oximetry components (N-XOSAT option)

The Datex-Ohmeda enhanced pulse oximetry option (N-XOSAT) consists of the following parts:
• Sensor connector board and cable assembly
• Datex-Ohmeda pulse oximetry board (OSAT board)
• SpO
The measured SpO
board/cable assembly to the pulse oximetry board, then transferred to the SpO
Communication between the pulse oximetry board and the SpO
an RS-232C serial interface. The SpO
module bus of the monitor through an RS485 serial interface.
Serial communications connector
The OSAT board includes a bi-directional (2-wire) serial communications port. The serial interface
connector is a 14-pin, dual row header. The pin assignments are shown below.
