B-5

RS-232 serial/analog interface cable—analog pinout

Use the Datex-Ohmeda

modem/analog

cable to connect an analog recording device

to the oximeter. Refer to

Parts list

in chapter 6.

The analog pinout is as follows:

RS 232

1

Pin 5 is used for signal ground
Pin 6 is used for analog output 1 (white jack, SpO

2

)

Pin 9 is used for analog output 2 (red jack, pulse rate)

Pins 1, 2, 3, 4, 7, and 8 are not used.

Connect the 9-pin connector on the modem/analog cable to the RS-232 connector
on the rear of the 3900/3900P, and connect the 3.5 mm white-cable jack (SpO

2

)

and the 3.5 mm red-cable jack (PR) to the recording device.

•

Jack tip carries the signal.

•

Jack base carries the signal ground.

Make sure the connections between the oximeter and the recording device are
secure.

To calibrate the recording device:

1.

On the oximeter’s front panel, press

and select SETTINGS.

2.

From the settings options, select ANALOG.
Use the +/– function key to cycle between the options (0.0V, 0.5V, and 1.0V).

3.

Select the voltage you want to calibrate on the recording device.
While at the settings screen, the selected voltage is then the only voltage
output through the analog channels.

4.

Verify on the recording device output that the voltage being sent is being
recorded correctly.

If it is not, follow the instructions that accompanied the recording device to
adjust it to the correct voltage.

5.

Repeat steps 3 and 4 to calibrate the other voltage.

6.

When calibration is complete, press

to return to the waveform screen.
