5-9-2 External ECG/Respiratory Interface
5-9-2-1 Overview
Connections to the external monitor are illustrated in Figure 5-33, below.
The External ECG/Respiratory Interface module has a maximum 2Vpp (Volt peak-to-peak) input with a
maximum frequency of 100Hz. The inputs are differential.
There are three optional connections for the External Respiratory interface (refer to Figure 5-34),
depending on the Respiratory Monitor output type being used, as follows:
• Option 1 - Monitor with single-ended Positive output
- Connect the "signal" lead to pin 2 on the connector
- Connect the ground shielding to pins 5 and 7 on the connector
• Option 2 - Monitor with single-ended Negative output
- Connect the "signal" lead to pin 5 on the connector
- Connect the ground shielding to pins 2 and 7 on the connector
• Option 3 - Monitor with Differential output
- Connect the positive "signal" lead to pin 2 on the connector
- Connect the negative "signal" lead to pin 5 on the connector
- Connect the ground shielding to pin 7 on the connector
