External ECG/Respiratory Interface
5-9-2-1
Overview
Connections to the external monitor are illustrated in
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
),
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
