# Serial port

The incubator is equipped with an RS232 serial port that can be used to read the measurements obtained by the incubator internal sensors.&#x20;

The incubator provides data collected from its temperature, relative humidity, CO2 concentration and O2 concentration (optional) sensors.

There is a solution to read these values using an S2 Heraeus node via S2GW but the S2s are obsolete and cannot be used for any new installations. Additionally, in this case these are the incubators own sensors so there is no real monitoring with independent equipment, it is only logging.

Remark: An accessory HERAline option can be employed to convert operating signals from the RS232 interface into analog signals (0...1 V or 4...20 mA) for use with third party alarm systems.
