Do I need to know which connector is on the side of solarwinds? I already have the configuration done on the Iseries side
The Security Event Manager doesn't have a connector for Comtek /400.
You can check the listed of supported connectors here: https://documentation.solarwinds.com/en/Success_Center/SEM/Content/Connectors/sem-connectors.htm
If you need a connect created you can put in a feature request for one: https://thwack.solarwinds.com/t5/SEM-Feature-Requests/idb-p/sem-feature-requests
