ESCON

A or B on the connector is the Tx?

I don't know what A - B are in accord with Tx - Rx , but tx is usually on the right. You can also enable the port and see which has light , that's transmitt.

Thank you. I dont have a power meter and actually I am preparing a panel for connecting ST to ESCON connectors. BTW, the A and B are marked on the ESCON Connector.
