Dear All I am trying to interface LAB instruments with LAB System using ASTM over TCP. I read the documentation [here ](https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=EAST). But I can't understand how to connect instrument and LAB system in same port, please see the screenshot of interface below. Please help. Details: * For Servece I use "EnsLib.EDI.ASTM.Service.TCPService" class. * For Proccess I use "EnsLib.MsgRouter.VDocRoutingEngine" class. * For Operation I use "EnsLib.EDI.ASTM.Operation.TCPOperation" class.   ![](/sites/default/files/inline/images/ens.png)
