ES Explorer and MiniSAP

Is it possible to connect ES Explorer for .NET to MiniSAP (6.2)? I have tried various ports, without luck. It looked like the .NET Connector would allow you to connect to MiniSAP, but I can't find any docs for connecting ES Explorer v1.0 to MiniSAP.

i.e.:

http://<MiniSAP machine>:<port?>/ServicesRegistrySiService/ServiceRegistrySiPort
