Hello,

I have a Digi ME9210 with the REal port sample and a dev board.

The Realport Software on Win7 can not find the device!!(40002549\_G)

The Digi Device Discovery in ESP can find the device!

Ping is ok.

I have checked all Troubleshooting-Tips!

Are you able to ping the unit from the Windows 7 host?

Make sure the 771 TCP port is not being fire-walled as it is the port used for RealPort communication. This can be tested using telnet:

telnet (IP\_of\_Digi Connect ME) 771

An error might give some clues on the problem.

Hello,

The port 771 is open!

When i connect the device manuell with the IP then the realport is working.

The setup wizard can not find the device!  
The ADDP Server is running on the device.

Only the Device Discovery in ESP can find the device!

Are settings in ADDP Server necessary that the Digi Realport Setup wizard can find the device?

It may be that the discovery port is being blocked (2362), this is commonly blocked by Windows firewall by default. If you need to be able to discover the device on your network, the following articles might prove helpful:

[http://knowledge.digi.com/articles/Knowledge\_Base\_Article/What-ports-are-used-with-Digi-s-Device-discovery-ADDP-protocol](http://knowledge.digi.com/articles/Knowledge_Base_Article/What-ports-are-used-with-Digi-s-Device-discovery-ADDP-protocol)

[http://knowledge.digi.com/articles/Knowledge\_Base\_Article/Device-Discovery-Troubleshooting-Tips](http://knowledge.digi.com/articles/Knowledge_Base_Article/Device-Discovery-Troubleshooting-Tips)

So long as you can input the IP when configuring RealPort, the discovery is not needed.
