The EDI URL changed in Uniprint 8.1.  Previously it was in this form:

http://server/PharosEdi/Pedi.asmx

 

The new form is:

http://server/PharosEdi/EdiService.asmx

 

Additionally, the pedi.wsdl file no longer exists.  The WSDL description of the service can be viewed through this URL:

http://server/PharosEdi/EdiService.asmx?wsdl

 

If your IMFP software does not allow you to specify an EDI URL, you may need to contact Pharos Support to obtain a newer version of the software.
