checked the Win7 settings as suggested and all appear correct. The Inbound rules is "Enabled" for both Dataxport and "Unitonics OPLC IDE". outbound rules does not list either, i do not know if this will be an issue or not.
when in Listen Mode and forcing a call, Dataxport closes abruptly with "Run-time error13; type mismatch". reopening and switching to Call mode and thru the schedule and/or a force call all works well.
incemeters "MB1 Connect to PC Request" and "MB2 Connect to PC" respond when in listen and the PB on the display is depressed. Incemeters "MB3 Disconnect" and "SB150 Ethernet Socket 3" do not respond.
