Multiple copies of PHD2


Sequence Generator Pro does not consistently use the selected port when attaching to PHD2.

Useful Info

Scenario: Running two independent copies of PHD2, configured using the -i option in PHD2. SGP configuration is set up with a specific port # (4400, 4401 for instance #2).

  • When refreshing the configurations, sometimes SGP seems to ignore the port and returns the list from the alternate PHD2.
  • It is possible for it to connect to the other (default) PHD2 instance if the #2 is not running. “Unsticking” this may require re-starting PHD2.

In order to make things work consistently, I usually will start the SGP for PHD2 #2 (4401), start PHD2 #2, refresh the list, make the connection, then open the SGP for PHD2 #1 and repeat.

It seems as though regardless of the port definition, if there is a PHD2 on port 4400, it tries to use that regardless of what the configuration says.

Yikes, clearly this is not something we considered in the initial implementation. Thanks for the report.
