Going from 100 to 150 pixels per port

[JSelph]

UPDATE:  Issue resolved! I was changing the number of pixels per string in the "Test" screen of the HU when I should have been doing it in the "Config" screen of the HU.  Doh!! I knew it was human error. Thanks everyone!

 

I'm stumped! What am I doing wrong?

 

I have a Pixie 4 and a Pixie 8 that I've been using the past 2 years. They have been running with 100 pixels per port. I want to add an additional 50 pixels to each port for a total of 150 pixels per port. I have gone into the Hardware Utility to set the nodes to 150 and when I test the lights, only the first 100 light up.  I have gone into the preview and changed the prop to have 150 nodes per string, double checked the starting and ending unit ID's, made sure the max circuit is set (it defaults to 510), and verified that there are no conflicts. But when I hook up the controller with lights and play the sequence, only the first 100 pixels are lighting up. I've created a new animation sequence and created a new prop....no difference. I've tried different ports, diffferent lights, even a different controller....and the same thing happens.

 

It has to be human error! What am I forgetting to do?

Did you configure the Pixie for 150 (with HU)?

Yes, but I just realized that I was setting it to 150 on the test screen and not on the configuration screen.  I think that may solve the issue. I'll let you know!
