How do you modify the VK204-25 for TTL Levels?

Which solder pads need to be jumpered, if any?

Thank you for any info,

Kenny

1. Cut the pins where #1 is pointing at
2. Solder the two pads at #2

Once our new PCB revision is released, there will be no cutting involved!!!

Thanks Henry, will give it a try.

It makes sense to provide a jumper since not all of us use these things with computers

This unit LK/VK204-25 is one of the older units. They have been last on the upgrade path because they just worked so well

All the new units have a nice option for TTL now. It still may involve soldering but there will be nice little pads to do so.
