Buidling a RS232 PM9080 Fluke Optical Cable

[ZGoode]

Howdy y'all,
I'm working on building a copy of the Fluke RS232 optical cable for the scopemeters, but am running into some difficulties.  I started based off of the design by BVKSound, but haven't been able to get it to work.  Does anything look off in this design https://github.com/bvksound/Fluke_PM9080.  So far, it seems like the TX line isn't creating enough of a voltage difference, since when measured with my scope it only shows a 1V potential on the IR emitter.  Does anything look out of place or blatantly wrong in what I have here?

Well, I think I found one problem, but I still can't get it to work.  I think I flipped the RS232 connector around weird, but it still isn't working even after flipping it around with a cabled connector.  This should be easy, if I can get it to work on UART, I should be able to get it working with RS232
