Which model Gefen pattern generator?
thestumbler opened this issue · comments
Is this for the now-discontinued gtv-hdmi-siggen, or the current model gtb-hd-siggen?
I have the older model, so far no joy getting it to work. While I don't have the protocol, I have the correct baud and anything I send, the unit replies with "NG". I know it's otherwise connecting because I get this message at power-on: "TVSetting Reload!"
Hi!
For now, only the current gtb-hd-siggen protocol is implemented.
Is the old protocol published anywhere? Even if only partially available? I would be willing to add it.
Did you have a look to the user manual? I found the gtb-hd-siggen protocol in it.
Maybe you could also spy on the serial line while using the windows app and guess the protocol.
Good luck!
I have looked in the past at the UM and it didn't contain the protocol. I will double-check, and also I will have a look at what's published in the new model's UM. Maybe an email to Gefen would bring results, as based on your comment, they don't consider this information super-secret. And thanks for the idea of snooping on the serial port. I have a serial port anaylzer/logger somewhere around my lab, but I'm also pretty sure I can capture it entirely in software (my "Windows computer" runs in a VM on my Linux laptop). I'll keep you posted, and if it pans out, I'll start a branch to include the new(old) protocol.
