Yes I 100% think there is a problem with the wiki. It doesn’t affect data from lowrance like depth, but if you like me and seems some others, want to feed GPS from PIX to lowrance, then if you follow the wiki - it will never work - and you won’t know that the wiring is wrong.
Per your other question, the right side pix wiring is actually correct (for the single use case above- eg depth ). For dual use case (eg depth into pix, and GPS from PIX into lowrance).
Yes I was fooled by this too. Usual practice and common sense says RX goes to TX. However I guess the RSD label means - “to RX” port on your device (eg PIX).
I have a RS232 to TTL adapter and it has the same “feature” confusing RX/TX labelling.
So for the YL-128 RS422 adapter
Lowrance cabling
Y - Green
Z - Orange
B - Yellow
A - Blue
When I get a chance, I’ll try to write up a simple guide for both RS422 and RS232 for bi directional comms with PIX / Lowrance. For bi directional comms, I needed to use 2 serial ports on PIX. I saw @rmackay9 previously talked about future feature using 1 serial port for 2 purpose, but I don’t think this exists yet ?
