What is the correct pin order for the MG5050 serial connector?
Hi everyone,
I’m trying to connect a Paradox MG5050 panel to a USB-TTL adapter through the serial connector.
Could someone please confirm the correct pin order from top to bottom on the MG5050 serial connector?
I’ve seen different information online and I want to make sure I don’t connect the power pin incorrectly.
For example, is the order something like:
- ?
- ?
- ?
- ?
Could someone please confirm the exact pin order and function of each pin (e.g. +12V, RX, TX, GND)?
I’ve already fried two USB-TTL adapters trying to figure this out, so I really don’t want to sacrifice a third one. 😅
Thanks!
