Hello everyone,
Does anyone have a verified working wiring diagram or screenshot for the RJ11 to RS232 pinout on the Secure Premier 300 meter?
I’m specifically looking for a confirmed setup that has been tested successfully. Any reference images or pin mapping details would be greatly appreciated

Hi,

Please, don't try to make your own cable. The ready-made ones are cheap, and you will save a lot of time.
