Hello dear friends. Today i want to show you how to make a programing cable for CODAN NGT Series. All Codans of NGT Series has 3.5 mm female stereo jack connector, bottom side of Handset. it's a RS-232 Programing port. Not need any converter or Programing interface. Why spend money in just cable with two connectors when you can make it with yourself and price be a very cheap.
Let's go, For cable what you need is next:
1) DB-9 female connector
2) Stereo audio cable with shield (I used a 2 meters lenght)
3) audio 3.5 mm stereo Jack connector
Circuit looks like this:
The handset has Programming port on the bottom side:
Just connect your handmade cable between handset and PC and Program it!
Best Wishes
