I bought a RS232-to-Everything adapter. It has a female DB-9 connector.
I want to use the RS232-to-Everything adapter with a simpleRTK2Blite to feed NMEA position messages in to a an AG-leader Farming Display.
The Display has also a female DB-9 connector on its cable harness.
Can I use a simple gender changer like this:
Or do I need some kinde of null modem adapter?
Thanks in advance!
That’s a good point, we should sell a cable kit in our store
Null modem will depend on the RS232 configuration of you AG-leader, i’m afraid you will have to try…
Please keep us posted, we find this integration very interesting!
Tank you for replying. Ok I have to try, but is the RS232-to-Everything adapter DTE or DCE?
I think simple gender changer will do the trick.
I’ve used TTL to RS232 converters with simpleRTK2B boards to add RS232 connector for ag purposes. Then used simple serial cable between simpleRTK2B and ag terminals.

Ok, I’ll Try that
Summary of the experiences of feeding NMEA data from RS232-to-Everything adapter on a simpleRTK2Blite to a AgLeader InCommand display with Ontrack3 autosteering.
- Straight through gender changer adapter as shown in my first question did not work
- Null modem cable does not work either. The null modem cable I used was like this:
It blowed the fuses that feed power to the display. The reason is that pin number 4 on display DB9 plug carries 12V from the display and the null modem cable wil short this to the ground on pin number 6 on the RS232-to-Everythin adapter.
- The solution was to make my own null modem cable like this:
DB9 on AgLeader Display
DB9 on RS232-to-Everything-adapter
signal GND 5
power plug on RS232-to-Everything-adapter
It worked perfect, and it also supplied the RS232-to-Everything adapter and the simpleRTK2Blite with power.
It is also smart to take note of this forum thread.
The description of the cable I meade in my last post is impossible to understand, so here is a better image:
Thank you for your post. We have built a sample cable and we would like to send to you for test. If you could confirm you could test it for us we will be happy to send it to you this sample. Contact us at email@example.com
