Sensor extension

Hi Rob,

My robotank v2 hardware came with 6 sensor extension (3 optical and 3 no contact). I am having trouble setting up 3 no contact sensors. If you look at the screenshot attached, upper left corner i can only set up port 4, 5, and 6 which are optical sensors. It says Sensors 4 5 6. How can I set up no contact sensors? Where are the port 1, 2 and 3?

Hi @mytdbm I just checked and it's working for me unless I'm misunderstanding. Port 1, 2 and 3 are located on the controller, click the port where it's physically located and the settings will appear for it. When you click on "function" a drop down will appear where you can select the non-contact sensor. The reason port 4, 5 and 6 are on the side of the controller is that's where the sensor extension plugs in.

Ultimately it doesn't matter if you have it set as a float switch, optical sensor or non-contact, in the backend they are all handled the same, the only reason for the setting is to update the image on the dashboard so it matches what you're using.

I have 6 sensor extensions plugged in to the port on robo tank. But I only can set up 3 sensors on the app. As you can see sensor 4,5 and 6 ports are configurable. How can I set up the other 3 sensors on the extension?

Ah sorry, if you remove the lid you'll see some header pins that you add those black jumpers to. The board should be marked OPT for optical and NC for non-contact.

Sorry for my broken english. I think we are misunderstanding each other. Let me ask my question again.

Can I use all 6 sensors on the extension at the same time? If so, how can I set up in the up? It doesn’t matter what kind of sensor I use. I just don’t understand how to set them up in the app. Only 3 ports (port 4, 5, and 6) are configurable, but there are 6 sensors on the extension.

Oh ok, I understand now. That extension does have 6 ports however you can only use 3 of them. The reason it has 6 is because optical and non-contact sensors have different wiring and resistor requirements so I put a plug for each them to keep it plug and play. The jumpers inside the case enable one or the other port. In total you have 6 sensor ports, 3 on the controller and 3 on that extension.

Oh man. That makes sense. Sorry for taking so long to understand how it works. You are brilliant.
I have a quick question. On the V2 board, there are three sensor ports (port 1, 2, and 3), each with three pins. How can I connect a float switch that has only two pins to one of these three-pin ports? Additionally, I have some four-pin no-contact or optical sensors. How can I use those four-pin sensors with the three-pin ports?

I probably should have posted the manual to begin with. Here's the page that explains how port 1, 2 and 3 can be configured for each sensor type, at the bottom of the page is a table showing how to set the black jumpers. For optical sensors it's important to get the jumpers in place correctly before plugging them in otherwise they will be damaged.

I see I didn't mention float switches in the manual, those you can connect to the +5v pin and signal pin, then set the top 3pin jumper to P-D. The other jumpers aren't required for floats.
