How can I connect teraranger evo 60m tower with pixhawk cube orange >

1

Hi,

How can I connect one teraranger evo 60m tower and two evo 60m ( TOP) and (BOTTOM) sensor ?
In total 10 evo sensors, already can 1 and can 2 are used, Telemetry 1 and 2 are also used so how can I configure the teraranger evo 60m tower and two teraranger 60m ( TOP and Bottom) using less serial ports as possible. Here are some pictures for connecting in other autopilot :-1

But the above pdf is for another pdf, I require for the pixhawk cube orange so please help me. Please help me with some visual diagrams.

You can assign Serial 4 (GPS2 port) for serial connection. If you are using CAN GPS, you can assign Serial3 (GPS1 port) for serial communication as well.

Can we use I2C spliiter or something else ? Can we increase the number of serial pins ? @Alvin

Hi @Alvin

These are few questions :-

  1. Could I connect teraranger evo 60m tower ( 8 sensors ) to GPS 1 port and another evo 60m bottom to it too ? Mean that both the sensors on one port ( GPS 1 ) ?

  2. Where is I21 on pixhawk cube orange ? Please attach some documentation for this. I am not able to get it. Which is serial 1, 2,3,4, etc ? Any docs ?

Yes if this I2C or CAN port.

Can we increase the number of serial pins ?

You can’t increase the number of hardware.

No. This is not how serial protocol works.

I2C1 is embedded in GPS1 port. This is written in The-Cube-Module-Overview

Hi @Alvin

Another few questions :-

  1. In which autopilot I can get more number of serial pins ?

  2. Suppose I use Can 1 for my here 3 gps. Can 2 with a splitter. In can 2 port of cube, the I2c splitter that comes with pixhawk cube orange is attached, and in that splitter, another gps ( Here 3 ) is attached along with rest three sensors that are ( Teraranger evo tower, teraranger evo 60m bottom and teraranger evo 60m top) ? Is this possible ? I mean can I connect the I2C splitter to the can 2 port, and in the spllitter, One here 3 gps, another three sensors (teraranger evo tower, teraranger evo 60m bottom and teraranger evo 60m top). So these all four things in I2C splitter ? Is it possible ?

For the serial pins, there is a standard from Ardupilot:
https://ardupilot.org/plane/docs/common-serial-options.html
where Cube modules gives only 5 serial ports
https://docs.cubepilot.org/user-guides/autopilot/the-cube-module-overview#i-o-ports
which concludes where are the serial ports for Cubes.
Notice that the ADSB will occupy serial 5 if you are using ADSB carrier board.

If you want the software serial/uart sequence, check the hwdef.dat in Ardupilot source code

Ignore this if you are not touching the software part, or else this will confuse you more.

For the splitter, this is possible. This is what it is used for. They only thing to concern is you may need to supply 5V to the CAN line separately, in case the sensors draw too much power.
