I was wondering if the following scenario was possible.
A customer in New-Zealand doesn’t have cellphone reception in his fields.
So we can’t use 3/4G to get the correction signal.
He does however have a device that gives a correction signal via RS232 (UHF radio)
Does the following work?
UHF radio (Tx) connecting to Reach (Rx)
Our processing module (Rx) connecting to Reach (Tx)
And then connecting the grounds togheter.
Example with pin numbers:
UHF radio (Tx) connecting to Reach Pin 6
UHF Radio (Ground) connecting to Reach pin 1
Our processing module (Rx) connecting to Reach pin 7
Our processing module (Ground) connecting to Reach pin 2
Power supply (12+) connecting to Reach pin 9
Power supply (ground) connecting to Reach pin 3
The UHF radio can use the lemo port to allow the input of corrections to the reciever,…
Why not use the usb-c port or the Bluetooth to communicate to the processing module?
I am not sure I would hack 2 devices into the one rs232…
This setup should work fine.
Please note that with this pinout scheme, you’re going to power both the Reach and the radio from the power source.
If you’d like to power the radio from the Reach then you should change the scheme a bit.
You can split RS232 quite successfully on RTK streams from the radio is the comms is mono-directional. That why you only need two wires Tx —> Rx and signal ground. To get corrections via radio.
The issues crop up when more than one device wants to talk.
I’d be more concerned about the power split arrangements.
