Convey rs485 between two Raspberry Pi 2? Can it be done?

Submitted by dennisdunbar on #1

Any idea how to do it? I need to move a 9600 baud data stream from one place to another. I have RS485 to USB devices and it does recognize the one at the server. How to get the client on a second Pi 2?

Thanks

Yes it can be done, you just need to run the virtualhere client for armhf processors on the other raspberry pi.

If you have a gui on the client raspberry pi you can use this https://www.virtualhere.com/sites/default/files/usbclient/vhuirarmhf

if you dont have a gui, you need to run the console version for armhf here https://www.virtualhere.com/sites/default/files/usbclient/vhclientarmhf and follow these instructions https://www.virtualhere.com/linux_console

If you dont have the usbip driver (take a look in syslog if the client wont start and it will show the reason), i can compile one for you and the virtualhere client will automatically download it. You need to provide the kernel version and i can compile one for you..

Ok so the client has a GUI, Rasparian on a Pi Model 2. I down loaded vhuiramhf but do I expand it or how to configure an launch?

just open a terminal in your raspbian desktop and type sudo ./vhuirarmhf and it will show the client dialog, then right click on the RS485 and select use.
