Evening all, hope you're well and enjoying the weather, however that may be in your particular post code!
I'm looking for a little assitance with remotely controlling a Sony camera through it's USB connection, but looping it all into existing RS485 architechture.
Essentially, a bunch of existing RS485 items are controlled and monitored remotely through a 300 metre cable. I could have run a USB cable alongside, which no, I couldn't, and hence the issue. There are two spare RS485 inputs on the slave side. I'd like to convert the Sony camera's USB data connection to RS485 in order that it can join this network through the spare connection and hence achieve full remote control of the camera, as if it we connected straight into a laptop.
At the master end, there is a spare connector where I can retrieve the RS485. Plan is to re-convert this to USB for plugging into laptop and hence mimic the remote control function for the camera was intended.
My time with the real unit will be limited to an extent, so I'm trying to mock it up to at least have the concept operating prior to approaching the real life system.
The mock-up / test spread I have is as follows.
Sony RX100V > USB CABLE > 1st RS485 CONVERTOR (LINK BELOW) > 3 way cable (A to A, B to B, GND to GND) > 2nd RS485 convertor > USB > LAPTOP (port software undetermined currently).
RS485 CONVERTOR
Some of the parts have arrived, just waiting for a cable that I can butcher to artificially feed the 5v that the camera is anticipating through USB, so it recognises that it's been plugged into something.
I'm not 100% green on such issues, played with modbus and RS232 at technician level but that was 20 years and many beers ago so really hoping for some guidance..! I'm back messing with such things so looking forward to getting back into it, with a little help.
Thanks for your help folks, much appreciated!
