Hello,
Simply put, can the RF411 radios be used as an addressable, serial communications system between 3 devices, where two devices are PC, and one is a 'dumb' command response device?
Additional info:
I am wondering whether the PakBus protocol (or some other method) can be used to implement a simple 'mesh network' in which 2x Windows PCs each with a radio on a serial port could be used to share a connection to a simple RS232 device also with a radio attached.
In this application, either PC can decide to make a measurement at any time, but would check with the other PC first whether it can or not. For this I would require the PCs to be able to issue serial commands directly to each other without the serial device 'hearing' them. I would write some kind of negotiation protocol for this.
Then, once permission to measure has been granted/negotiated the PC with permission to use the RS232 device would then issue a series of command/response exchanges with that device. Ideally, responses would only be received by one PC, but that aspect is not crucial.
I understand this might require 'hi-jacking' pakbus system, or possibly using cora_script to push around packets.
...I think, I'm asking whether 3x unadressable RS232 devices can be networked together via radio, and assigned addresses...
Best Regards,
Steve
The RF411 is not well suited for the application you describe.
I suggest you look into the radio offerings from Digi. You will need to work out radio addressing and time division access to suit your needs.
The RF411 is using a Digi radio with an added processing board of our own design which makes it more efficient for Pakbus radio networks.
if you already own the radios, try using the transparent mode and reference the methods used for communicating between LN and CR10X (non-pakbus devices)
