Hi wyn c, This is a serial USB to RS485 adapter for the computer. BACnet is a protocol, so your device converts this protocol to Ethernet (IP). I hope this helps you out. Regards, Garry
Hi Vijay, What are the errors that you are receiving? Did you install the software for your converter? roboindia.com/tutorials/CH340-usb-to-serial-driver-installation What communication port are you connected to? Regards, Garry
Hi Akshay Saraf, You can download this from the AdvancedHMI website. www.advancedhmi.com/ They can also direct you to download the version you want. What is not working? Have you followed the steps to build the project, add the communication and then test the project? accautomation.ca/create-a-plc-with-hmi-training-and-learning-environment-free/ Regards, Garry
I want to collect print output from an old DOS Computer that controls a measurement system Effectively removing the need for an old dot matrix printer. Any suggestion how to approach this task?
I would use a serial port logger. This link will list a few different ones. www.virtual-serial-port.org/articles/best-serial-data-logger-solutions/ I hope this helps you out. Regards, Garry
Hello Selvamani Mayadewan, The devices connected using RS485 are daisy-chained together. www.eng-tips.com/viewthread.cfm?qid=445810 This link will show you a picture of the wiring. Note: The shield of the wire is only connected to one end. Regards, Garry
