I'm using an Arduino Uno to automate an RFID experiment for the lab I work for. This is my first time working with Arduino and I am having trouble connection the board to the RFID reader my lab got for the project ( the devices datasheet). the datasheet is very informative but I lack the experience and knowledge to know how to use it in code.
it uses a simple TTL level RS232 interface but I just cannot get it to work even with code that works fine for the other UART devices (it does work when connected to a windows app created by the manufacturer, so it's not just malfunctioning). it have a CTS line but not an RTS line and no example code I could find managed to establish a handshake . I have no doubt this is a very simple matter, but I'm very much a beginner and no information I reed about UART gave a solution.
the device's manufacturer and seller refused to offer any tech support beyond the information in the datasheet. I was told to "tick the hardware handshake enable box" but I don't know how to implement something like that in Arduino.
is there a library or an example that handles similar devices that can give me an idea on how this code should look like? a specific term I should read about? something I must use to make this work?
