hi, in my current project which is data logging, i'm trying to transmit my data from my arduino datalogger to my computer via rs48 using a max485 chip and an FTDI rs485 to usb converter. The problem i've encountered here is that the data transmitted is not readable, just a sequence of gibberish that i cannot understand, ex: j@@$lu,o0vvee, something like that.
my max485 is connected in this manner: 1- no cannection 2- no connection 3- high (for transmit) 4- arduino TX 5-Gnd 6- A 7- B 8-Vcc
my FTDI rs485 to usb connection: just like in the data sheet.
i could really use some help in this.. thanks a lot. :)
