I am stuck on a RS485 Problem and I am looking for some help.
Currently I have a sensor that outputs serial data to a 78971108 type chip then to 485 via a MAX485 down a pair of wires to an another MAX485, a 8051 and
as1108wl to drive and LED display
I want to build my own display. I was going to use a LASCAR DDM4, or DMX973B or a MDM-1 display. Obviously I require a MAX485 (Although a MDM-1 has an option to have one fitted), but I am confused as to what else I may require.
Which display would be best?
Do I need a 8051 or similar with these displays?
How to I work out what is being transmited by the RS485 in order to program a MCU or similar?
Is it possible to copy the code from one 8051 to another?
Thanks in advance,
