485 Serial Data Converter
Another accessory option available is the RS
-
485 conversion board. RS
-
485 is somewhat
similar to the RS
-
232 standard in that it is a wired transmissio
n line for serial data exchange.
The RS
-
485 standard offers several advantages over RS
-
232 in terms of cable length distance,
noise immunity, multi
-
node drops, etc.
