Comment
This cable has an 8-pin M12 connector at one end and the other cable end is 'open'. There
are 8 color-coded single cores there for connecting to external devices. There are different
cable lengths in the product range (3 m to 50 m). Long cables can be reduced if necessary.
Note
For long cables: Adapt supply voltage and data rate accordingly
Note that with long cables in particular, the supply voltage of 24 V DC must always be applied.
Note also that the data rate on the serial interface must, if necessary, be reduced. (See
"Configuration Manual RF620R/RF630R")
