12 Option -JC24X
104 Jetter AG
12.5 Serial Interfaces
The integrated controller -JC24X has been equipped with two serial interfaces.
The first serial interface is an RS-232.
The second serial interface can either be used as an RS-232 or as an RS-422.
These interfaces can serve for communication between the -JC24X and the PC on
which the JetSym programming interface has been installed. Yet, they also serve as
a connection between the integrated controller and the HMI.
