Connecting several displays or HMIs: Multi-display mode

Introduction

116
Multi-display mode allows a JC-120MC to be operated with up to four
alphanumeric displays and HMIs connected to one of the serial interfaces.
When doing so, the various HMIs display the same or different texts and/or
variable contents.
Connect the display or HMI via serial interface to X11. This port supports the
interface standard RS-422.
Irrespective of the fact that various hardware drivers have been implemented,
only one hardware interface is available.
This means:
While, for example, communication via RS-422 is taking place, simultaneous
and independent communication via RS-232 is not possible.
