2.3.5 RS422 Interface
The RS422 interface is used for communication with a workstation. Three different protocols are
available which are described in chapter 4 on page 43.
NOTE
This interface may also be used for communication with a workstation via DDM-protocol.
However, no handshake signals are available. If the monitor has to be connected via RS422
interface with handshake signals, the RS232-2 interface has to be used with an external
interface converter (RS232 – RS422).
