Connection
A maximum of four extended function keyboards can be connected to an
operator terminal. The first keyboard can be connected to the RS232C, RS422
or RS485 port on the operator terminal, independent of Point-to-Point or
multidrop configuration. The default setting is the RS232C port.
If more than one C-Key16 is connected to an operator terminal, the keyboards
are connected in an RS485 multidrop network. Connecting also the terminal in
the RS485 multidrop network gives the most efficient communication. Pass
through communication must be enabled in the extended keyboard connected
to the operator terminal, according to chapter
4.2 Function keys . Pass through
communication is only necessary when the first extended keyboard is connected
to the RS422 or the RS232C port on the operator terminal.
For connection to the RS232C port on the operator terminal, the cable CAB21
can be used. The maximum length of the cable is 15 meters.
The converter CAB8 (RS422/RS485) can be used for connection to the RS422
port.
For description of connections and cables, see chapter 7 Drawings .
