FAGOR does NOT supply these cables. Nevertheless, these are the
connection diagrams. Note that the RS232/RS422 BE adapter may be
used to connect the RS-232 or RS-422 serial line with a VT panel from
ESA.
NOTE. The user is free to use this FAGOR adapter or not. But, it should be
used unless indicated otherwise because it makes the connection a lot
easier.
