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.
RS-422 serial line cable between a VT and several drives (without adap-
ter)
If the user chooses to use the RS232/RS422 BE adapter, the RS-422
serial line must be connected as instructed in the following section. This
chapter has already described all the details on this adapter as well as the
pinouts of its ends.
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.
NOTE. Only for MMC or CMC drives.
