8.4 Interface RS485
If specially ordered, the unit can be fitted at the works with an RS485 interface instead o
f
an RS232C interface. This enables several units (up to 16) to be networked with a PC via
a common two-wire connection. By allocating addresses to the individual ovens in the
SETUP submenu under the menu item ADRES, the networked ovens are assigned
unique number addresses. These can be used to call up the oven and programme it from
the PC.
For this type of connection the PC must either have an RS485 interface or be equipped
with an RS232/RS485 converter.
Wiring is arranged individually depending on the installation site ,using a shielded cable.
The maximum overall length of the line is 150 m
Example:
Four ovens networked via an RS485 interface.
