25.2 Communication interface RS232C (option)
The oven is provided as standard with a serial communication interface RS232C according to
DIN 12 9001. Using this interface it is possible to control the oven from the PC and to produce reports. This
is done using the “Celsius 2007“ software.
For this purpose the oven has to be assigned a unique device address in sub-menu SETUP, option ADDRESS;
This is the address through which the PC communicates with the oven. The default setting is ADDRESS 0.
Using this address each oven can be addressed by the PC and programmed.
If several ovens are connected by the RS232C interface to one PC, each oven requires a corresponding
interface on the PC as well as a separate cable.
The maximum cable length is 15 m.
For connection of the oven to the PC there is a 9-pin connector on the back of the oven. The oven can be
connected to the PC using a screened interface cable. The screen has to be connected to the plug case. If
the serial interface is not being used, the cover supplied has to be fitted !
