CYBACK
For this program the RS cable must be connected on the RS232 port of the J5
plug.
The transmission parameters must be programmed on the DNC with the same
values as for the test of the serial ports (see paragraph above). These same
values must be programmed on the PC.
If the transmission runs at 4800 baud, you can try to increase the transmission
speed at 9600 baud.
The RS 232 norm gives as limit 15m. By using a more important distance,
there is a risk of bad transmission and it will be necessary to diminue the
transmission speed.
Reminder: The transmission command can only be given from the side of the
PC.
To permit the serial transmission with CYBACK:
Pass to programming mode.
! Call the
TRANFER DNC <
–
> PC
page.
! Introduce
2
in the
TRANSFER
field.
! Press the
key.
The display indicates
STATUS RS232
.
Programming mode From this instant on, the DNC can receive data sent from the PC, provided
that the DNC is in programming mode.
In the other modes (auto, semi-auto or manual) the DNC doesn't respond, the
transmission is not accepted.
During the transmission the operator can leave the DNC on any page. It is not
necessary to display the transfer page.
The transfer mode remains memorized, even if the DNC is disconnected from
power supply. It has to be re-programmed if the mode has been changed (for
instance FLASH).
