6.6 Communication parameters
The device allows the coniguration of the parameters listed in the following table.
The parameters marked with the symbol D are the default values.
Settings remain active even after the device has been turned off and they are stored in non-volatile memory.
RS232 BAUD RATE
Communication speed of the serial interface:
1200 9600 57600
2400 19200 115200 D
4800 38400
This parameter is valid only for VKP80III LAT and VKP80III REAR with serial interface.
RS232 DATA LENGTH
Number of bit used for characters encoding:
7 bits/car
8 bits/car
D
This parameter is valid only for VKP80III LAT and VKP80III REAR with serial interface.
RS232 PARITY
Bit for the parity control of the serial interface:
None D = parity bit omitted
Even = even value for parity bit
Odd = odd value for parity bit
This parameter is valid only for VKP80III LAT and VKP80III REAR with serial interface.
RS232 HANDSHAKING Handshaking:
XON/XOFF = software handshaking
Hardware
D = hardware handshaking (CTS/RTS)
This parameter is valid only for VKP80III LAT and VKP80III REAR with serial interface.
NOTE:
When the receive buffer is full, if handshaking is set to XON/XOFF, the device sends
the XOFF (0x13) on the serial port. When the receive buffer has cleared once again, if
handshaking is set to XON/XOFF, the device sends the XON (0x11) on the serial port.
BUSY CONDITION Activation mode for Busy signal:
OffLine/ RXFull = Busy signal is activated when the device is both in OffLine status and
the buffer is full
RXFull D = Busy signal is activated when the buffer is full
This parameter is valid only for VKP80III LAT and VKP80III REAR with serial interface.
USB ADDRESS NUMBER
Numerical address code for the univocal identiication of the USB device (in case of more
than a USB device connected with the same PC):
0 D 2 4 6 8
1 3 5 7 9
