BARCODE & SERIAL No.
The barcode reader may be used for automatic product selection and / or logging of a serial
number with test results. The barcode scan may be used to start the test automatically. If the
barcode reader does not supply a serial number then a simple sequential serial number may
be generated by the FCO770. Note that if the serial number is to be provided by a barcode the
instrument will not start a new test until a serial number has been scanned.
Product or serial number information may be extracted from barcodes of up to 64 characters
in length. Larger barcodes may be scanned, but anything after the 64
th
character is discarded.
An ASCII Carriage Return character terminates the barcode.
Barcodes
STARTFC
and
RESETFC
may be used to start and reset the instrument.
Note that there is a Check Barcode utility available in the utilities menu that may be helpful
when configuring the barcode reader.

PORT
•
Note that a port might not be listed if the optional hardware is not fitted. Although all
ports are available for selection the barcode reader would usually be connected to the
RS232 port.
•
Options:
o
DISABLED:
The barcode reader is not available.
o
RS232:
Uses the 9 way D rear panel connector.
o
USB:
Uses the front panel connector. Note that this is unlikely to be useful
with barcode reader because the FCO770 is a USB
peripheral
device, however
it may be useful with a PC or PLC.
o
RS485:
(optional) uses the rear screw terminal connector.
o
LAN
: (optional) uses the local area network connector.
BAUD
•
The baud rate is the speed that data is sent via the serial ports. The baud rate must be
the same on the FCO770 and device being connected. When using the LAN the baud
rate must match the configuration of the LAN adaptor. This is not used for USB.
•
Options: 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200.
PARITY
•
Select the type of parity error checking used when sending data via the RS232, RS485
and LAN ports. Parity is not used for the USB port.
•
The parity setting must be the same on the FCO770 and device being used. When
using the LAN the parity must match the configuration of the LAN adaptor.
•
Options:
o
8,NONE:
8 data bits and no parity.
o
7,ODD:
7 data bits plus odd parity.
o
8,EVEN:
7 data bits plus even parity.
o
8,ODD:
8 data bits plus odd parity.
o
8,EVEN:
8 data bits plus even parity.
