Using the Optional Barcode Reader
The optional G3494A USB Barcode Reader and G3494B
RS- 232 Barcode Reader accessories provide an easy way to
input configuration information when used with an Agilent
data system. The G3494B accessory uses RS- 232
communication and connects to the BCR/RA port on the back
of the GC. The G3494A accessory uses USB communications,
and connects to the data system PC.
Refer to your Agilent data system help for additional usage
details.
The barcode reader accessories can be used to input data
directly from labels on the new consumables into the data
system. The data system uses this part number information
to search its consumable parts catalogs to then populate
various configuration fields with the appropriate data for the
part.
Scannable data includes part numbers, lot numbers, and
serial numbers. Lookup data from the database includes:
• Column description, temperature limits, form factor, and
nominal dimensions.
• Liner description and internal volume.
• Injector syringe description, type, and volume.
Barcode reader power
The USB version of the barcode reader gets its power from
the PC’s USB port.
The RS- 232 version of the barcode reader uses its own
power supply. Plug the power cord into the appropriate
outlet. When power cycling the GC, turn off the RS- 232
barcode reader too.
To avoid damaging the barcode reader, do not connect or disconnect
the RS-232 barcode reader to or from the GC when either GC power
or barcode reader power is on.
