Bar code reader installation and operation

1. Installation
The bar code reader is the optional spare parts for DR-7000 series semi-automatic chemistry
analyzer, there is a serial port on analyzer back board for it installation. The operation is very easy,
operator only need to insert the bar code reader connector plug into the proper serial port.

Notice: The equipment should be powered off before bar code reader installation.

2. Operation
(1) The bar code reader could read Code-39, Code-128, EAN-8, UPC-E and Inter leaved 2 of 5 bar
code automatically and the total digit for the bar code number should not more than 10 letters,
otherwise, it will not workable.
(2) The operator could do the scan operation before each test (ID should be setup ON) and then the
bar code number will be saved into ID number. There is only one bar code number for each
sample, therefore, it is only need to scan one time for the same sample or the equipment will save
the last scan one as the final one.
(3)The bar code reader belongs to far-distance Reader, the operator only need to aim the scan point
at the barcode number and then press the trigger, so that, the real-time bar code info will be
shown on the screen.
(4)The bar code reader reads the barcode by the light line center on the top of it, to avoid mistakes,
the light line should cover the whole barcode and keep proper bevel with the trigger before
reading.

Connection of stylus printer

Instrument could connect EPSON LQ300K+ stylus printer. (Other type stylus printer can be used as
well, but it may cause some change in print speed and character position.)
