Bar Code Reader
(Optional)
1
Located to the left of the cartridge array, the L200 bar code reader (see
figure 6) performs cartridge inventories in less than three minutes.
The bar code assembly contains a scan head that communicates with
the library controller card on an RS-422 communications link. During a
cartridge inventory, the scan head illuminates and reads the bar code
labels on the cartridges and transmits the results over the serial
communications link to the library controller card.
