With the internal laser scanner
A
bar code
is a series of vertical bars
and spaces used on nearly every
item in business today.
A second method of entering data is with the PTC’s
internal laser scanner. When you scan a bar code the
PTC is programmed to read, the PTC and scanner
interpret the data and store it in the PTC’s memory.
Storing data
Data entered into the PTC can be stored in files in the
PTC’s memory.
Each file holds a separate group of application-related
data. For example, a PTC used to collect many types
of data (sales orders, inventory changes, and
employee hours) would store all data relating to sales
orders in one file, all data relating to inventory
changes in another, and all data relating to employee
hours in still another.
Communicating data
After collecting the data, the PTC must either
transmit it to a host computer for processing or send
it to a printer, or both, to make it useful to you and
your organization. The PTC-960L can transmit data
via an optional communication cradle or by being
connected by cable to a host computer, printer, or
other accessory.
Once the host computer receives the data from the
PTC, it uses that data to update its master files and
records. In some cases, the host computer may even
transmit data back to the PTC, asking you, as the
PTC’s operator, to perform a new task.
