2.5 TYPICAL LAYOUTS

The DX8200A scanners can be connected in a variety of layouts depending on the number
of scanners used and the required complexity of the reading station. These layouts range
from Single Stand Alone to Complex Lonworks Networks.
Vac models can be used for point-to-point connections eliminating the need for an external
PWR power supply. They can also be used in Lonworks layouts as long as no power cables
are used, (sufficient power is not available to be propagated to other scanners in the
network).
For Vdc models several power supplies are available to power the reading stations.
Photoelectric sensors used as code presence sensors and optical encoders to signal
conveyor speed are also available accessories.
The following typical layouts refer to the system hardware configurations, but they also
require the correct setup of the software configuration parameters (see par. 3.2 for details).
The accessories and cables indicated in the following figures are Datalogic products. We
suggest their use to guarantee the correct system functioning.

2.5.1 Point-to-Point

Using a Point-to-Point layout, the data is transmitted on the Main interface as well as on the
Auxiliary interface. The Main interface can be selected for RS232 or RS485 full-duplex
communications. Two different layouts are available according to the DX8200A reader model
used for the connection.
Standard Models
When On-Line operating mode is used, the reader is activated by an External Trigger
(photoelectric sensor) when the object enters its reading zone. In the following case, the
signal is passed to the DX8200A by the C-BOX 100, which also supplies the system.
