The label on the cradle contains LED indicators and a scan finder button. When the button is pressed, the cradle transmits a “broadcast” message. All properly configured scanners (Radio RX Timeout set to keep the radio “awake”) linked to that base (through a bind or a join sequence) and within radio range coverage will emit a beep sequence once every 2 seconds for 30 seconds. A scanner is considered to be linked when the last transmission ends properly. The scan finder works only in stand-alone layout (point to point or multiple readers).

INTRODUCTION

1 INTRODUCTION

Datalogic renews its range of industrial laser scanners introducing the PowerScan family: PowerScan

D8330 and PowerScan® M8300. Robustness and ergonomics

remain unsurpassed: clearly audible beeper and bright "good read" LEDs for areas where noise levels are normally high; the aim mode, which helps point to the right code, has now been extended to the whole PowerScan completely suspended on shock absorbers and a careful choice of the body materials, such as the co-moulded rubber, protect the PowerScan

family. Optical parts are

from damage

due to "falls".

New enhanced architecture, based on an M16 high-speed microprocessor, enables exceptional performance for promptness and reading speed of standard codes as well as the ability to read poorly printed and damaged codes. Puzzle Solver Technology™, a patent from Datalogic, adds further strength to the PowerScan® powerful engine.

In all applications where mobility is a value, the new PowerScan® M8300 represents the key to increase productivity and flexibility in the working area. PowerScan® M8300 communicates through a low power, license free radio in the 433 MHz band (910 MHz for USA version) and allows bi-directional communication between the base station and the host. PowerScan® M8300 also includes a display and a 3 push-button keypad. Thanks to these features, the operator can receive information from the host, interact with the central system and visualize the code read. The cordless system offers scalable solutions to solve simple applications and complex projects:

• Point to point: each reader is associated with its own base station;

• Multipoint: up to 32 readers transmit data to one base station;

• Network: to cover a wide area, connecting up to 16 bases and 512 readers

simultaneously working in automatic roaming.

PowerScan® M8300 is 100% compatible with STAR-System™, the new Datalogic RF narrow band solution for mobile applications that provides the widest family of narrow band devices on the market.

Your PowerScan® reader is supplied with its own Quick Reference Guide, which provides connection, diagrams, reading diagrams, basic application parameter settings, default values, and specific technical features. You can use either the Quick Reference Guide or this Manual for initial configuration in order to set the default values and select the interface for your application. This manual provides all the necessary information for complete mechanical installation and system software configuration.

2.8 NETWORK CONNECTIONS

2.8.1 BC-8060 Network Connectors

The multidrop network is a bus system which is propagated from one BC-8060 cradle to another using individual cables. This is possible thanks to the RS-485 connector on the front panel of the cradle.

Power Supply

All cradles are connected together within the bus system through the Datalogic RS-485 splitter cable (CAB-428, part number 90A051950), which must be inserted in the RS-485 cradle connector.

Obviously cable length is to be kept to a minimum as with all bus systems.

INSTALLATION

2.8.2 Network Cabling

The Multidrop line is made using RJ45 connectors and a cable having the following specifications:

• twisted pair AWG 24 wires

• 120 Ω impedance

• maximum network cable length 1200 meters

When wiring the multidrop cables, note the following:

Pin 8 (or 7) can be connected only if the power has to be propagated from a cradle to a STARGATE™ base station or STAR-Box™ converter via the cable.

Pins 5 (or 4) should always be connected as reference ground.

To avoid excessive voltage drop, it is recommended not to propagate power between BC-8060 cradles when used as battery chargers but to supply each cradle individually. The total number of devices, which can be connected to a single power supply, depends on the power supply voltage, the wire length and resistance and therefore the voltage drop. Do NOT connect VDC+ between network devices that are individually powered.

Data and Power Supply

2.8.3 Network Termination

The first and last cradles of the chain (the two ends of the bus) must be properly terminated. The cradle has an internal terminator that can be selected via jumper. For this selection you must open the device.

No Termination Static Dynamic

Terminator for Multidrop Network

Static termination works for all network configurations. However, the network is always under load even when no data transmission takes place.

Dynamic termination can be used for baud rates at or above 38400 and provides less load on the network when idle.

INSTALLATION

2.9 POWERSCAN® M8300 BATTERY MAINTENANCE

2.9.1 Battery Charging

Once the system is connected and powered, you can place the PowerScan into the cradle to charge the battery. When the reader is correctly inserted in the cradle, the "Reader" red LED on the cradle goes on to indicate that the battery is charging. The "Reader" green LED on the cradle goes on when the battery is completely charged.

System cables to Host

In this layout the BC-80X0 cradle is connected by a dedicated cable using the RS-232 interface to a C-BOX connection box as part of a fixed scanner network. This allows the flexibility of a hand-held reading station integrated into a variety of fixed scanning applications so that all readers (both fixed and hand-held), in the system provide communications to the Host.

The various C-BOX models provide many interface types for the Host system such as RS-232, RS-485, Profibus.

POWERSCAN® M8300 SYSTEM AND NETWORK LAYOUTS

3.2 MULTIDROP STAR-SYSTEM™ NETWORK LAYOUTS

Even though many stand-alone systems can operate in the same physical area without interfering with each other, it may be desirable to bridge data from multiple base stations in a network to a single

Host. PowerScan® M8300 readers are compatible with STAR-System™ networks. These networks provide seamless active roaming for any RF reading device in the system.
