PSC Industrial Network

Key Advantages 

• Greater volume of data available to the Host due to speed of bar code data capture combined with high speed communications.

•  Better accuracy and reliability of data collection due to bar code technology combined with a highly reliable data exchange protocol of the network.

•  Maximum distance of RS485 communication line up to 1.2 km.

Components of a Typical Network

• 1 x Host Computer

• 1 x Netdriver decoder (Master B+)

• Satellite decoders (Master BB+ & Master B+)

• SM485 adaptor SMARTNET

• 1 x PCNET RS232 Cable

• COMNET Cables

• 2 x IMPNET (Terminators)

• 1 x PSU per decoder

• Bar Code Scanners

The netdriver manages up to 255 satellites and acts as a Multi-plexer, storing up to 4KB of data.

Drives the Satellite stations via high speed communications "Multi-drop polling".

Also manages bi-directional data traffic between the network and host.

The satellites are data capture workstations. (Standard MasterBB+ decoders).

Each has a specific address (e.g. 000, 001…..254).

Connected satellites can be turned off without disturbing the network.

This adaptor is a "T" box, connects the stations (Netdriver and Satellites) to the network line.

All network exchanges are controlled by the SM485 adaptor.

It manages the network protocol between the Netdriver and the Satellite.

The communication cable.

Stations are connected together via the COMNET cables.

This cable conforms to the RS485 standard.

The impedance adaptors are SUB-D 25 pin integrating a resistor.

These are terminators.

Two units are required for each network installation - one at each end
