MOXA NE-4000T Embedded Network Enabler brings access entry systems into the network era.

 

Fortuna Impex Pte Ltd. specializes in microprocessor-based systems for industrial applications, and recently extended its expertise in the access control systems arena by designing and manufacturing several state of the art products.

 

Attendance Recording Systems, which often use bar code technology, are one of the main products that Fortuna Impex produces. Bar code technology has a competitive edge due to non-contact sensing, long MTBF, durability, and ease of manufacturing. Furthermore, bar code reading technology can be used to prevent unauthorized access to restricted areas.

 

Fortuna Impex's new Gateway 2000 Tip is a Time and Attendance System that combines a proximity bar code reader, touch pad for inputting a PIN, and fingerprint reader, to give businesses a fool proof method for preventing unauthorized personnel from entering restricted areas. The product uses an RS-232 interface to send bar code, PIN, and fingerprint data to a computer host. However, the fact that an RS-232 connection can only guarantee accurate data transmission over a maximum distance of 15 meters places a big restriction on where the computer host can be located.

 

Another problem arises if a large number of card readers are combined to form a more complex entry system. One option is to design a system that uses several PCs, with one PC located near each device. However, the cost of purchasing so many PCs can be prohibitive. Another option is to use RS-232 to RS-485 converters to extend the transmission distance, but the wiring cost of this option could be high,  and customers often complain about the low pulling speed when RS-232 signals are transmformed into RS-485 signals.

 

To get around these problems, Fortuna Impex used Moxa's NE-4000T Embedded Network Enabler to create a low-cost RS-232 to Ethernet solution. Since Ethernet signals can be transmitted over a long distance, and Ethernet connecters can be installed just about anywhere, Fortuna Impex's customers are able to combine tens, or even hundreds of Time and Attendance System devices into one large system. Serial signals generated by bar code, PIN, and fingerprint readings are easily transmitted to one centrally located computer, which can be used to control the entire system.

 

整體效益

  • Transmit RS-232 signals to any network host
  • One centrally located PC can control several RS-232 devices
