2.45 GHz ISM band and allows identification of tags at a distance up to 10 meters, even at high speeding passage. The NEDAP TRANSIT system features radio frequency identification equipment using modulated backscatter. In this method, the tags send there code to the reader by modulating and reflecting the signal transmitted by the reader.
The U-Link setting: “ Inductive Mod select, K-13”, on the Power supply unit allows for the selection between voltage- or current coupled receivers. Contact NEDAP when in doubt which kind of external inductive receiver you want to connect to the TRANSIT system.
3 – Communication interfaces. Universal thin server. ( Art. No.: 7806434 ) The Universal Thin Server (UTS) is designed to connect NEDAP RF-ID devices with a serial interface to an Ethernet network using the TCP/IP protocol. The Ethernet network interface speed is 10-Mbit.
One has to keep in mind that the misalignment is most of the time present in two planes. This makes simple evaluation of the coverage area difficult. A computer model has been developed in which most geometries can be evaluated. Contact Nedap when in doubt. In par. 4.5 the detection area for a number of practical situations is given.

The window-tags can be mounted easily behind the windshield of a vehicle. The booster-unit is a special window tag, which is able to hold a NEDAP inductive identification card. This card is read by the booster. The combi-booster combines the features of the window-tag with a booster allowing to identify both vehicle and driver.
P61 firmware 4 APPLICATION INFORMATION The main function of the reader is to detect NEDAP transponders and to transmit its identification number to a host computer. The id-number will be sent to the host in a so-called event message. A detailed description of each event message is given in chapter 4.1.1.
Receive Figure 7: Timing diagram DC2/DC4 protocol When an event message (initiated by Nedap) is not acknowledged the event is NOT be cleared from the event buffer. Nedap resends the event message later. When a reply message is not acknowledged the reply is lost. The host has to resent the request in order to get the reply again.
