Kapsch TrafficCom Portable RSE 2. OVERVIEW Introduction The Portable RSE is a hand-held device that can read all IAG-compatible On Board Units (OBUs). The OBU data is stored in the Portable RSE where it can be viewed and later downloaded to a Lane Controller (LC). The Portable RSE supplements existing Electronic Toll Collection (ETC) systems and can be used for applications such as valet parking, transponder screening, and enforcement.
Kapsch TrafficCom Portable RSE Antennas The Portable RSE is equipped with a standard locally attached antenna that allows the unit to read Transponders. It provides a connection for the same type of antenna to be remotely attached via a RF cable for increased distance from the PDA to the tag. A dedicated terminal is located on the top of the Portable RSE for each type of antenna. The unused antenna terminal must be terminated with a 50 Ω terminating resistor.
Kapsch TrafficCom Portable RSE Stylus CAUTION: Do not use sharp objects on the Portable RSE touch screen. Tapping the touch screen with sharp objects can damage the touch screen. The stylus in Figure 2-3 is stored in the Stylus holder on the back of the device. For best results, it is recommended that you use the stylus to tap the screen when using the Portable RSE.

Kapsch TrafficCom Portable RSE How the Portable RSE works When an OBU read is initiated, the Portable RSE scans for any IAG-protocol OBUs within range. OBUs within range respond by transmitting their data to the Portable RSE. This data is then decoded and displayed on the LCD. The Portable RSE includes a standard whip antenna that allows the unit to read OBUs at a distance of approximately 5 feet. An optional remote antenna is available that can extend the reach of the device to approximately 9 feet.
