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. The
Portable RSE does not write to the OBU.
Data Storage
The data read by the Portable RSE is stored internally in the Portable RSE where it can be either be viewed or
downloaded to the LC. The Portable RSE can store data from a maximum of 1000 OBU reads. Once 1000 OBUs have
been read, the data must be downloaded to an LC or erased before more OBUs can be read. OBU data is automatically
erased from the Portable RSE once it has been downloaded to the LC. See Erasing OBU data on page 38 for more
information.
Synchronization
When performing a read, the Portable RSE checks for incoming RF signals from toll plaza Readers. If trigger pulses
from toll plaza Readers are detected, the Portable RSE determines the length of time between trigger pulses (i.e. the
length of the superframe) and sends its own trigger pulse when it is unlikely to conflict with the toll plaza Reader. This
ensures data is not corrupted in either the Portable RSE or toll plaza Readers.
Note: To avoid potential performance impacts on toll plaza Readers, the Portable
RSE must be positioned in accordance with the requirements of this section.
