    Note: Metallized coatings on some vehicle windshields and windows shield the RF energy emitted by the Encompass 4 Reader and may cause tags to be misread. Many metallized windshields have areas that are not metallized in which the tag can be placed and reasonable results achieved. If there are no openings in the metallized coating in which to install an interior tag, install exterior- type tags on the exterior of the vehicle.

    The Encompass 4 Reader Read Zone The Encompass 4 Reader must be able to read the tag data properly within a specified area, called the read zone, without reading other nearby tags or interfering with other Encompass 4 Readers at the site. The following are some of the factors that affect the size and shape of the read zone: •...

  • Page 28: Table 1 Examples Of Staggered Reader Frequencies

    Other sources of interference and reflection The Encompass 4 Reader must be positioned to allow the RF signal to travel to and return from the tags within the designated range and be placed in an area where it is not likely to be bumped out of alignment. If the antenna becomes misaligned or some nearby structure is added or removed, system operation can be seriously affected.

  • Page 89: Basic Protocol

    Encompass 4 Reader System Guide Basic Protocol With basic protocol, messages sent to and from the Encompass 4 Reader and the host are transmitted without error checking. For each host transmission, the Encompass 4 Reader returns a Done or Error message to the host.

  • Page 90: Data Inquiry Protocol

    The selection of data inquiry protocol affects data mode operation. As the Encompass 4 Reader acquires tags, it buffers them but does not transmit them. Instead, the host must poll the Encompass 4 Reader for each tag by sending an ASCII CRTL-E character (hexadecimal 05). The Encompass 4 Reader transmits one message (tag ID or report data) for each CTRL-E it receives until the buffer is empty.
