Page 40: Reader And Tag Alignment
Reader and Tag Alignment The position of the Encompass 4 Reader and placement of the tag on the vehicle must be compatible. Also, consider any existing tagged vehicles now using the facility to determine the optimal Encompass 4 Reader location and orientation at the site.
Page 41: Polarization
Developing the Site Plan Polarization The polarization of the tag must be aligned in the same direction as the Encompass 4 Reader, as shown in Figure 2-1. Note: Matching the tag and antenna polarization is critical to obtain optimal system performance.
Page 42: Unobstructed Line Of Sight
Encompass 4 Reader, the tag is directly facing the reader and the line of sight is clear between the Encompass 4 Reader and the tag. If a fence or barrier is between the tag and the reader, the Encompass 4 Reader cannot reli- ably read the tags.

Existing signal interference at the site 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.
Page 49: Other Encompass 4 Readers In The Area
• 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.
Page 50: Gate With Center Island Configuration
Gate with Center Island Configuration Figure 2-6 illustrates a typical gate application with the Encompass 4 Reader units positioned on a center island to read tags mounted on the inside windshield on the driver’s side (United States). The readers are placed to allow time for the gate to open so the vehicle can roll through without stopping while not allowing room for an untagged vehicle to be between the vehicle being read and the gate.
Page 51: Parking Garage With Ticket Island Configuration
Figure 2-7 Parking Garage Application Overhead Reader Installation Configuration Another option for Encompass 4 Reader placement is to mount it overhead in each lane as illustrated in Figure 2-8. This illustration assumes that tags are mounted on the inside center windshield or center bumper of the vehicle.
Page 52: Lane Configurations For Encompass 4 Readers Using An External Antenna
Any of these factors can alter or degrade system performance. When designing your site plan, you must consider permanent structures and transient factors in the vicinity that may affect RF signals being generated by the Encompass 4 Reader. Permanent structures include buildings, chain link fences, guard shacks, and gates.

All Encompass 4 Reader commands are preceded by the start-of-message character (#). The end-of-message sequence expected from the host is a carriage return (CR). The Encompass 4 Reader terminates messages with a return and a line-feed (CR/LF). For example, the command #01 Switch To Command Mode is typed as follows: #01<ENTER>...
Page 132: Command Response Conventions
Command Response Conventions Like the Encompass 4 Reader commands, responses are preceded by the # character.

Page 135: Tag/Message Buffer
General Software Information Tag/Message Buffer In basic communication protocol, the Encompass 4 Reader does not provide tag mem- ory storage beyond the quantity required for uniqueness checking. This feature allows adequate buffering of tag data under normal operating conditions. The Encompass 4 Reader cannot operate as a stand-alone component.

Page 140: Basic Protocol
Parity is required to achieve the most reliable communications. If parity is enabled, both the Encompass 4 Reader and the host must issue a message if any received char- acter has a parity error. However, the message must not be transmitted before receipt of the eom character.
Page 141: Data Inquiry Protocol
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 a CTRL-E character (hex 5 digit). The Encompass 4 Reader transmits one message (tag ID or report data) for each CTRL-E it receives until the buffer is empty.
Page 142: Ecp Host Ack/Nak Response
If the host receives a <som> character in the middle of a data message, the message in progress is aborted. The assumption is that an <eom> was lost and the Encompass 4 Reader is in the process of retransmitting the previous message.

Page 148: Timing And Synchronization
The ECP is largely independent of baud rate. The timeout delays previously described are a function of baud rate. The Encompass 4 Reader supports an ECP timeout, which applies equally to both transmit and receive. The receiver’s minimum timeout delay equals the time to transmit/receive the longest anticipated message at the current baud rate setting.
Page 149: Reader-Addressed Failure Conditions
The host computer switches its communications parameters immediately after the transaction is complete. As noted, the message initiator, such as the Encompass 4 Reader in data mode and the host computer in command mode, starts a timeout counter at the time a message is transmitted.

Page 151: Transmission Timeout
Asynchronous Message/Command Message Collision If the Encompass 4 Reader transmits asynchronous data at the same time that the host sends a command, the Encompass 4 Reader gives priority to receiving the command. It processes the command and sends a message before it retransmits the asynchronous data.
