Page 41 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 42: Other Encompass 4 Readers In The Area
Encompass 4 Reader System Guide 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 43: 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 44: 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 45: 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.
Page 46: Existing Interference
RF signal. Interference may degrade both reader and tag performance. Existing interference at the site may be shielded, removed, or positioned further from the Encompass 4 Reader and/or antenna. In some cases, changing the operating frequency of the Encompass 4 Reader may provide a simple solution.
Page 47: Electrical Power
A dedicated electrical power supply must be present at the site and available to the Encompass 4 Reader at all times. The power must be 16-20V AC or 16-28V DC. A step-down transformer is available (North America only) to convert a 120V AC duplex wall outlet with ground to 18V AC, as is a step-up transformer to convert a low-voltage 12V AC outlet to 18V AC.

The Encompass 4 Reader has two sense input circuits and three sense output circuits available. The sense input circuits can be used to notify the Encompass 4 Reader of external events and are designed to be connected to a free-of-voltage dry contact.
Page 103: Sense Input Circuits
Figure 4-16, sense input0 is through the red/green wire pair on the I/O pigtail. The Encompass 4 Reader expects the sense input0 circuit to close when a vehicle is present (i.e., a normally open condition). The minimum presence true period is fixed at 0 ms, which indicates that no delay occurs in closing the circuit when a vehicle is present.
Page 104: Table 4-9 Sense Input/Output Cabling Assignments

Page 121: Switch To Command Mode Request
When the Encompass 4 Reader receives an ACK message, the system software treats the message as having been properly received by the host. The software increments the sequence number, and advances pointers to the next message in the Encompass 4 Reader’s message queue to prepare for sending the next message.
Page 122: Reader Command Response
Upon receiving a host command, the Encompass 4 Reader echoes the command’s sequence number in its response. Therefore, the host computer updates its sequence number upon receipt of a valid reader message.
Page 123: Sample Messages

Page 125: 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 126: 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 127: 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.

Page 135 Data Mode The Encompass 4 Reader is in the data mode upon power-up. While in the data mode, the Encompass 4 Reader sends all communications as data messages, such as tag IDs and reports, to the host computer. Reports provide information on input status changes (input0 and input1), a presence without tag report, and buffer overflow information.
Page 136: Command Mode
Note: The Encompass 4 Reader transmits ID codes to the host computer when the Encompass 4 Reader is in data mode. If the Encompass 4 Reader remains in the com- mand mode with tags passing through the read zone, all tag IDs are not reported.
Page 137: Command List
Commands Command List Reader commands are divided into groups based on primary function. The following sections provide information about each command in command number order. Refer to Appendix for listings of commands in numerical and alphabetical order. In the following text, the symbols < and > represent variable message data. These symbols are not part of the message syntax.
Page 138: Communications Port Control — Command Group 1
IDs or reports in buffer Communications Port Control — Command Group 1 Group 1 commands configure the parameters used by the Encompass 4 Reader to communicate with a host computer or terminal. These commands set baud rate, stop bits, parity, and end-of-line delay.
Page 139: N Select Parity
Done Command Group 2 Group 2 commands control the real-time clock which maintains the Encompass 4 internal time and date. This time and date can be appended to IDs, error messages, and sensor input reports. An internal battery supports the clock, so time and date are preserved if main power is lost.

Commands Append Information — Command Group 3 Group 3 commands append useful information to reader transmissions, such as IDs, error messages, and sensor input reports. Auxiliary information such as reader num- ber, antenna number (or manual entry code), number of times the previous tag was read, and sensor input status can be appended to the ID using the Group 3 commands.
Page 142: Id Filtering — Command Group 4
Group 4 commands set criteria for filtering (buffering or discarding) ID codes. These commands are useful for eliminating duplicate ID codes and selecting the type of tags read by the Encompass 4 Reader. 40 Transmit All ID Codes Command #40 instructs the reader to transmit all IDs without regard for uniqueness.
Page 143: N Select Unique Id Code Criteria (Anti-Passback Feature)
Commands 410N Select Unique ID Code Criteria (Anti-passback Feature) Command #410N instructs the reader to buffer and transmit ID codes according to the following test: an ID is read if previously decoded IDs have changed value at least N+1 times since the new ID was last received. IDs that do not pass the test are not read.
