Site Licensing
Encompass® 4 Readers radiate more than 3 milliwatts of RF power, and must be licensed under Federal
Communications Commission (FCC) Section 90.239. An FCC license provides the user with the legal
authorization to operate the Encompass 4 Reader on the licensed frequencies at the site specified in the
license. The FCC license also provides the user with protection and authorization to maintain the system
should any other RFID product be used in the licensed area after the Encompass 4 Reader equipment is
installed.
The site owner must complete and file Form 601, FCC Application for Wireless Telecommunications
Bureau Radio Service Authorization. Forms are available online at the FCC Internet site https://www.fcc.
gov/licensing-databases/forms.
The authorized frequency band for this product in the United States is 911.75 to 919.75 MHz. Only an
authorized installer or service technician should set the RF frequency of the Encompass 4 Reader to the
frequency specified in the FCC site license.
Designing the Site Plan
Design the site plan before ordering equipment and installing the Encompass 4 Reader. If the site
configuration diers significantly from the recommendations in this guide, contact TransCore Sales
Support.
Determine the Reader and Tag Combination
The Encompass 4 Reader is capable of reading the following protocols and formats:
• TransCore Super eGo® (SeGo)
• eGo (ISO 18000-6B)
• ATA/AAR/ISO 10374
• IAG (Interagency Group)
• Wiegand
Table 1 lists the Encompass 4 Reader models and features.

Quick Start Guide
TransCore Proprietary6
Reader Placement
Encompass 4 Readers may be mounted on a pole at the side of the lane (side-fire), or on a gantry or
surface extending over the center of the lane (overhead). The reader should be located in a place
where it is not likely to be bumped out of alignment. Readers should not directly face each other or be
positioned back-to-back.
For a pole mount installation, readers should be installed as high as possible so that the reader can be
pointed down to control the read zone and minimize interference in the adjacent lane.
Tag Placement on Vehicle
Most TransCore RFID tags should be mounted in the center of the windshield to the right of the rear-
view mirror post. Refer to the installation instructions for your specific tag for more information on tag
placement.
Site Layout, Lane Type, and Trac Flow
Become familiar with the configuration of the site and its proximity to other sites. Determine what the lane
types will be, and identify any equipment that will be used, such as ticket machines or proximity readers.
The number of readers that will be required depends on the number of lanes at the site, how they are
grouped, and total entry and exit points. Measure lane widths and the distance between adjacent lanes,
taking into account any island/barrier width. TransCore recommends a lane width of 12 feet or less, with
the distance between the readers at least 12 feet or more.
Interfaces to External Equipment
For eective lane layout and transaction framing, the maximum distance from the entry loop to the reader
should be about 8 feet. The distance from the reader to the gate arm should be 3 to 4 feet before the
gate. If the read zone is much larger than 3 to 4 feet, a following car may be read (skip read), allowing a
non-tagged vehicle to enter the facility.
The readers are typically configured to be loop-activated (on by presence). Readers may be alternatively
set to have RF on continuously. The choice depends on trac volume and possible interaction with the
other in-lane components.
Electrical and Communications Requirements
The Encompass 4 Reader requires 16-20VAC, 47-63HZ, or 16-28VDC for proper operation. Contact
TransCore Sales Support for a list of recommended transformers and cable lengths.
The reader is available in RS–232 or RS–422 models. Maximum distance for RS–232 (3-wire serial) is 50
feet at 9600 baud. Maximum distance for RS–422 (4-wire dierential signal) is 4000 feet at 9600 baud.
The baud rate can be adjusted to accommodate noisy environments.

TransCore Proprietary 7
Pre-Installation Testing
Bench Test the Reader
Bench test the reader using the following equipment:
• Audible circuit tester (buzzer) or volt meter with continuity tester
• Compatible power/communications cable
• PC using a terminal emulation program such as Tera Term or Microsoft HyperTerminal
The Encompass 4 Reader uses a single 26-pin (13 twisted pair) cable to interface with power, I/O, and
communications signals. The reader cable can be directly connected to external devices or routed to
other components via an external junction box.
Connect Hardware
1. For AC powered units, connect the power wires from the cable to the transformer using the color
coding as described in Table 2. Do not apply power to the transformer at this time.
For DC powered units, connect leads to an appropriate power supply. Do not turn on the power
supply at this time.
Table 2 Power Connections
Colored Wire Pair Use These Colors Connect to Transformer
Terminal Strip
Brown/Red Orange and Brown L1 (16 to 20V AC)
Orange/Red Red and Red L2 (16 to 20V AC)
2. For Encompass 4 Readers with an antenna port, connect the antenna prior to powering up the reader,
using an N-type connector.
3. Connect the leads from the audible tester to the red and white pair of wires from the
power/communications cable.
4. For RS–232 units, refer to Table 3 for wiring instructions. For RS–422 units, refer to Table 4.

Frequency Plan
The Encompass 4 Reader FCC-approved frequency band is 911.75 to 919.75 MHz. This relatively narrow
frequency band requires careful planning to maintain the desired 2 MHz frequency separation between
adjacent readers.
If readers are spread out within a facility (readers ½ mile or so apart) and loops are used, then frequencies
may be reused. Figure 2 shows frequency separation for 4 lanes.
Table 5 shows an example of the frequency settings for up to 14 lanes, along with the two dierent
commands that can be used to set the reader operating frequency. Command #642NN is backward
compatible to older readers including the Encompass 2 reader, and provides a 0.5MHz resolution.
Command #647XXX provides a 0.25MHz resolution for setting the reader frequency. Either command may
be used to set the reader frequency. Note that the response to Command #527 (Display RF Parameters)
will include either two or three hexadecimal characters, depending on which command was last used to set
the reader frequency.

Installation at the Site
Complete pre-installation testing before installing the reader on site.
Before Starting Installation
Confirm the following:
• All construction is complete and electrical and communications cables are of the appropriate
length and in place.
• A watertight junction box with terminal strip is present.
• A dedicated power supply of the appropriate voltage is present.
• Placement of the readers follows the site plan.
• The readers are in the correct positions: side-fire or overhead.
Typically, readers (or antennas) are installed either on the side of the lane, pointing into the lane (side-fire)
or directly over the lane, pointed downward (center-fire or overhead).
Overhead installations are typically used in parking garages and other areas where an overhead mounting
surface already exists. These antennas are normally set to 10° down-tilt.
Side-fire installations are commonly used when the lanes are out in the open and the installation of a pole
is sucient to mount a reader.
Mount Reader on Round Pole or Flat Surface
Proper reader angle may require both up-down and right-left adjustment. Ensure that the correct
wall-mount or pole-mount bracket is used in the reader installation.
CAUTION:
For reliable reader operation, ensure that the reader is connected to Earth Ground.
Connect the cable shield of the communications cable to Earth Ground. TransCore strongly
recommends following the National Electric Code for lightning protection for the locale

Reader Set Up
1. Use reader commands to query status and set up the reader.
2. Make sure that each reader is set up to the appropriate settings.
3. Adjust reader angle and power to optimize read zone for each reader.
4. Check for interference from each reader or the environment, using a portable field spectrum analyzer
if one is available.
Note: If using Wiegand tags, configure the reader for Wiegand operation and connect the
Wiegand interface. Refer to “Configure for Wiegand Operation” on page 11.
5. Disconnect the computer and connect the reader to back end devices. Recheck read zone and for
interference between readers.
6. System-test the reader to verify that the gate opens when a valid tag is read.
7. Once all in lane testing is complete, perform a system test using tagged vehicles passing through
numerous lanes. The tag reads are sent to the gate controller back end system for validation.

Troubleshooting
Communications problems between the reader and back-end host
These problems may be caused by incorrectly wiring the communications cable, using the wrong cable,
having a too-long cable run, or incorrectly setting communications parameters between host and reader.
Cable run for RS–232 exceeds 50 feet in length
Fifty feet exceeds the maximum length for RS–232 interface. The interface should be converted to
RS–422, wireless modem, fiber optic, or Wiegand.
Long RF cable runs to antennas
For the external antenna-series Encompass 4 Readers, long RF cable runs between the reader and
the antenna may cause signal degradation or loss. This scenario may be site-specific, but TransCore
recommends limiting antenna cable runs to less than 3dB of cable loss.
