Required Materials
You need the following materials to mark the read zone:
• Test tags, supplied by the TransCore dealer or distributor
• Piece of windshield-type glass 0.190 to 0.230 inches (4.82 to 5.84 mm) in thickness and
approximately 12 inches (30.48 cm) square for testing with a sticker tag
• Audible circuit tester and 9V DC battery for circuit tester power as described in the section “Bench
Testing the Encompass 4 Reader Before Installation” on page 4-39.
• Piece of chalk or roll of tape
• Plastic or wooden yardstick for ATA or IAG tags
• Vinyl electrical tape or hook-and-loop material
Caution
Both the eGo Plus Sticker Tag and eGo WST have a reduced read range when not attached to
glass.
Procedures
Note: Using test tags that are not mounted to vehicles give a general idea of the read pattern but
the pattern will vary somewhat when actual vehicles with tags are tested. Final adjustments must
be made with tags properly mounted on a variety of vehicles.
To mark the read zone
1. Confirm the following:
• You have correctly connected the power supply as described in “Connecting the AC Power
Supply” on page 4-36 and “Connecting the DC Power Supply” on page 4-37.
• You have correctly connected communications as described in “Connecting Communications” on
page 4-55.
• You have correctly connected sense input and sense output circuits as described in “Sense Input
Circuits” on page 4-59 and “Sense Output Circuits” on page 4-61.
• You have correctly connected the red and white leads from the audible tester to the red and white
pair of wires from the Encompass 4 Reader power/communications cable.
2. Start the terminal emulation application.
3. Choose the com port to which the communications interface is attached and set the properties as:
• Bits per second: 9600 baud

• Parity: none
• Stop bits: 1
• Flow control: none
4. Cycle the power on the Encompass 4 Reader and ensure that the sign-on message displays.
