Installation at the Site
After pre-installation testing, using the site plan and frequency plan previously
developed, you are ready to install the reader on site.
1. Confirm the following:
•
All construction is complete and electrical and communications
cables of the appropriate length are in place.
•
A watertight junction box with terminal strip is present.
•
A dedicated power supply of the appropriate voltage is present.
•
The placement of the readers follows the site plan.
•
The readers are the correct distance apart, side fire or overhead.
Normally 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 normally are used within parking garages and other
areas where a mounting surface already exists.
Side-fire installations normally are used where the lanes are out in the open
and the installation of a pole is sufficient to mount a reader.
For side-fire reader placement, optimum tag placement is on the side of the
windshield nearest the reader; for overhead reader placement, the optimum
tag placement is in the upper center of the windshield.
2. Mount the reader on a 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.
For reliable reader operation, ensure that the reader is connected to
Earth Ground. Do this by connecting the cable shield of the
communications cable to Earth Ground. TransCore strongly
recommends that you follow the National Electric Code for lightning
protection for the locale where you are installing the Encompass 4
Reader.
3. Connect all wiring as described in Pre-Installation
Testing Step 1 on page 5 using the appropriate RS– 232
or RS– 422 Wiring Diagram on pages 10 and 11 as a
guide.
Also connect sense input and sense output circuits using the Sense
Input/Output Cabling Assignments table on page 12 as a guide.
4. Start the terminal emulation application Microsoft
HyperTerminal by selecting Programs>Accessories>
Communications>HyperTerminal and press ENTER as
described in Pre-Installation Testing Step 2 on page 6.
