8. Pass the correct test tag for your reader application in front of the Encompass 4 Reader or antenna.
The audible circuit tester should sound a tone when the tag is read. If no tone sounds, ensure that
steps 1 through 5 were performed correctly and that you are using a compatible tag. Repeat steps 6
and 7. If no tone sounds, contact TransCore Technical Support.
9. Disconnect the circuit tester from the Encompass 4 Reader power/communications cable.
10. Disconnect the power and communications connections made for pre-installation testing.
Note: You will need the audible circuit tester again to determine the read zone when installing the
Encompass 4 Reader at the site.
Mounting the Encompass 4 Reader
This section lists procedures and materials required for mounting the Encompass 4 Reader on a round
pole or on a ceiling, wall, or other flat surface based on the site’s requirements.
In permanent installations using an antenna, the Encompass 4 Reader should be positioned as close
as possible to the antenna. Long cable runs increase system sensitivity to noise. Refer to “Table 4
Recommended Cable Length from Transformer to the Encompass 4 Reader” on page 2–17 for maximum
RF cable lengths.
The Encompass 4 reader has a weep hole located on the bottom left side to allow moisture to escape.
The reader should always be positioned so that the side with the weep hole is lower than the top. For
overhead mounting, the reader angle should be at least 10° ( Figure 29 ).
