5. Click Test Axis.
6.8.7 Test axis
This form shows how well each axis / antenna pair is working. The test sends 10 tag commands and
expects all commands to be received on each receiver stream.
Readers such as the Mars-24 and Mars-8 have eight receiver streams; the axis test expects to receive
replies on all eight streams. The form shown in Figure 30 shows the results of a successful antenna test
for an eight stream reader.
Readers such as the Mars-1, Mars-2, Mars-4, Mars-6 and MDR-1109 have two receiver steams, for these
types of readers’ only receiver streams G and H should show replies. Channel G should show 10 replies
and channel H should show more than 7 replies the other channels can be ignored. The form shown in
Figure 31 shows the results of a successful test for a two steam reader.
The form elements are described in Table 17.
• This test must be done using a single tag placed on the antenna under test.
• The tag must be configured as a Normal powered tag.
• For all antenna types except the panel antenna we recommend using a 25mm round tag or
one of equivalent size. For panel antennas we recommend using a credit card sized antenna.
If your reader does not pass this test it will not read and write to tags reliably. Check there are no
metal other sources of interference near the antenna.
It is important that the test is stopped before this window is closed as this test configures the reader
to operate in a different mode to what it would be set to when just reading and writing to tags. If the
form is closed by accident disconnect ReaderManager from the reader and power cycle the reader.
