LF Transmitter Output
Configuration and Operation 5-7
The Reader will respond with the parameter value, for example,
HE1=6
where 6 is the value for the HE1 parameter.
3. Set the Continuous DC Mode type of execution, by typing:
RCS=N <Enter>
RES=N <Enter>
REM=C <Enter>
RET=D <Enter>
Note If a parameter already has the wanted value (determined in Step 2), you do not have
to reset it.
4. Turn on the excitation field, by typing:
B<Enter>
Check the TAP voltage [V
TAP
] at the terminal block TB2 on the EXT95SC board
(see Figure 5-3) using an oscilloscope. The signal must be a continuous
unmodulated carrier of 128.25 kHz with a peak-to-peak amplitude of
V
TAP
=100±20V

.
Note When more than one Exciter 95 is used to create a wider excitation zone, a magnetic
coupling can appear. The phenomenon is explained in Chapter 4, Setup Guidelines in
the 95 Series RFID System Technical Guide. The coupling generates an unwanted
amplitude modulation with a frequency of several Hertz, the modulation depth
depending directly on the coupling. The installer has to monitor the TAP signal and
adjust the position of the E95 frames to obtain a minimum unwanted modulation
depth. The installer can increase the distance between frames, level the frames in the
same plane, or place the frames with the shorter sides (1m) in parallel. The minimum
amplitude of V
TAP
due to unwanted modulation must be larger than 60V

5. Turn off the excitation field, by typing:
C<Enter>
The TAP voltageamplitudeshouldbezero.
6. Turn on the LF field again, by typing:
B<Enter>
The TAP voltage signal should have the same value as measured in Step 4.
7. Set the wanted excitation mode.
To set a specific excitation mode, refer to Appendix C, Excitation Modes.Ifyou
want to return to the initial excitation mode as determined in Step 2, you have to
restore the values of the parameters modified in Step 3.
