Alignment Procedures
NOTE
Perform step
2
only when
a
Central Controller is not
available (i.e., lab or depot). Once the station is
installed back into
the system, perform the entire
procedure again for optimum performance.
2.
Inject
a 150
Hz
tone at 0.9
Vrms (closed circuit level) with
600
Q termination
across pins
4
(-) and
12
(+) of the
trunking
connector J2901 on the
TTRC
board. Proceed to step
5.
This
simulates
a
trunking
data
(TDATA)
signal
to
perform this alignment
procedure. Refer to
Figure
4-18 for the
location of
the
trunking
connector
J2901.
The
Fail Soft
LED
should not
be
illuminated.
3.
Connect
an
operational Trunked Radio Central Controller
to the station.
This allows
the
station that is being aligned to receive trunked data
(TDATA)
from the Trunked Radio Central Controller.
The
Fail
Soft
LED
should not be
illuminated.
4.
Verify
the station being aligned is disabled from the
Trunked Radio Central
Controller.
This
is accomplished
by pressing
the
Transmit Interface Board
(TIB)
disable
switch
on the
Trunked Radio Central Controller for
the
channel being
adjusted.
5. Key
the station
by
setting the
LOC PTT
MUXbus
bit
(A1/D1).
6.
Monitor
the
transmitted deviation level.
7.
Measure the
Trunked Data Deviation level and compare it
to the
requirements of Table
4-8.
If
the
level is out of adjustment,
set
it by adjusting
EEPOT
b.
Refer
to
Chapter
2 ~
Operation for additional information on adjusting EEPOTs.
If the station contains the Simulcast
Operation Option
(C777), measure
the
simulcast data deviation.
EEPOT
b is used
to
adjust the simulcast deviation.
Refer
to
Appendix
H
-
Simulcast
Alignment
for
additional information.
8.
Dekey
the
station
by
clearing
the
LOC PTT
MUXbus bit
(A1/D1).
