2 Installation
The ATS-6501 provides a number of features which may require additional setup and this section
provides a guideline for the basic setup. After completing this section, the ATS-6501 will
produce timing outputs to the coarse calibration accuracies specified in Appendix A. The ATS-
6501 is designed to be quickly and easily integrated with other system components. Just a few
steps are required in setting up the system so that it will begin producing accurate timing outputs.
In order to set the system up, users will need to power up the system and set up communications
in order to have access to the system command port.
2.1 Powering on the ATS-6501
Apply power to the system by supplying input power to at least one of the two power supplies.
When power is applied to the ATS-6501 the front panel will go through a self-test and then the
ATS-6501 will begin booting up.
Note:
If power is applied to both power supplies the Status Indicator on the front panel of both
power supplies should be green. If power is applied to only one of the two supplies the power
supply without input power should have a red Status Indicator and the units Alarm Indicator
should be red.
Note:
The ATS-6501 front panel Power-On Self-Test (POST) will occur even if the front panel
software flash is removed.
A.
The Date/Time display will sequentially test each segment on each individual position
within the display. On the SAASM receiver version, the KEYED LED will blink quickly
to indicate self-test, then either turn off or green to indicate the receiver’s Key status.
B.
One at a time, each position of the display will display the number 8 starting from the far
left and working to the right.
C.
Each LED below the Date/Time Display (Alarm, Oscillator Locked, GPS Tracking, NTP
Locked, & Outputs Enabled) will be turned on one at a time starting from the left to right.
As each LED is tested it will be green, then red, and then turn off with the exception of
the GPS Tracking indicator, this indicator will turn red, then green, then off.
D.
The Date/Time display will then display “-9876543210” on the front panel.
E.
Lastly the Date/Time display will have a “-” in the center of each position in the display.
F.
When the unit starts the application, the Oscillator Lock, GPS Tracking, and NTP Locked
indicators will turn red momentarily then go out.
G.
While the ATS-6501 is booting up and waiting for the internal oscillator to lock the LED
indicators on the front panel below the Date/Time display should be off and the bars in
the display after the POST will move to the top, then center, then bottom and then go out.
This display will repeat as long as the unit is not tracking GPS.
Caution:
The default antenna supply voltage is
ZERO
. If the antenna requires power from the
ATS-6501 to operate the system will stay in this mode until the antenna is properly configured.
This prevents the system from potentially damaging any antennas until the antenna supply voltage
is set properly by the end user.
As the ATS-6501 warms up, the Oscillator Lock indicator should come on within 5 minutes after
the system is turned on. The Alarm light may remain on until the Outputs are enabled. This is
normal and does not indicate there is a problem with the unit.
