Effective number of satellites are total number of sat-
ellites tracked minus the number of non-GPS systems
tracked. E.g. if 8 GPS and 5 GLONASS are tracked the
effective number of satellites is 12.
The REC (record) LED displays the data recording
status and blinks on each recording.
•
Green – recording data.
•
Yellow – less than 10 min memory left.
•
Red – memory is full.
•
No light - not active.
The On/Off (power) button turns the receiver on and
off.
The FN button starts/stops data recording.
Data and power ports
The DELTA receiver can be equipped according us-
ers needs and have different ports on the front and back
panels.
Below are presented some examples of possible con-
figurations:
Figure 4.
DELTA Ports
•
Power – used to connect the receiver to an exter-
nal power source. This port can also be used to
charge the batteries.
•
Serial – used for communication between the re-
ceiver and an external device.
•
Ethernet - used to connect the receiver to local
network.
•
USB –used for high-speed data transfer and com-
munication between the receiver and an external
device.
The DELTA-3 receiver can be equipped according
users need and have different connectors on the back
panel. Below are presented some examples of possible
configurations:
•
The external GNSS antenna connects to the TNC
external antenna connector (optional)
•
The 1PPS and Event marker BNC connectors (up
to two) (optional)
•
External Frequency Input/Output BNC connec-
tor (optional)
Turning On/Off
To turn ON the receiver, press and hold the power
button until the LEDs briefly flash. To turn OFF the re
-
ceiver, press and hold the power button for more than
one and less than four seconds (until both the SAT and
the REC LEDs are off). This delay (about 1 second)
will prevent the receiver from being turned off by mis-
take.
DELTA-3 saves the last power status and restore it
after voltage loss.
Power supply requirements
The socket-outlet shall be installed near the equip-
ment and shall be easily accessible.
A single external power supply with 5 pin ODU
connector or SAE connector is necessary to operate
DELTA-3. If external power supply has only SAE con-
nector, Receiver-to-SAE power cable shall be used. The
external power supply needs to be Listed for US and
Certified for EU countries, it needs also to be a Limited
Power Source and have an output rated for 14.5 - 35
V DC, 2A. This may not be the same range as other
JAVAD GNSS products with which you are familiar.
To avoid the introduction of hazards when operating
and installing, before connecting of the equipment to
the supply, make sure that the supply meets local and
national safety ordinances and matches the equipment’s
voltage and current requirements.
Warning:
Never attempt any maintenance or cleaning of the
supply while plugged in. Always remove supply from AC power
before attempting service or cleaning.
If the voltage supplied is below the minimum speci-
fication, the receiver will suspend operation. If the volt
-
age supplied is above the maximum specification, the
receiver may be permanently damaged, voiding your
warranty.
Make sure cords are located so that will not be stepped
on, tripped over, or otherwise subjected to damage or
stress. Do not operate equipment with a damaged cord
or plug – replace immediately. To reduce the risk of
damage to the equipment, pull by the plug body rather
