INSTALLATION
Start by selecting a location for each of the various parts of the system. The
antenna, for example, should be carefully located per the guidelines given below.
Do not route the cables or permanently mount the antenna or receiver yet. Once the
system is operating, then you can route the cables and permanently mount the
receiver and antenna. This way, you won’t have as much trouble if a problem is
found in your initial locations.
INITIAL POWER UP
RPR receivers are reverse power protected so you should not hurt the receiver if
you follow these steps:
Make sure the receiver is not touching any metal surfaces. Place a piece of paper
or something between the receiver and the metal surface if necessary. If you have
the power backwards, a short will exist between the grounded metal surface and the
ground lead (which is power by accident). This short could burn up the ground wire
or blow a fuse. It’s a good idea to isolate the receiver from your chassis the
first time it’s powered up.
Connect the antenna to the receiver but don’t connect any of the other cables.
Right now you should have the antenna temporarily mounted and connected to the RPR.
You should be ready to apply power.
Turn off all the equipment on your machine. The receiver draws very little power
and this test will only take a few minutes. You want the other equipment off
because it might interfere with the receiver. Once you get the RPR working, you
will turn on the other equipment and watch for problems.
Apply power to the receiver. Watch the red LED power indicator. It should light up.
If it does not, you either don’t have power or power is connected backwards. If
you’re in a car, try turning the key on. Check the connections and try again. If
you still have trouble, refer to the Power section below. The yellow RTCM status
LED should blink then go out until a correction signal is located. If the RTCM
status light is flashing rapidly (4 times per second), the antenna cable is either
open or shorted.
Once you have the receiver power connected correctly go ahead and shut the power
off. Mount the receiver and repeat the previous step. If the power does not work
when you mount the receiver then you may have a positive ground system. If so, the
fuse in your machine is probably blown. You will need to isolate the receiver from
your chassis at all times in systems with positive grounds.
At this point, we have the power connected to the mounted receiver and the antenna
is connected. Watch the green LED GPS satellite-tracking indicator. The RPR 110
will be looking for satellites, which may take a few minutes. Eventually, if your
antenna has a clear view of the sky, the GPS light will flash once for each
satellite in view that it is using to calculate its position.
