Wait for the receiver to find and track the WAAS signal, it could take 15 or more

minutes before the receiver gets the necessary almanac data from the selected WAAS

satellite. This initial startup time is necessary only during the first time you

use the receiver.  Once the broadcast is found the receiver will power up and start

receiving signals after about 5 seconds. If you don’t get a signal within about 30

minutes there could be some form of interference or you may not be in the coverage

area of the selected WAAS satellite.  You should see the RTCM light come on and

remain steady if your getting corrections.

At this point, your receiver should be tracking satellites and generating good

differential positions.  Start turning on the other equipment on your machine. As

each device is turned on, watch the LED status indicators for problems. A device

could interfere with the GPS satellites or WAAS signals. You should wait about 30

seconds after each device is turned on to see if the receiver stops tracking

satellites or if the RTCM indicator goes out. Finally, start up the machine and

again watch for any problems.

If after you turn something on, a problem is found, you can try moving the antenna

further away from that device. Check that the device is functioning properly and

also check its power connections.  Some devices can generate too much noise

naturally or because of defective components.

Now you have the receiver working with everything that could interfere.  Shut

everything off, mount the antenna, and route the cables.  Once this is done, repeat

the power up steps.

The last few steps deal with connecting the other equipment that gets data from the

RPR 110.  Refer to the manufacturer’s documentation for details such as baud rates

and required messages.  It is very likely that you only need to connect the

interface cable to the device.  The RPR 110 is configured, by default, to work with

most systems without any adjustments.

All configuration and WAAS data is stored in non-volatile memory inside the RPR

110. If you need to change the WAAS or GPS setups, you can run the receiver software

to make the changes.

POWER

The RPR 110 receiver needs DC power between 9 and 16 Volts.  DC power is usually

provided by a battery on the machine or via a power adapter of some type.  If your

unit came with an automotive power adapter, verify that your vehicle has a negative

ground system before you connect to power.  If your unit came with an AC adapter,

you need only connect the adapter to an AC source.

GPS ANTENNA

GPS is a line-of-sight system, which means in order for the receiver to track the

satellites there must be an unobstructed path directly to them.  Buildings, trees,

machinery, and human bodies are common obstructions.  When locating the antenna,

find a place where the antenna will have an unobstructed view of the sky.
