devices (ZGP800A GPS antenna and ZRT100 radio) to carry out general RTK sur-
veying
Also provided is a couple of pointers on how to find and fix issues that you may
have
Devices may be configured to the ZGP800C via cables or using a Bluetooth con-
nection This document will concentrate on using Bluetooth Once the ZGP800C
is configured these settings will stay until configuration is changed i e the Blue-
tooth will connect automatically to the antenna once turned on

Tips or Bluetooth
The status of the Bluetooth connections can be checked by selecting the Blue-
tooth icon at the top of the screen This tells you what devices are attached to
which port If they are black then they are currently connected If they are gray
then they are not connected There are three Bluetooth ports and each one is
configured for a particular device
Port 1: Rover antenna,
Port 2: Reference antenna
Port 3: Bluetooth radio
Note that the first time you connect to a Bluetooth device it will ask for authenti-
cation The PIN is “0000” If it is the first time connecting to the Bluetooth device
it may take a few seconds to complete the connection
The Bluetooth connections can also be checked checking the Blue LED at the top
of the ZRT100 and ZGP800a
USB cable: If the communication to the antenna is via the USB cable then the
1 2m cable with red markings needs to be attached between the ZGP800C and
the ZGP800A “USB cable” need to be selected in Instrument Con ig > An-
tenna.
Issues
(A) Re erence antenna connected as a rover
If a Bluetooth connection is active on a device then that device will not be visible
when searching for a Bluetooth device Therefore if your ZGP800A is connected
as a rover you will not be able to search it as a reference antenna Turn on the
rover antenna and within “Antenna Configuration” for the rover establish the
connection to the correct antenna

5/5
It is advisable to distinguish each GPS antenna from each other, by writing the
serial number in a visibly on the casing.
If you are carrying out a lot of RTK surveys then make one antenna the refer-
ence antenna and the other the rover antenna Therefore your rover Bluetooth
connection is always configured to the correct antenna – save time configuring
A ZGP800A set as a reference once turned on will use the previous configured
information and send out corrections – this allows the user to set up the refer-
ence on the same mark without going through the “Setup Reference” program
Breaking Bluetooth connections
If you find you can not solve any Bluetooth problems and you want to break all
Bluetooth connection you can do this in the Windows “Bluetooth Manager”
Minimise the ZGP800 software Main Menu –Shi t- MIN and then open the
“Bluetooth Manager” from the “Control Panel” Select each of the “Trusted”
Bluetooth connections and move them to the “Untrusted” folder Then press
“ok”
All Bluetooth connections will now have to be setup again This includes Blue-
tooth authentication
