Antenna Configuration (Image 4)
Antenna configuration is only for the “rover” GPS antenna – this antenna is con-
nected permanently to the ZGP800C. The reference antenna is configured in the
“Setup Reference” Program.
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. Once “USB cable” is selected select CONT (F1).
Bluetooth – When using the Bluetooth for the first time you will need to search
for the Bluetooth device – “SRCH” (F4). Select the ZGP800A from the list and
press “CONT” (F1) (Image 5). This returns you to the previous screen, now press
“CONT” (F1). If it is the first time connecting to the Bluetooth device it may take
a few seconds to complete the connection. The connection can be checked by
selecting the Bluetooth icon at the top of the screen or the Bluetooth light illumi-
nated blue on the ZGP800A.
Issues
Reference 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.
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” (Im-
age 8). Minimise the ZGP800 software (Image 6) and then open the “Bluetooth
Manager” from the “Control Panel” (Image 7). Select each of the “Trusted” Blue-
tooth connections and move them to the “Untrusted” folder. Then press “ok”.
All Bluetooth connections will now have to be setup. This includes Bluetooth au-
thentication (Image 2).
