Solutions
Incorrect Base coordinates entered.
Specify the correct coordinates for the Base station using PCView or
other suitable field data collection software.
The unit is not configured as a Rover.
Ensure the JNS Gyro-2T has the proper configuration.
The corresponding board(s) options
may be disabled or expired.
See “Checking an OAF” on page 55 for details on how to check
current options.
Enable or prolong the validity of the corresponding options by
ordering a new OAF with the desired options activated.
The elevation mask is above 15
degrees.
Lower the elevation mask.
The board and the antenna have a poor
connection.
Ensure the cable is undamaged.
Check the cable connector attachment to the receiver. Remove and
reattach the cable connector to ensure a secure connection.
A discrepancy exists between the
differential standards used at the Base
and Rover receivers.
Ensure the Base and Rover receivers use the same corrections input/
output format:
Connect your receiver and a computer and start PCView. See
“Connecting the JNSGyro-2T and a Computer” on page 27.
Click
Configuration->Receiver->Ports
and set the same input/
output format for both receivers.
The specified link rate is not compatible
with the link rates the modem supports.
The link rate is the rate at which data
transmits over the RF link.
Change the link rate to that which your modem supports. See the
modem’s manual for link rate support information.
The specified baud rate is not
compatible with the baud rates the
modem supports.
The baud rate is the rate at which the
receiver transmits differential messages
to the modem and vice versa.
Change the baud rate to that which your modem supports. See the
modem’s manual for baud rate support information.
The distance between Base and Rover is
too far.
Close the distance between the Base and Rover.
