Support and Repair
How do I solve a problem I cannot isolate?
Hemisphere GNSS recommends contacting the dealer first. With their experience with this
product, and other products from Hemisphere GNSS, they should be able to help isolate a
problem. If the issue is beyond the capability or experience of the dealer, Hemisphere GNSS
Technical Support is available from 8:00 AM to 5:00 PM Arizona Standard Time, Monday through
Friday. See “
Technical Support ”.
What do I do if I cannot resolve a problem after trying to diagnose it myself?
Contact your dealer to see if they have any information that may help to solve the problem. They
may be able to provide some in-person assistance. If this is not viable or does not solve the
problem, Hemisphere GNSS Technical Support is available from 8:00 AM to 5:00 PM Arizona
Standard Time, Monday through Friday. See “
Technical Support ”.
Can I contact Hemisphere GNSS Technical Support directly regarding technical problems?
Yes, however, Hemisphere GNSS recommends speaking to the dealer first as they would be the
local support. They may be able to solve the problem quickly, due to proximity and experience
with our equipment.
Power, Communication, and Configuration
My P306/P307 system does not appear to be communicating. What do I do?
This could be one of a few issues:

Examine the P306/P307 cables and connectors for signs of damage or offset.

Ensure the P306/P307 system is properly powered with the correct voltage.

Ensure there is a good connection to the power supply since it is required to terminate
the power input with the connector.

Check the documentation of the receiving device, if not a PC, to ensure the transmit
line from the P306/P307 is connected to the receive line of the other device. Also,
ensure the signal grounds are connected.

If the P306/P307 is connected to a custom or special device, ensure the serial
connection to it does not have any incompatible signal lines present that prevent
proper communication.

Make sure the baud rate of the P306/P307 matches the other device. The other
device must also support an 8-data bit, 1 stop bit, no parity port configuration (8-N-1).
Some devices support different settings that may be user configurable. Ensure the
settings match.

Consult the troubleshooting section of the other device’s documentation to determine
if there may be a problem with the equipment.
Am I able to configure two serial ports with different baud rates?
Yes, all the ports are independent. For example, you may set one port to 4800 and another port to
19200.
