Sonar is present but will not ping
Ensure that you have OpenGL version 2.1 or greater installed.
For Ethernet systems: Check your network settings on the PC. Typing
route print
into the
command line will show the PC routing table. The sonar and PC must be on the same subnet
and the PC’s routing table needs to be set up so that packets are routed correctly to the sonar.
If the sonar is receiving ping requests, then the IP address of the PC will appear in the
Connected IP Address
field in the advanced settings page of the software. If the sonar is
connected to the PC then the most likely cause is particularly bad packet loss on the network
between sonar and PC.
Note
The sonar will only respond to ping requests from IP addresses on the same
subnet as the sonar. Some firewalls have been known to cause this issue.
To view the computers routing table type
route print
from the command
line.
For Serial systems
: When using the Tritech International Ltd USB adapter, ensure that the
Connected LED is fully illuminated and that the Tx and Rx LEDs are flashing. If there is no
LED activity, use the
Device Manager
in
Windows®
to ensure the USB drivers have been
correctly installed.
If using a
direct serial connection
: ensure that the COM Port has been correctly assigned in
the Genesis software and that the baud rate has been set to at least
115200
. Check that the
wire cores have been correctly terminated.
Update rate is slow and there are sometimes large gaps between pings
Check that there is no other software, or service, that is intensively using the network
connection. Run the PC or laptop with just the Gemini software and verify that the unit’s
performance has been improved. There may be noise induced onto the Ethernet cables, be
sure to route these as far away as practicable from noise sources.
Some poor quality PC network cards have problems with the large data rate from the Gemini
sonar and drop a significant amount of packets. If you have large packet loss, try updating
network card drivers and a different brand of network card. Also check that the PC and
graphics chipset meet the minimum spec.
