No Power
Confirm that the POE Box is plugged into a standard 120 or 220 VAC outlet and
that the small green LED on the POE Box is illuminated. Check that the Sonar-
to-Surface cable is plugged into the
SONAR J1 port on the POE Box.
Improperly connected
In addition to the connections described above, verify that you have a good
cable between the computer Ethernet port and the
PC J2 port on the POE Box.
Bad State
Reset the sonar by removing the POE box AC power cord for 10 seconds. The
sonar head takes ~ 40 seconds to reboot after power is re-applied.
Dirty connectors Make sure that all connector pins are clean and corrosion free.
Improper Ethernet cable
The Sonar Head cabling is conveniently designed so that you can connect your
POE Box to a PC with a
standard Ethernet cable.
However, when connecting your POE Box to a network hub, a crossover
Ethernet cable is required
unless your network hardware is capable of
automatically handling crossed Ethernet cables.
PC networking software is confused
Restart the networking software. There are several ways to do this depending
on your particular operating system: Open the windows network connection
window and right click on the Ethernet connection. Select
repair or disable
then enable . You can also simply restart the computer or cycle the power on
the sonar.
IP subnet masks don’t match
Make sure the subnet mask is the same on both PC and sonar. For the factory
default Class C network configuration, the subnet mask is 255.255.255.0. The
255 defines the
network portion of the IP address. The 0 defines the device
portion of the IP address.
IP network addresses don’t match.
Make sure the IP network part of the IP address is the same on both the sonar
and the computer. In the factory default case, this is the first 3 numbers in the
IP address: 192.168.1.
IP network device addresses are the
same.
The device part of the IP address must be different for every device on the
network. In the factory default case, the sonar is set to 45 and the PC is set to 3.
Do not use 255 as it is reserved for broadcast use.
PC ARP table is stale.
In the ProViewer Sonar Devices window, click the Add button and enter the IP
address you think the sonar is set to respond to, then click OK . The sonar
should respond within several seconds. Alternatively, the PC power can be
cycled to refresh the ARP table.
Poor connection quality
Use an ohm meter to verify Tx and Rx line connectivity between the Ethernet
connector that plugs into the PC and the connector that plugs into the Sonar
Head. Refer to the ProViewer Sonar to Surface Cable Drawing in the Spec sheet
for pin to pin connection information.
