3.4 Windows Setup
Ethernet Protocol Settings
The Ethernet adapter needs to be setup on the host PC to be in the same IP address range as the sensor being
attached. Using Ethernet comms, allows multiple sensors to be integrated using standard networking equipment.
The TCP/IPv4 network configuration of the host network adapter (PC, SCU or similar) should be set to an IP
address of 192.168.2.xxx with a subnet mask 255.255.255.0. Do not use the IP address for any of the sonar devices
or reserved addresses xxx.2.17, xxx.2.200, xxx.2.201 or the “Obtain an IP address automatically” option.
A minimum 100BASE−TX link is recommended. Ethernet enabled Tritech Systems Require 100Mbps in order to
function correctly and may not work on lower 10BASE−T lines. It’s not recommended to connect Tritech units
through a network hub, a network switch is recommended to be used instead.
Note
A network hub broadcasts to all its ports and thus shares its bandwidth with
each of the ports . If multiple devices are connected then the bandwidth
allocation will be shared between devices, and so the bandwidth per device
will drop.
A network switch records the MAC addresses of the devices connected so
when a frame of data is received the data is sent to the appropriate port rather
than broadcast. This means that each port on a network switch will have the
maximum amount of bandwidth.
Windows Firewall Settings
Check your anti-virus settings. Firewalls will see the data
from the network and may stop the broadcast message.
Occasionally a firewall will allow the broadcast message
but will stop the repetitive, high data rate sonar imagery
packets from the sensor believing it to be a denial of service
attack. If this is the case, to “Allowed Apps” in windows and
add permissions to the firewall settings for Seanet Software.
Serial Comms Setup
COM port allocations vary depending on the computer
you use. They can be found by opening Windows Device
Manager where there is a list of COM ports called Ports
(COM & LPT).
NOTE
When using ARCNET It is worth noting that a SeaHub or Tritech SCU is required
to interface with the sensor. This is because Tritech use our own proprietary
version of the ARCNET protocol.
Wiring diagrams and pin-outs can be found in section 2.6 of this manual.
