Using Ethernet Communications
Sentinel V Real-Time systems, starting in May 2017 supports Ethernet output. These systems must be fac-
tory configured or field upgraded. Ethernet systems can be identified by the model number, such as
S20-53PEWR-16G-200, where E stands for Ethernet.
Ethernet can be used for following scenarios:
•
Send commands to the ADCP and receive responses on the CMD channel. The CMD channel is
used to connect to a Sentinel V RT system and control it using a two-letter command system and
must use port 9000. Use Sentinel V RT Utilities software to connect to this port using TCP proto-
cols to control the Sentinel V RT system.
•
Send data from the ADCP to user equipment such as a PC or a data logging device. The data
channel is established over a UDP socket.
UDP Data Output
– It is possible to output ensemble data in two ways over a UDP connection:
•
Send ensemble data to a specific destination IP and port number, known as
•
Send ensemble data to a network directed broadcast IP and port number, network directed

RT Utilities Software help file.
If you have problems sending data over UDP, check the Windows® Firewall is not blocking
Sentinel V RT Utilities
. See
for more information.
Using Directed UDP Output
For directed UDP output, the following parameters are required:
•
Destination IP address of the remote machine
•
Destination Port Number of the remote machine
UDP is a connection-less protocol. Therefore, UDP packets can be lost in an unreliable or
highly congested network.
To view Directed UDP data over the Ethernet:
1. Use the Data Output box to set the Destination IP address for Data Output. Click on the
Change button.
2. Select Peer to Peer or Broadcast (Manual). Enter the Destination IP address. Change the
destination Port as needed. Click Set.
3. Wait 10 to 15 seconds before deploying the ADCP using the Deploy button.
