Using Board-Level Ethernet Connection

This is meant to be a work-around for applications that require a board-level Ethernet connection with a
Sentinel V ADCP, or do not allow wireless or touch sensor operation.
Normal maintenance does not require removing the transducer
procedures only if directed to do so by TRDI Field Service personnel.
Sentinel V ADCPs contain Electro Static Sensitive Devices. Take accepted ESD prevention
measures before opening the transducer head.
If the transducer assembly is removed, replace both the desiccant and O-ring.
Never remove the digital recorder SD
board. To recover data, the SD card should be left in the ADCP and accessed using ReadyV.

Open the Transducer

To open the transducer:
1. Follow the directions in
warnings about ESD protection and safety.
2. Lay the transducer on a soft pad in a beams-down orientation.
3. Position the housing in a way so that the internal cable (power and I/O) can reach the cable jack
on the top board. Make sure to secure the housing so that it does not roll.
If the system has an external Ethernet cable, it is not necessary to open the case as shown
below. Rather connect the external Ethernet cable to a powered up laptop. Then repower (or
apply power) to the Sentinel V.

Connecting to the ADCP via Ethernet

To connect to the ADCP via Ethernet:
1. Use an Ethernet cable (CAT 5) to connect to the RJ45 jack on the top board (shown in Figure 70
below). Connect the other end of the cable either directly to a computer or to a router network.
