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 head
. Use the following
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 Card
. The digital recorder is located on the top circuit
board. To recover data, the SD card should be left in the ADCP and accessed using ReadyV.
Open the Transducer
To open the transducer:
Removing the Transducer Head Assembly
. Follow all guidelines and
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.
