I/O Cable and Dummy Plug

The underwater connector (on the housing) and the I/O cable and dummy plug are molded wet-mate
connectors.
The dummy plug should be installed any time the cable is removed. Use the dummy plug when
the H-ADCP is in storage or is being handled.
When disconnecting or connecting the H-ADCP I/O cable, do not apply any upward force on the
connector. Applying an upward angle as the cable is disconnected or connected puts stress on
the connector. This may cause several serious problems:
a) The connector or connector pins can crack.
b) The O-ring on the bottom of the connector can be damaged.
c) The molded urethane on the connector may separate from the brass insert.
If the connector is damaged in any of these ways, your H-ADCP will flood.
Disconnecting the Cable
To disconnect the cable:
1. Release the retaining strap by pulling it over the connector.
2. Grasp the cable close to the housing (see Figure 5). Your thumb should rest against the edge of the
housing. Do not try to fit your hand under the cable as it passes over the housing. This is what
causes the upward force!
3. Pull the cable straight out away from the housing. Avoid side-to-side rocking motions as much as
possible. Do not apply any upward force on the connector as it is being disconnected.
