4.3.2. ADVField Underwater Canister

There are two connectors on the ADVField underwater canister: one to the probe and the other

for power, serial communications, and auxiliary input / output functions. Underwater mateable

connectors are used for both (some older ADVs used different connectors; contact SonTek if you

have any questions about the connectors used on your system). The high-frequency cable from

the ADVField underwater canister to the probe is a custom-shielded, highly noise-sensitive cable.

Contact SonTek before making any modifications to this cable or connector.

SonTek uses underwater connectors made by Impulse Enterprises. Contact information for Im-

pulse (if ordering items directly) is:

Two different types of connectors are used for power and communications.

• For most autonomous ADVField systems (with internal recorder and battery power):

o The external power and communication connector is a female, 8-pin, underwater mate-

able connector (although some use the female, 16-pin connector described below).

o The bulkhead connector used is an Impulse BH-8-FS.

o The mating connector on the cable is an Impulse IL-8-MP (with locking sleeve).

o Table 18 gives the pin-out for this connector.
