The following sections detail the display unit connectors used when installing
a single
hsb
2
Plus Series LCD Display. The remaining connector details are
provided in Section 2.7.
Transducer Connection (master displays)
The transducer cable connector (and Y-shaped connector, if supplied) has a
nut that has been removed to aid installation. To allow you to complete the
installation without cutting the cable, ensure that any holes you drill are large
enough to accept the connector, with the nut removed (approximately 13/16"
or 21 mm).
Before attaching the transducer cable, you will need to attach the connector
nut and split ring. These items, plus a wedge tool, are included in the
transducer packaging.
The transducer cable is attached to the 7 pin male connector marked
TRANSDUCER on the rear of the display unit. How you connect the cable to the
display unit depends on the type of transducer you have installed:
