Ethernet device connection
Ethernet is used to interconnect high bandwidth devices such as
radar, sonar, and other displays. The HDS-7 display has one ethernet
port, whereas the HDS-9 and 12 displays have two. Navico ethernet
cables have a locking collar, for maintaining a reliable, waterproof
connection.
Connecting directly to a single device
The ethernet port is auto sensing, meaning that the unit can
connect to one network device directly, without the use of a cross-
over cable or switch.
Connecting to multiple devices
If connecting more than one ethernet device to a HDS-7 display, or
two devices to a HDS-9 or HDS-12 display, use the optional network
expansion Port (NEP-2).
If the number of ethernet devices exceeds the number of available
ports on the NEP-2, it is possible to link two or more NEP-2 modules
together to provide the required ports. The NEP-2 modules are tted
with 5 ethernet ports. See page 31 for cable options.
¼ Note: When designing a system, take in to account the ports ‘lost’
when used for linking multiple NEP-2 modules together.
