Ethernet device connection Ethernet is used to connect 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 crossover 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 fitted with 5 ethernet ports.  Note: When designing a system, take in to account the ports 'lost' when used for linking multiple NEP-2 modules together.

HDS Gen3 Installation Manual
Ethernet device connection
Ethernet is used to connect 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 fitted
with 5 ethernet ports.
Note:
When designing a system, take in to account the ports ‘lost’
when used for linking multiple NEP-2 modules together.
