Installation Instructions Part 1

39 Chapter 4: Cables and connections
Screen resolution and aspect ratio
Each GPM will output the same screen resolution to all connected
displays.
Therefore where multiple displays are connected to a single GPM
they should have the same aspect ratio and screen resolution. For
example we recommend that wide screen televisions and standard
displays are connected to separate GPMs.
IP Address
When connecting a display to the processor, note its IP address on
your system diagram. You will need to refer to this during the com-
missioning process. (See
Appendix B for sample diagrams.)
Selector Switch
Raymarine G-Series displays have a selector switch located by the
SeaTalk
hs
connector. This must be in the UP position for connec-
tion to the SeaTalk
hs
network.
3rd party displays
Ensure that any 3rd party (non-Raymarine) displays have electrical
isolation between the video connections and power supply (and
any other 0 V referenced connection). This is to avoid 0 V loops
which can cause interference issues.
Marine display cables
The following cables can be used with marine displays:
