MX525A Mounting
The MX525A console is not weather-resistant and must
be located inside the equipment room or pilot house
where it is dry and protected from the elements. Provide
ample clearance around it for good air circulation. Use
the supplied mounting bracket kit to mount it on a
vertical wall.
Locate the MX525A within 3 meters from the MX CDU
junction box. Should there be a need to install the
MX525A much farther away from the MX420 CDU, a
longer cable assembly can be specially ordered from
Simrad.
The MGL-4 antenna is a weather resistant unit and should
be mounted in the open location as shown in the antenna
location diagram.
Below is a list of power-data cable options available from
Simrad:

MX525A Connectors

namely:

code. The chart also compares the signal interface of
