MX 420 Installation and Service Manual
Each of these techniques are described below. All the hardware necessary to com-
plete the Flush and Gimbal mount is provided with the MX420. You will need rear panel
access to complete these types of mounts. The Frame mount is an option for applica-
tions where front panel removal is not desired or rear panel access is not available.
The hardware necessary for the Frame mount is sold separately (P/ N 715707). It is
important to consider the space behind the unit to prevent sharp cable bends before
commencing with the installation. A minimum of 100 mm. free space is needed behind
the unit for cable dressing.
Gimbal Mounting
A pivot Mounting Bracket including finger screws and rubber friction washers are
delivered with the MX420. Place the self-adhesive rubber washers around the two
threaded holes at each side of the navigator. Use the two machine screws with the
large palm grips to secure the MX420 to the mounting bracket. Adjust the viewing angle
to meet your needs.
Flush Mounting
Drilling and cutting instructions for flush mounting are given in Figure 3.3. The maximum
bulkhead thickness which can be used in this configuration is 9 mm (7/ 16 in). Cut a
notch deep enough to accommodate the flush mount bracket, Allen head bolt, and Allen
key for thicker bulkheads
Flush Mount Frame
If access to tighten the screws from the backside is impossible, an optional Flush
Mounting Frame is available (P/ N 715707). First, mount the frame to the navigator.
Next, attach all of the hardware interfaces to the appropriate port (i. e. Cable A, B & C).
Finally, mount the entire assembly to the panel from the display side. The frame is
oversized ( 300 mm x 175 mm; 11.81 in x 6.89 in). The frame mount hole cut dimensions
are given in Figure 3.5.
Turning Power On and Off
The navigator is turned on by briefly pressing the
key. Please do not keep the key
pressed for more than one second, as this will turn the navigator off again when the
key is released. This key is also used to turn the power off by either of two methods:
a) Software Control:
A normal short key press displays the softkey option boxes
Yes
or
No
to turn the
power off. Respond by pressing the
Yes
softkey under the box turns the navigator
off. Selecting
No
cancels the operation, and returns the unit to normal operation.
b) Hardware Control:
Pressing the power key for more than 3 seconds, turns the power off under
hardware control (the softkey option will also be displayed under normal operating
conditions). The MX420 can not be turned on again for 10 seconds when this
method is used. Attempting to turn the unit on during this 10 second period, will only
activate the navigator for as long as the key is not released. This option is not
normally used, and is provided as an emergency alternative to the software power
control.
