3.4.5. Optional third party Video Check
Check the Video communications operation by moving an object in front of the camera and
ensure the picture in the video window is updating correctly and no distortion is present.
3.5. Hardware Reset
Important
The procedures outlined below involve opening the unit and appropriate
precautions should be in place to protect against static discharge while carrying
out this operation.
It is possible to lose communication with the surface MicronNav100 Interface Hub if the baud
rate of the SeaHubMain port is taken too low (this is now only adjustable in Supervisor mode),
the only way to recover from this is to perform a hardware reset on the unit to reinstate the
default settings. This can only be done by opening the MicronNav100 Hub.
Caution
Before attempting this procedure ensure that the unit is disconnected from the
AC and DC power source, and all other devices are disconnected from it.
Using a 2.5mm Hexagonal (Allen) key unscrew the two screws on the front panel of the unit
and carefully remove the front panel assembly from the unit, the lid can then be removed by
sliding forward out of its guides.
This will now give access to the DIL switch under the front edge of the plug-in daughter board,
SW2 will be set to the ON position and SW1 & SW3-SW6 will be set to the OFF position. To
perform the reset operation change SW1 to the ON position, re-fit the lid and front panel and
apply power to the unit for about 10 seconds.
To complete the reset operation disconnect the unit from the power supply, re-open the
housing as above, set switch 1 back to the OFF position and reassemble the unit. Note: If
this is not done the unit will not be able to store any new settings.
