Figure 4: Memory Chip Lockdown

To lock down the memory chip simply solder the jumper in the ’red box’ and cut the trace where the ’red

X’ is. This will lock down the memory chip, thereby not allowing anything to be changed inside it until the
track is restored and the solder jumper is removed.

2 Connections

2.1 Power

WARNINGS

Do not apply any power with reversed polarization.

Do not apply any voltage other than the specified voltage.

Do not use any cables other than the cables supplied by Matrix
Orbital, unless the user is aware of the modifications required.

Do not apply voltage to the DB-9 connector AND power connector

Do not apply more than +5Vdc to pin 9 on the DB-9 connector.

Refer to the diagram below for this chapter.
