Changing the Main Fuse
To change the AC power fuse, you must first unplug
the IEC power cable. This allows access to the fuse
holder. Use a small, flat screwdriver to press into the
notch and pull the holder straight out. There is a
storage place for a spare fuse. Replace the blown
fuse (see picture left) and slide the fuse holder until it
snaps in place.
Figure 4-6. Changing the Fuse
There is also an AC fuse on each of the two boards that make up the power
supply. Each fuse is located next to the AC input connector. These fuses are
accessible by removing the top cover of the Matrix.
RS-232/RS-422 Communications
The Matrix 100 can be controlled by a host system, through an RS-232 or an
RS-422 interface. The interface allows the user to write programs to configure
and automate the operation of the Matrix 100. This includes making changes
dynamically when commanded by the host controller, as well as informing the
host of the Matrix status. Certain important changes in status are reported to the
host automatically. For additional programming information, see Appendix A.
Figure 4-7. Swapping the RS-232/RS-422 Port cable
The rear panel of the matrix has one 9-pin connector labeled RS-232/RS422.
Main Controller board provides two connectors – one for RS-232 and the other
for RS-422. Each matrix ships with the cable connected to the RS-232 port. If
your system uses RS-422, you may change this connection. See page 4-2 for
instructions on removing the Matrix 100 cover.
9-Pin Communication Connector
The RS-232/422 connector is a
standard 9-pin D female with the
following pin designations:
