DSX Access System DSX-1040PNV Installation Instructions

DSX-1040PNV Installation
The DSX‐1040PNV non‐volatile memory processor is a
replacement processor that provides a layer of
resiliency to any existing DSX system. The processor will
retain its memory and allow a controller to be
immediately operational upon power up without the
need for a download from the DSX Communications
Server.
The DSX‐1040PNV Processor can be installed on all DSX‐
1040 Series and all DSX‐1022 Controllers. It can also be
installed on 1030PR5 Retrofit Processors. Once this
processor is installed on the Master Controller, it will
become operational on power up and if called upon,
will download any subsequent Sub Controllers providing
them with the data required to make them fully
operational. In addition, this processor can be installed
on any or all Sub Controllers in the same Location to
provide even further operational resiliency.
Reset ‐ NonVolatile Memory Procedure
1. Power down the Controller
2. Change the Dipswitch setting (change switch 1)
3. Power up the Controller (Alive LED flashes)
4. Power down the Controller
5. Change the Dipswitch back to correct settings
6. Power up the Controller
DSX‐1040PNV on 1040 Series
1. Disconnect Power from the Controller that you are
to install this processor on.
2. Remove all field wiring using the removable terminal
blocks.
3. Remove the three mounting screws that secure the
board to the mounting rails of the enclosure.
4. Carefully remove the shield from the circuit board.
Older metal shields will need to be pried up on the four

left off or the bottom can be left unsecured. Plastic
shields can be pulled up at each securing anchor and
can be reattached when finished.
5. Locate the small daughter board (processor) on top
of the I/O board. Gently pull straight up on each side
slowly until the old processor has been unseated.
6. Line up the new processor with the row of male and
female pins and gently push the new processor down
until seated.
7. Reattach the plastic shield. For a metal shield, leave
it unsecure at the bottom nearest the terminal blocks or
leave it completely off.
8. Using the three mounting screws reattach the
controller to the enclosure mounting rails.
9. Reconnect the removable terminal blocks and field
wiring except for power.
10. Power the controller up and make sure the Alive LED
starts to flash normally.
11. Force a Full Download to the controller.
Note: Use these same instructions as the basic guideline
for installing a DSX‐1040PNV on DSX‐1043 and DSX‐
1044 Controllers.
DSX‐1040PNV on DSX‐1022/20
The DSX‐1040PNV can be installed on the DSX‐1022
Intelligent Controller and on the 1030PR5 Retrofit
Processor for the 1030 Series Controllers.
Use these instructions for the for the DSX‐1022.
1. Disconnect Power from the controller that you are
going to install this processor on.
