RTM Reset
Pushbutton (SW1)
Mounted on the RTM face plate, SW1 is a normally-open, momentary contact switch used to
reset the CHAMP-AV8. The other PWB-mounted switches (see Table A.39 on page A-57) are
toggle switches that will stay in the position set.

ONNECTORS
As seen in Figure A.19 on page A-53, the RTM PWB provides a group of headers on the PWB,
numbered JB1 through JB8. These headers provide (for example) access to the Discrete I/O
(DIO), PMC I/O, XMC I/O. With the increased accessibility afforded by the RTM, these
interfaces become available for probing, wire-wrapping or attaching a cable for debug, as well
as connections to other parts of the system.
SW17
SOFT_JUMP0
The SOFT_JUMP0 and SOFT_JUMP1 switches on the
RTM (which correspond to jumpers JB2 and JB3, respec-
tively) are software readable, and can be used by software
programs to branch logic in any way desirable by the pro-
grammer. These settings have no effect unless they are
assigned a specific meaning or decision choice within a
program.

Caution
See the
Software User’s Manual, VPX6-460 BIOS
, document number 826450, for additional
information describing the various boot modes and the operation of the SW0 and SW1
software jumpers. Jumper settings may be viewed using the BSP; refer to
“sysBoardInfoShow()” and “sysJumperStateGet()” in the Software User’s Manual,
CHAMP-AV8 VxWorks BSP & Driver Suite, document number 826452, or in the Software
User’s Manual, CHAMP-AV8 Linux BSP & Driver Suite, document number 826449.
The SW16 switch is intended for factory use only, and as such should be left in the Off
position, to avoid over-writing the contents of the PABS.
Note
Referring to Table A.39, when an RTM switch has a corresponding CHAMP-AV8 on-board
jumper, either can affect the function. If either the switch is ON (closed) or the jumper is
INSTALLED, or both, the non-default setting is selected.
Note
The NVMRO switch on the CHAMP-AV8's RTM has the opposite polarity when compared to
the VITA 46 Specification. In other words, according to the VITA 46 spec, when a NVMRO
jumper is installed (or the switch is closed), the non-volatile memories are write protected.
On the CHAMP-AV8, when SW12 is closed the non-volatile memories are writable.
