#  This file includes all the nets from the "P2" connector
#  including the "Z" and "D" columns of this connector.
#  Only the pins in this connector that have signals that are
#  used in the  H-CLK  design have Mentor Graphics  NET  statements.



#  The "Z" Column
#  --------------

NET 'GROUND'  P2-Z2   P2-Z4   P2-Z6   P2-Z8   P2-Z10    # VME-64X ground pin

NET 'GROUND'  P2-Z12  P2-Z14  P2-Z16  P2-Z18  P2-Z20    # VME-64X ground pin

NET 'GROUND'  P2-Z22  P2-Z24  P2-Z26  P2-Z28  P2-Z30    # VME-64X ground pin

NET 'GROUND'  P2-Z32                                    # VME-64X ground pin

#   The  H-CLK  makes no P2 connection to "Z" column odd number pins.




#  The "A" Column
#  --------------
#
#  All "A" Column pins are all "User Defined".
#  H-Clk uses just 2 of these pins to bring the battery backup
#  power supply for the GPS receiver on-card.  This backup supply
#  is assumed to be something like a 9V or 10V rechargable battery.
#  It is fused on-card but also needs to be fuse at the battery.

NET 'GPS_BAT_POS'  P2-A1    # GPS Battery Positive
NET 'GROUND'       P2-A2    # GPS Battery Negative




#  The "B" Column
#  --------------

NET 'GROUND'  P2-B2  P2-B12  P2-B22  P2-B31    # VME ground pin

## ## NET 'VME_5V'  P2-B1  P2-B13          P2-B32    # VME +5 Volt Bus Power

#   The  H-Clk  will get 5V Vcc from the 3 pins on P1 only
#   The  H-CLK  makes no P2 connection to "B" column pins 3:11, 14:21, 23:30.




#  The "C" Column
#  --------------
#
#  All "C" Column pins are user defined.
#  H-Clk does not use any of these pins.





#  The "D" Column
#  --------------

NET 'GROUND'   P2-D31   # VME-64X ground pin  Extended Pin

#   The  H-CLK  makes no P2 connection to "D" column pins 1:30, 32.
