Connect Tech FreeForm/PCI-104 User Manual
Revision 0.07 37
Hardware Description
Connector Pinouts
High-speed Serial (P4)
The sideband LVCMOS signals (HSS) have been rearranged so that when two FreeForm units are
connected:
HSS_USER_IO(0) maps to HSS_USER_IO(2)
HSS_USER_IO(1) maps to HSS_USER_IO(3)
Also, 3.3V pins replace the GND pins; this is because the connector has embedded GND blades.
RS-485 Headers (P5)
The orientation of the connector has changed. The pinout remains the same.
