Terasic GPIO-HTC Card schematic

Dear all

I'm trying to use GPIO-HSTC card with DE2-115 board but can't find any clear document about "DE2-115 FPGA pin <-> GPIO-HSTC card J2/J3/J4 pin" connection.

Does anybody have card schematic or DE2-115 FPGA pin assignments for GPIO-HSTC card?

Thanks in advance

PS: in GPIO-HSTC card User Manual the connection names of HSTC Connector (Fig. 3.1) don't match with J2/J3/J4 pin names (Fig. 3.2 and 3.3)
