Bit 1 output	2	Bit 3 output	6
Bit 2 output	3	Bit 4 output	7
Bit 2 output	4	Bit 4 output	8

USER CONFIGURABLE SETTINGS
Setting	Label	Position
Card is Least Significant Nibble	JP1	Pins 2 & 3 closed
Card is Most Significant Nibble	JP1	Pins 1 & 2 closed
Output channels initialized to low state	JP2	Pins 1 & 2 closed
Output channels initialized to high state	JP2	Pins 2 & 3 closed
Note:When a second XO-SRx4 card is connected via J1, one card must be set to the Most Significant Nibble and the other to the Least Significant Nibble.
