* R6 and R7 can be used to shift the address of the 64 bit version of the card from 0x20-0x23 up to 0x24-0x27
 
* R6 and R7 can be used to shift the address of the 64 bit version of the card from 0x20-0x23 up to 0x24-0x27
* R6 pulls up A2 to Vcc (only if R7 is not installed) (64-bits only)
+
** Clip out R7 jumper to shift address up (not typical use)
* R7 provide pull-up or pull-down for I2C address A2 line
 
 
 
=== DIGIO-128 - 128-bit option ===
 
 
 
* Leave R6 open (no resistor)
 
* Install jumper wire into R7
 
 
 
=== DIGIO-64 - 64-bit option ===
 
 
 
* Typical - for I2C address = 0x20-0x23 leave R6 open, install jumper wire into R7
 
* For I2C address = 0x24-0x27 leave R7 open, install 10K resistor in R6
 
* I2C chips get installed into top 4 locations
