2.11 D/A Reference Voltage Setting
The D/A converter's reference voltage source can be internally or externally 
generated. The external reference voltage is connected via CN3 pin 
31(ExtRef1) and pin 12(ExtRef2), see section 3.1. The D/A reference source 
of channel 1 and channel 2 are selected using JP2 for the ACL-8112DG/HG 
and JP6 and JP7 for the ACL-8112PG respectively. Possible settings are 
shown below:
