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:
