ATTENTION: Do not plug in the data recorder end of the cable
(Catalog No. 2706-NC4) until the Industrial Terminal cable is
unplugged. If both cables are plugged in at the same time, the
DL20 may be damaged.
1. Connect the 2706-NC4 cable to the DL20 as shown. Do not connect the
other end of the 2706-NC4 Cable to the 1770-SB until the Industrial
