Dc590 or Dc2026 Quick start proceDure
IMPORTANT! To avoid damage to the DC2222A, make
sure that JP6 of the DC590 or JP3 of the DC2026 is set
to 3.3V before connecting to the DC2222A.
VCCIO (JP3) of the DC2222A should be in the 3.3V posi-
tion for DC590 or DC2026 (QuikEval) operation. To use a
QuikEval controller with the DC2222A, it is necessary to
apply –9V and ground to the –9V and GND terminals. 9V
for the DC2222A is provided by the QuikEval controller.
Connect the QuikEval controller to a host PC with a stan-
dard USB A/B cable. Connect the DC2222A to a QuikEval

controller using the supplied 14-conductor ribbon cable.
(Do not connect both a QuikEval and PScope controller
at the same time.) Apply a signal source to J4 and J2. No
clock signal is necessary at J1 when using a QuikEval con-
troller. The clock signal is provided through the QuikEval
connector (J3).
Run the QuikEval software (version K109 or later) supplied
with the QuikEval controller or download it from
