Connecting the Device Under Test The IT-E255A and IT-E255M quick charger controllers have the same interfaces to connect to the DUT, which provide two kinds of interfaces, namely, USB Type-C and Micro-USB to connect different types of interfaces. Select either sol- id-line connection or dotted-line connection as shown below based on the inter- face type.
2.2 Manual testing The IT-E255M quick charger controller is manual version. During test, the user needs to manually conduct test. The IT-E255A also supports manual test. Tak- ing IT-E255A model as an example, the operation method is described below. Different devices under test support different charging protocols. This series of quick charger controller provides 6 types of protocols including QC2.0, QC3.0,...
