1. Use red and black test cables to connect the Load+ and Load- of the quick
charger controller to the anode and cathode of the load’s front panel.
2. Use the twisted-pair cables to connect the Vs+ and Vs- of the quick charger
controller to the Sense+ and Sense- of the load’s rear panel.
3. Use USB communication cable to connect the quick charger controller and
the PC host computer.
4. Use DB9 cable to connect the quick charger controller and the TTL
interface.
5. The quick charger controller is provided with a standard power cord. Please
directly insert the USB Adapter terminal of the power cord to the 220V AC
socket.
6. Insert the Micro USB port of the power cord to the DC input interface of the
quick charger controller’s rear panel.
To ensure the stability of the system, use armored twisted-pair cables be-
tween the remote sense terminals and the equipment under test.
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.
