4.2.8 User Interfaces
There are two types of user interfaces, isolated and non-isolated:
• Isolated interfaces:
- Potentiometer labeled “POT” (R14)
- RESET push button
- PUSH BUTTON (S1)
- PWM OUTPUT enable shunt jumper (J7)
- Communication Port Selection shunt jumper (J2 and J3)
- ICSP programmer/debugger connector for SKDE (J4)
- ICSP programmer/debugger connector for UART-to-USB converter (J1)
• Non-Isolated interfaces:
- 15V Power Supply LED (D17)
- 3.3V Power Supply LED (D18)
- PWM2L1, PWM1L1, PWM1H1, PWM1L2, PWM1H2, PWM1L3, PWM1H3
LEDs
- USB communication LED (D1)
- USB cable connected LED (D3)
- SKDE USB cable connected LED (D21)
- SKDE Power On LED (D19)
- ICSP programmer/debugger connector for dsPIC DSC (J18)
- Feedback Selection Shunt Jumpers J11, J12, J13, and J14.
Table 4-6 shows the multiple feedback signals that can be selected.
