4.4.2.3
To enable the USB OTG mode:
1. Install jumper J5.
2. Remove jumpers J6 and J7.
3. To detect the status of the regulated output voltage of the charge pump, connect
4. To have software control of the charge pump, connect the SHDN signal to the
In USB OTG mode, use J7 (Type Micro AB Female USB connector) to connect with
external USB OTG devices.
4.4.3
The development board provides one UART, with its RX and TX signals appearing on
pins RD0 and RF3 of the PIC24FJ256DA210, respectively. The signals can be
configured to appear at one of two places:
• The RS-232 external serial port (default).
• The PICtail Plus connector, as signals U1RX (pin 2) and U1TX (pin 4).
An RS-232 level shifter (U3) has been provided with all necessary hardware to support
the external serial port. The DB-9F serial connector (P1) is wired to support hardware
flow control; however, the flow control signals are not connected to the microcontroller.
The port is configured as a Data Communication Equipment (DCE) device.
The UART’s availability is configured by jumpers JP16 and JP17. Their location is
shown in Figure 4-5.
To access the UART through the RS-232 serial port:
1. Set jumper J16 to position 1-2 (USART_TX – TX) (default).
2. Set jumper J17 to position 1-2 (USART_RX – RX) (default).
In this configuration, a host PC running the appropriate application can communicate
with the development board using the serial channel. Use a standard
(“straight-through”) serial cable connected to P1.
To access the UART through the PICtail Plus expansion port:
1. Set jumper J16 to position 2-3 (U1TX – TX).
2. Set jumper J17 to position 2-3 (U1RX – RX).
In this configuration, the U1RX and U1TX signals appear at pins 2 and 4 of the PICtail
Plus connector, respectively.

Note:
the charge pump PGOOD signal to the microcontroller (Figure 4-4, callout 3):
a) Remove jumper JP14 (disconnects CTMU_PAD2, LED D2 and switch S2).
b) Populate resistor R32 with a
microcontroller (Figure 4-4, callout 3):
a) Remove jumper JP15 (disconnects the potentiometer, switch S3,
b) Populate resistor R45 with a
AN21/RE9).

USB ON-THE-GO (OTG) MODE
UART (RS-232)
Enabling USB OTG mode may require the remapping of the UART’s TX
signal. See Section 4.4.3.1 “UART and USB OTG Mode (TX Remap-
ping)” for more information.
The TX and RX signals are mapped to the microcontroller pins using the
Peripheral Pin Select (PPS) feature. When developing applications, make
sure that the pins are remapped properly to use the UART Receive and
UART Transmit signals. Refer to Section 10.4 “Peripheral Pin Select” of
the PIC24FJ256DA210 data sheet for a detailed discussion of PPS.
