  • *1: Refer to the WIZ750SR Command Manual.
    The prerequisite for the transition to Command mode is that the HW_TRIG signal is not used while the Command mode switch code is used.

    To prevent the WIZ750SR from automatically connecting to the network before executing the Command mode switch code, add a pull-down resistor of 2KΩ to the HW_TRIG signal.
    ex) Connect 2KΩ between NODE2-pin 8 and NODE2-pin 26.

Short Plug


JP1 / JP2 / JP3

To use Pmod UART devices that support Pmod Interface Type 3 (UART), Pmod Interface Type 4 (UART), and Pmod Interface Type 4 (extension UART), the following short plug settings are required.

To use as Pmod Interface Type 3 (UART), connect the short plug JP1/JP2/JP3 to Type3 side.
To use as Pmod Interface Type 4 (UART) or Pmod Interface Type 4 (extension UART), connect the short plug JP1/JP2/JP3 to Type4 side.

The following is an example of the Type3 setting:


JP No.Configuration
JP1
JP2
JP3
1-2: Type4
To use a device that supports Pmod Interface Type4 (UART) or Pmod Interface Type4 (extension UART)
2-3: Type3 (default)
To use a device that supports Pmod Interface Type3 (UART)


JP4 / JP5 / JP6

The connector board is mounted with a USB-UART conversion IC, which enables USB data communication.

If USB data communication is not to be used, or if the module's NODE2_UART is intended to be used, the USB-UART converter IC can be isolated from the circuit by removing the short plug JP4/JP5/JP6.


JP No.Configuration
JP4Open: Does not connect the power supply terminal of USB-UART conversion IC and VBUS.
Close: Connects the power supply terminal of USB-UART conversion IC and VBUS. (default)
JP5Open: Does not connect the TXD of the USB-UART converter IC and the NODE2_UART_RX of the module.
Close: Connects the TXD of the USB-UART converter IC and the NODE2_UART_RX of the module. (default)
JP6Open: Does not connect the RXD of the USB-UART converter IC and the NODE2_UART_TX of the module.
Close: Connects the RXD of the USB-UART converter IC and the NODE2_UART_TX of the module. (default)

Method for inserting and removing a module

Ensure that the following steps are performed with the power off.

Inserting a module

Insert the module into the connector board.

Align the module pins with the connector board pin sockets ensuring that there is no misalignment, and push both edges of the module with equal force.
Before turning on the power, check once again for misalignment of the pins.

Removing a module

Remove the module from the connector board.
The module and the connector board are firmly connected by pin sockets.

While holding down the connector board, slowly and gradually move the module up and down, lifting it up to remove it from the pin sockets. Please note that the pins may be bent if removed forcibly.
