on your PC or into an available USB port on an USB hub. Connect the

other Type-B end to the rear Type-B connector of this Module Box.

2. The Module Box is powered by the 2-pin terminal blocks instead of the

USB bus, please connect the +7~12V DC power (not provided with this

product) for proper operation (the polarity must be applied correctly). If

you have another USB device need to be connected with daisy-chain

mode, please connect it to the USB Type-A downstream connector.

3. If you are connecting a RS232 device to the Module Box, then the 3

RS232 pins on the terminal blocks are required. The RS232 mode does not

need any extra DIP switch settings, simply connect to the terminal blocks’

pin 5, 6 and 7 and left the rest pin 1~4 unconnected. Each port can only

work in one mode at the same time. The RS232 mode is not set by DIP

switches. Instead, it is automatically supported by the separate

connector pins.
