GHI Electronics,LLC USBwiz User Manual

Getting Started with USBwiz

5. Getting Started with USBwiz

The following chapter give simple steps to get USBwiz working for first time user and that

is through UART interface.

All you need:

● USBwiz OEM board

● RS232 adapter connected to UART Tx/Rx and connected to PC COMx

● PC COMx access through a terminal program

● USBwiz latest firmware

Step-by-Step:

1. confirm that all hardware connections are made:

○ MODE pins are set to UART mode

○ Power is connected

○ RS232 adapter signals connections and let's assume it is connected to PC

COM4. If CTS and RTS signals are not available, user can ground CTS. Note

that USBwiz and the OEM boards are TTL levels and UART signals are 0V to

5V, but the PC is RS232 -12V to 12V, therefore, you need a RS232 circuit.

There are some RS232 converters available such as MAX3232. See

schematic below:
