UART / RS‐232 serial remains an important debugging and communication interface for embedded systems and products. Accessing serial data via a PC terminal for testing and debugging is often essential for developers.
Serial to USB converters are now common but most are consumer grade and limited to RS‐232 to USB through either a male or female DB9 connector. In many cases, a gender changer or straight‐thru / null modem cable is required to achieve the correct signaling. Valuable time can be wasted by not having the appropriate connector or inadvertently using the wrong connection.
The Engenuics OEM USB to Serial converter simultaneously addresses all of those issues. RS‐232 connection of either gender or cable type can be used immediately by plugging in to either male or female DB9 connector and adjusting the toggle switch for straight‐thru or null modem connections (lines 2 and 3 are cross‐connected). Level translation is provided on board. Direct UART to USB conversion is also supported using the standard 0.100” header to access Tx, Rx, RTS, CTS, VCC and GND
