Dongle TTL-RS232

PDF datasheet and reference files.

Many electronic devices expose the UART only as logic (TTL) levels. In order to interface with a traditional RS232 port, the signals must be converted to higher, bipolar voltages. That’s what the Dongle does. It can be self-powered with its batteries, or you may include a separate power source. It has digital input and output lines on a terminal block, so any device can be wired in. It also has shunts to change the Dongle from Normal operation to Null modem. The RS232 connector is a standard DSub-9.
