The ATC-102 is an extremely low cost device for interface conversion from RS232 to TTL (3.3V or 5V). The converter is directly plugged into the DB9-M connector on the DTE port and provides an RS485 interface on DB9M/clamps. The device is powered directly from the RS232 port so no external power supply is needed.
