KEYSCAN USB-SER USB Communication Adapter

The KEYSCAN USB-SER adapter converts RS-232 and RS-485 signals to USB communication, allowing devices with serial ports to connect to modern computers. It draws power directly from the computer’s USB port, eliminating the need for an external power source.

Compatible with USB 1.1 and 2.0 standards, this adapter includes a 6 ft. (1.8 m) USB extension cable for flexible setup. It is well suited for communication with a single Access Control Unit (ACU) and is especially useful for laptop programming or environments lacking traditional COM ports.
