Keyscan USB-SER USB Communication Adapter

Easily connect legacy controllers, readers and keypads to modern computers with the Keyscan by dormakaba USB-SER USB Communication Adapter. Designed for technicians and integrators, this compact USB communication adapter converts both RS-232 and RS-485 signals to USB so you can program, monitor, or troubleshoot access control systems even when a serial COM port is unavailable.
