Details

The PathWay® Model 4520 is a DB15 Interface A/B Switch. Each of the A, B, and COMMON ports are DB15/female. The M4520 network switch allows a device connected to the COMMON port to be shared between two devices, one connected to Port A and the other to Port B. For local control, a front panel button changes the switch position. Switch position and power status are displayed on the front panel LEDs.
