M4520 DB15 A/B Switch Features Local Pushbutton & Remote Contact Closure Controls

Sept. 9, 2010 - PRLog -- Electro Standards Laboratories, Cranston, RI, announces the PathWay® Model 4520 DB15 Interface A/B Switch. Each of the A, B, and COMMON ports are DB15 female. The Model 4520 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.

The Model 4520 network switch includes a DB9 Remote rear panel port. A simple dry contact closure across the specified pins of the remote port provides the change position command to the switch. Lockout pins on the Remote port, when shorted, lockout front panel control of the switch position.

This high-quality network switch is available to city, state, and federal government purchasers at a discounted price and favorable payment and shipping terms via GSA Schedule GS-35F-0286V.
