DB9 A-B Switch Latching Remote Control Dry Contact
The Black Box SW1047A DB9 A/B Switch has a 6 position terminal strip on the rear of the unit that provides remote control capability and accepts external dry contact closures as inputs for remote A/B switching. Switch ports are transparent to data rates, formats, and protocols and can handle speeds up to 10 Mbps. Manual control of the switch port connection state is supported through pushbutton switches on the front of the unit. The connection state will be maintained if power fails or is removed.
