Black Box SW1046A
Remotely Controlled Layer 1 A/B Switch – DB9, 1 x 2
The Black Box SW1046A Remotely Controlled Layer 1 A/B Switch is designed for quick, reliable switching between two RS-232 devices. Supporting both manual and remote control, it ensures uninterrupted connectivity in industrial, IT, and test environments. Its non-latching relay design automatically defaults to port A when power is lost for added operational safety.
Features :
This DB9 serial A/B switch enables selection between two devices (Port A or Port B) connected to a common port (Port C) without re-cabling. Control is available via front panel pushbuttons, an RS-232 console port, or a 6-position terminal strip for integration into automated setups.
Advanced Options :
LED status indicators provide clear visual feedback of the active port and system state. Built with robust relay switching for signal integrity, the unit’s durable metal, desktop form factor fits neatly into workstations, labs, and control rooms for long-term, professional use.
