The PathWay® Model 7954 Dual Channel RS-530 Mode-S, AB Switch with DB25 Interface, Remote Control and Solid-State Auto-Switching Functions allows the user two independent channels of A/B switch function.  The A/B function permits data on input MPS ports from either of two devices connected to ports MPSA-IN and MPSB-IN, to stream through to output ports MPSA-OUT and MPSB-OUT, respectively.  Only one position, A or B, may stream data at a time for each channel.  The PathWay® Model 7954 is configured to mount in a standard 19-inch equipment rack within 1U of rack space.

This 2-position data switch is controlled remotely from a device connected to its REMOTE port.  The Remote port has a custom interface DB25 connector located on the rear of the unit.  The various status, monitoring and control signals present on this port allow the switch to be managed by a device capable of interpreting these signals, and based on these signals, issue control commands to be executed by the switch.  The details of operation are discussed in the Operator's Manual.

The switch position status is displayed on the front panel LEDs.  There are no local control buttons on the unit.  All position control is managed via the Remote port.
