| | Feb 15, 2011 — Electro Standards Laboratories, Cranston, RI, announces the PathWay® Model 7248-ESL Dual-Channel RS530 A/B switch with Cutoff and Remote Control. Channel One allows sharing a single DB25(F) interface device connected to the Common port among two other DB25(M) devices connected to the A and B DB25 ports. Channel Two allows sharing a single DB25(M) interface device connected to the Common port among two other DB25(F) devices connected to the A and B DB25 ports.
Both channels allow the user to set the switches to the CUTOFF position, which stops any and all data throughput for the switch. The switch may be controlled locally via pushbuttons or remotely from the rear-panel DB9 Control port using either contact closures or an RS232 command interface.
The front panel LED displays indicate the respective switch position and unit power status. All ports for each switch are transparent to all data going through that switch. If power to the Model 7248-ESL is removed, both switches automatically move to the CUTOFF position. When it is restored, each switch will move to the programmed default position.
