| Jun 3, 2011 — Electro Standards Laboratories (ESL), Cranston, RI, has just announced its new PathWay® Model 7339 CAT5e 10/100/1000BASE-T Full/Half Duplex RJ45 A/B Automatic Fallback Switch with 10/100 Base-T LAN Telnet Access and GUI. The Model 7339 shares a single port interface device connected to the COMMON port among two other devices connected to the A and B ports. When in automatic fallback mode the unit monitors data activity on ports A and B. If activity is lost on A, the unit checks for data on Port B and in the presence of data, switches to position B. The Model 7339 data switch maintains its connection to port B until data activity is detected on port A, at which time the unit will automatically return to the A position. If no data is present on either port A or on port B, the unit will stay in the A position and continue to monitor for data. The user can override automatic fallback operation from the front panel or GUI interface and operate as an A/B switch. The switch ports are transparent to all data. All pins of the RJ45 interface are switched. All switched signals are passed via latching copper contact relays that maintain their position and continuity in the event of a power loss. Front panel LED’s display switch position, the switch mode (automatic fallback or manual) and power status.
