100BaseTX Fault Tolerant Transceiver
EFTT1003 with its fault tolerant function has been engineered for use in applications where connectivity integrity is crucial. This makes this unit ideal for medical, banking, industrial control, telecommunications, nuclear installations, security, law enforcement and military applications where network signal integrity is essential.
Features & Benefits
- Ensures connection even if a segment is damaged or sabotaged
- User selectable configuration, EFTT1003 to EFTT1003 or EFTT1003 to Hub
- Intelligent unit detects both loss of link pulse and loss of data
- User selectable Hunt or No Hunt
- User selectable half duplex/full duplex
- Two power supply jacks for redundant power supply
- Cross over switch on all three RJ45 connectors
- Compact rugged steel enclosure
- Designed & manufactured in the USA
EFTT1003 Fault Tolerant Transceiver (FTT) has an RJ45 to connect to the network device and two RJ45s for user selectable primary and secondary cable segments. The FTT hunts between these two segments to ensure that data can be transmitted at all times because the user has now added a fault tolerant redundant path. These two segments can be connected to a second EFTT1003 or to two ports of a standard 100BaseTX Hub, 10/100TX Hub or Switch. The added insurance of dual power supply inputs makes the EFTT1003 the first choice of MIS professionals with critical applications.
The user selectable parameter options, half or full duplex, segment A or B priority, hunt or no hunt & transceiver to transceiver or transceiver to hub. These make this unit exceptionally flexible and ideal for many different applications.
Power supplies are available for ether 110 VAC or 230 VAC.
Monitoring of the unit is simple with a complement of 10 LEDs that display LK (link) and REC (receive) on each RJ45, ENBL (enable) on segments A & B, global COL (collision) and PWR (power).
Each RJ45 connector has its own crossover switch allowing installation with standard twisted pair cables and eliminating the need for bothersome cross over cables.
