Auto-Negotiation (selectable)
The Auto-Negotiation feature automatically configures the bridging media converter to achieve the best possible mode of operation over a link. The bridging media converter broadcasts its speed (10 Mbps or 100 Mbps) and duplex capabilities (full or half) to the other devices and negotiates the best mode of operation. Auto-Negotiation allows quick and easy installation because the optimal link is established automatically—no user intervention required.
In a scenario where the media converter is linked to a non-negotiating device, the user may want to disable Auto-Negotiation. In this instance, the mode of operation will drop to the least common denominator between the two devices (e.g., 10 Mbps, half-duplex).Disabling this feature gives the user the ability to force the connection to the desired speed and duplex mode.
Data Transfer rate (selectable)
10Base-T data transfer rate: 10 Mbps baseband Ethernet.
100Base-TX data transfer rate: 100 Mbps baseband Ethernet.
Full-Duplex network (selectable)
In a full-duplex network, maximum cable lengths are determined by the type of cables used. The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex network (selectable) (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the round trip delay limitations of each fast Ethernet collision domain. (A collision domain is the longest path between any two terminal devices, e.g., terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating the round-trip delay in bit times (BT) of a particular collision domain. If the result is less than or equal to 512 BT, the path is good.
AutoCross™
When the AutoCross feature is activated, it allows either straight-through MDI or crossover MDI-X cables to be used when connecting to 10Base-T or 100Base-TX devices. AutoCross determines the characteristics of the connection and automatically configures the unit to link up, regardless if the cable configuration is MDI or MDI-X. This feature is ON permanently.

Redundancy (selectable)
With redundancy enable and the primary port fails, the converter automatically switches data transfer responsibilities to the backup port without disrupting network traffic. After the primary port's failure is resolved, the converter automatically switches data transfer responsibilities back to the primary port.
Parallel detection
Parallel detection is the method used to link when an auto negotiating port detects a link partner that is in forced mode and therefore cannot participate in the auto negotiating process. Parallel Detection does not provide the ability to detect half versus full duplex mode
Per the IEEE method, an auto negotiating port that detects a forced link partner should drop to the detected speed (10Mbs or 100Mbs) and default to half duplex
The SBFTF-130 allows bypassing the IEEE method by setting the parallel detection default mode to half or full duplex via DIP switch 3 or through the duplex setting via WEB and Focal Point interfaces.
