4. The electrical section is capable of interfacing with any 10BaseT or 100BaseT RJ 45 twisted pair port If the ethernet port supports auto negotiation the DL221 A can be set to auto negotiate for optimum performance If the ethernet port does not support auto negotiation or if a fixed data rate and or fixed half or full duplex configuration is desired the Series DL221 DL221A transceivers can be forced into 10BaseT or 100BaseT mode and forced into half or full duplex mode In addition a crossover switch is pro vided which allows the Series DL221 DL221A transceivers to directly connect to either a standard or a crossover ethernet port The optical section is a 100BaseFX connection at all times The DL221 family of transceivers supports bi directional transmission over two single mode fibers The DL221A family of transceivers supports bi directional transmission over a single mode fiber In both cases Radiant s technology allows for extended transmission distances beyond the ethernet standard Problem Indication _ Corrective Action Improper network traffic Runt and late On the setup mode switches collision move S6 to the DOWN position and move it back to the UP position after one second Check the channel configuration Check that both ends of the fiber optic link are set to the same mode Half Duplex or Full Duplex Check that both sides of the UTP connection are in the same mode 10 Mbps Half d
