3-53.2.2 10BASE5 (AUI) ConnectionsAFP279010BASE5(AUI) connectionsConnect the transceiver cable to the 10BASE5 (AUI) connector (with D-SUB 15 pins retainer) on thefront panel of the unit. After you connect it, push down the retainer to fasten the cable.Transceiver and transceiver cable- The transceiver that you use must comply with IEEE802.3.- According to the ratings, transceiver cable can be up to 50 m in length but considering noise resistance,we recommend that you keep the cable under 5 m in length.- We recommend that you use a high-reliability connector type for the transceiver.External power supply terminal connections- Connect the external power supply terminal on the front panel of the unit to 12 V DC power supply topower the transceiver cable.- Note that the internal voltage drop is 1 V (max.).Earth- The F.G. pin of the external power supply terminal on the front of the unit is connected to the outermetallic shell of the 100BASE-TX/10BASE-T connector (RJ45), or the outer metallic shell of the10BASE5 (AUI) connector. These are also connected to the F.G. terminal of the power supply unitthrough the backplane.- In an environment with a high noise level, the F.G. terminal should be grounded at a groundingresistance of 100 Ω or less.
