Connecting the UT-300R2 to the Ethernet LAN
The UT-300R2 may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the UT-300R2 to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ- 45 port on the UT-300R2 is a crossed port (MDI-X). Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the UT-300R2 directly to a PC or server use a normal straight-through cable. You should use a crossed cable when connecting the UT- 300R2 to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to UT-300R2 connection. Be sure that the cable connecting the LAN to the UT-300R2 does not exceed 100 meters.
