BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide 3.4 Calculating Overall Cable Segment Distance Important Note: Special consideration must be given to maximum cable segment lengths on each side of a 10 Mbps Economy Media Converter. It is recommended that IEEE 802.3 specifications for overall maximum segment distances be adhered to in order to maintain optimum network performance. (See also Technical Specs, Maximum Standard Ethernet Segment Distances, Section 1.1 of this manual.
BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide Media Distance Formula for 10 Mbps Economy Media Converters: X% + Y% < 100% Where X = The segment distance on one side of the Media Converter divided by the Standard Maximum Media Distance for that media type, x 100%.
BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide A Distance Calculation Example: Connectivity between ThinNet and TP Ethernet Media. In the figure shown above, the length of Segment X is 72m (216 ft). This is 39% of the maximum allowable distance for 10BASE2 media (185 m) [72/185 x 100% = 39%]. The length of Segment Y is 55m (165 ft). This is 55% of the maximum allowable distance for UTP 10BASE-T media (100 m) [55/100 x 100% = 55%].
BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide 3.5 Connecting Ethernet Media It is recommended that both of the media (TP and BNC) be connected with power off so that both ports are connected when power is applied to the logic in the electronics. If power is on, connect the Twisted Pair media before the BNC media. If BNC is connected before TP with power on, it can create a Jabber condition, in which case the JAB LED will come on and no packets will be processed. See Sections 4.
BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide 1. Using standard 10BASE-T media, insert either end of the cable with an RJ-45 plug into the RJ-45 connector of the Black Box Media Converter. 2. Connect the other end of the cable to the corresponding device. Use the LINK LED to ensure proper connectivity by noting that the LED will be illuminated when the units are powered and proper connections established.
BLACK BOX® 10Mb Economy BNC Media Converters Installation & User Guide 3.5.2 Connecting ThinNet (10BASE2) Note: connect TP media before connecting BNC media if power is on in the Media Converter unit. See Section 3.5 Connecting Media above. Connect the ThinNet coax cable to the BNC connector on the Media Converter in the same manner as is done for any standard BNC connection. Be sure that the BNC segment is properly terminated using a standard “T” connector.
