This section describes controller connections with a fiber-optic media converter. The media converter converts 10BaseT TP to 10Base-FL ST fiber cable without repeating the signals and is used in conjunction with the controller to allow an Ethernet link to a range of 2000 meters. The following table shows the media converter specifications.
The media converter mounts on a 2-wide carrier next to (or close to) the controller and connects to the controller with two standard 12 to 16 inch twisted pair cables with shielded connectors on both ends of the cable. The four fiber-optic cables connect transmit to receive between the Workstation’s media converter and the controller’s media converter as shown in the following figure. The dimensions for the fiber-optic media converter case are the same as the controller case. The connectors on the media converter extend one half inch above the case.
