Weidmuller converter is able to connect several serial devices to form a glass fiber ring. This simply involves connecting the TX port of one converter with the Rx port of a neighbouring converter. Ring mode can then be activated using the DIP switch on the device. A signal which is transmitted by a node is then forwarded in the ring until it is gets back to the sender, where it is blocked. In this way, glass fiber rings can be configured with an spread of up to 100 km. Weidmuller serial/fiber-optic converter can automatically detect the serial baud rate of connected devices. This ensures that signals can be forwarded by the media converter without any data loss even if the baud rate of a connected device changes.
