  • Page 3: Chapter 1 - Overview

    Rev. 2.2 Description The TC2200R/S and TC2201R/S are multi-drop fiber optic modems that convert electrical signals to fiber optic signals (and vice-versa). At least one TC2200 (Master) unit and one TC2201 (Slave) unit are required to communicate with each other. The Master unit is connected to a Host computer (or controller), while the Slave unit can be connected to an RTU (Remote Terminal Unit), PLC (Programmable Logic Controller) or any poll-response type device.
