Page 6: Installation
Installation Caution: Wear a grounding strap or maintain a physical contact with equipment ground when setting the DIP switch. Failure to do so may result in failure of the media converter due to electrostatic discharge (ESD). Follow the normal procedures for installing this line card as described in the FRM220 Chassis Quick Start Guide. -
Page 7: Rs-485/422 Termination
RS-485/422 Termination Termination is used to match impedance of a node to the impedance of the transmission line being used. When impedances are mismatched, the transmitted signal is not completely absorbed by the load and a portion is reflected back into the transmission line. This reflection may cause errors in the data. -
