EMI/RFI Protection
The MED100A is our Industrial Serial to Multi-mode Fiber
Optic Converter. Designed for industry, it extends serial data
range up to 2.5 miles and provides the most versatile
connection possible between any asynchronous full or half-
duplex serial equipment. In addition to direct point-to-point
connectivity, it is capable operating in a multi-drop mode. This
allows one serial device to communicate with up to 31 others
around a fiber optic ring. Since it supports mixed serial
standards, you can replace other converters and isolators and
add the EMI/RFI immunity inherent to fiber optic
communications.
In RS-232 mode, the MED100A supports transmit and
receive data. Handshaking signals are not passed through.
An Automatic Send Data Control circuit controls the RS-
422/485 driver chip, eliminating the requirement for special
software.
Easy to install and configure, it has an 8 position DIP
Switch to set up the RS-422/485 parameters and terminal
blocks to connect serial signals and power.
