User's Manual

Rev. 2.2

The TC2200/2201 is equipped with multiple DIP switches for application setup and Panel LEDs to indicate
the status of electrical and optical signals. These features can ease installation and facilitate troubleshooting.
The following diagram depicts the board locations of several key components.
