DATA TERMINATION REQUIREMENTS
Manchester Data Signals
The Manchester data input on the MRX-8423C is internally terminated with 120 ohms. It is
recommended to provide a 120 ohm termination at the copper device which is terminating the
MTX-8423C data output signal. If the MTX-8423C data output signal is daisy chained to more
than one device, only the last device in the chain should be terminated.
