F Connecting Encoders
Warning
Never connect any signals while the Ranger unit is powered.
Never connect a powered I/O & Encoder Interface unit to a Ranger.
Never connect anything but TTL signal levels to the encoder inputs.
Failure to follow these rules may damage the Ranger unit.
The RS-422 inputs on the Ranger E and D have internal termination, which makes it
possible to connect an RS-422 encoder to the Ranger without requiring any external
termination.
With this termination it is possible to directly connect up to two Rangers to the same
encoder. If more than two Rangers are going to use the same encoder, the encoder and
Rangers should be connected to the Encoder terminal accessory. With this device it is
possible for up to eight Rangers to use the signals from the very same encoder.
