Jumper
Position Description
ENP VCC Connects the ENP pin of the ADN4680E to VCC, which enables global power-up for the device. The state of each
transceiver is determined by the DE1 to DE4 and RE1 to RE4 pins.
GND Connects the ENP pin of the ADN4680E to GND, which disables all transceivers on the device into a low power
mode.
FS1 VCC Connects the FS1 pin of the ADN4680E to VCC, which sets the RO1 receiver for Type 2 operation, supporting
fail-safe.
GND Connects the FS1 pin of the ADN4680E to GND, which sets the RO1 receiver for Type 1 operation for maximum
noise margin.
FS2 VCC Connects the FS2 pin of the ADN4680E to VCC, which sets the RO2 receiver for Type 2 operation, supporting
fail-safe.
GND Connects the FS2 pin of the ADN4680E to GND, which sets the RO2 receiver for Type 1 operation for maximum
noise margin.
FS3 VCC Connects the FS3 pin of the ADN4680E to VCC, which sets the RO3 receiver for Type 2 operation, supporting
fail-safe.
GND Connects the FS3 pin of the ADN4680E to GND, which sets the RO3 receiver for Type 1 operation for maximum
noise margin.
FS4 VCC Connects the FS4 pin of the ADN4680E to VCC, which sets the RO4 receiver for Type 2 operation, supporting
fail-safe.
GND Connects the FS4 pin of the ADN4680E to GND, which sets the RO4 receiver for Type 1 operation for maximum
noise margin.
RE1 VCC Connects the RE1 pin of the ADN4680E to VCC, which disables the RO1 receiver, placing it in a high impedance
state.
GND Connects the RE1 pin of the ADN4680E to GND, which enables the RO1 receiver if the ENP jumper is connected to
VCC.
Disconnected Disconnects the RE1 pin from VCC or GND, which allows the RE1 pin to be controlled from the RE1 connection on
the P3 screw terminal block.
RE2 VCC Connects the RE2 pin of the ADN4680E to VCC, which disables the RO2 receiver, placing it in a high impedance
state.
GND Connects the RE2 pin of the ADN4680E to GND, which enables the RO2 receiver if the ENP jumper is connected to
VCC.
Disconnected Disconnects the RE2 pin from VCC or GND, which allows the RE2 pin to be controlled from the RE2 connection on
the P3 screw terminal block.
RE3 VCC Connects the RE3 pin of the ADN4680E to VCC, which disables the RO3 receiver, placing it in a high impedance
state.
GND Connects the RE3 pin of the ADN4680E to GND, which enables the RO3 receiver if the ENP jumper is connected to
VCC.
Disconnected Disconnects the RE3 pin from VCC or GND, which allows the RE3 pin to be controlled from the RE3 connection on
the P5 screw terminal block.
RE4 VCC Connects the RE4 pin of the ADN4680E to VCC, which disables the RO4 receiver, placing it in a high impedance
state.
GND Connects the RE4 pin of the ADN4680E to GND, which enables the RO4 receiver if the ENP jumper is connected to
VCC.
Disconnected Disconnects the RE4 pin from VCC or GND, which allows the RE4 pin to be controlled from the RE4 connection on
the P5 screw terminal block.
DE1 VCC Connects the DE1 pin of the ADN4680E to VCC, which enables the A1 and B1 transmitter if the ENP jumper is
connected to VCC.
GND Connects the DE1 pin of the ADN4680E to GND, which disables the A1 and B1 transmitter, placing it in a high
impedance state.
