The evaluation board allows the input and 1.62 V to 5.5 V VIO logic supply output functions to be exercised without external components. IEC ESD protection on the RS-485 A, B, Y and Z bus pins Screw terminal blocks provide convenient connections for power 12 kV contact discharge and 12 kV air discharge and ground, digital input and output signals, and RS-485 signals. Screw terminal blocks for logic input/output and RS-485 signals The evaluation board is powered by a standard configurable Jumper-selectable enable or disable for RE and DE benchtop power supply within the 3.0 V to 5.5 V range. A flexible Test points for measuring all signals V IO logic supply allows communication with processors running on Resistors and footprints for termination and biasing networks voltages as low as 1.62 V. EVALUATION KIT CONTENTS The EVAL-ADM3068EEBZ evaluation board has a footprint for EVAL-ADM3068EEBZ evaluation board the ADM3068EBRZ full duplex, RS-485 transceiver in a 14-lead SOIC N package. EQUIPMENT NEEDED Oscilloscope For full details, see the ADM3068E data sheet, which must Signal generator be used in conjunction with this user guide and the EVAL- 3.0 V to 5.5 V supply ADM3068EEBZ evaluation board. 1.62 V to 5.5 V supply EVALUATION BOARD PHOTOGRAPH Figure 1.
