Follow the steps The MAX14829 evaluation kit (EV kit) is a fully assembled below to verify board operation before exercising the full and tested circuit board that evaluates the MAX14829 features of the device: IO-Link device transceiver. 1) Verify that all the jumpers are in their default positions, The MAX14829 EV kit can be operated stand-alone with as shown in Table 1. pin-strapping or can be driven by a microcontroller using the Arduino-compatible interface. 2) Ensure that SW1 is set to position 1 (to the far left). 3) Connect the 24V DC power supply on the V (TP1 Features 24 or TP3) and GND (TP4 or TP19) connectors of the EV IO-Link-Compliant Device Transceiver kit board. IO Interface Terminals 4) Connect the oscilloscope to the C/Q test point (TP8). Proven PCB Layout 5) Turn on the power supply. Fully Assembled and Tested 6) Connect the multimeter to pin 1 on the J4 jumper. Pads for an Arduino Compatible Shield Verify that the voltage on the multimeter is 5V. 7) Connect the multimeter to pin 3 on the J4 jumper. Verify that the voltage on the multimeter is 3.3V. Quick Start 8) Set the function generator to generate a 0 to 3.3V Recommended Equipment square wave at 100kHz. MAX14829 EV kit 9) Connect the oscilloscope to the TX (TP19) and C/Q 24V, 500mA DC power supply (TP8) test points. Multimeter 10) Connect the function generator to the TX test point (TP19). Function generator 11) Enable the function generator. Oscilloscope 12) Verify that the C/Q output switches with the TX input. Ordering Information appears at end of data sheet.
