Description
The ZMID520x Evaluation Kit enables evaluation of the IDT
ZMID520x Family of Inductive Position Sensor ICs via IDT’s
ZMID520x Application Modules (available separately). It can be used for the sensor calibration for the following ICs:
ZMID5201: analog interface ZMID5202: PWM interface ZMID5203: SENT interface
The main purpose of the ZMID520x Evaluation Kit is communica­tion between the user’s computer and the ZMID520x. The user’s computer sends commands and data via its USB port to the ZMID Communication Board (ZMID-COMBOARD).
The microcontroller on the ZMID-COMBOARD interprets these commands and relays them to the ZMID520x located on the ZMID520x Application Module using the one-wire interface (OWI) communication interface.
The microcontroller also forwards data bytes from the ZMID520x back to the computer via the USB connection. These bytes can be sensor readings, ZMID520x internal registers values, or ZMID520x EEPROM contents.
The ZMID520x EVKIT Application Software is a graphical user interface (GUI) that is provided online for the kit. It supports all ZMID520x configurations and enables the user to understand the functionality of the ZMID520x as well as perform measurements.
Features
USB “plug and play” – no driver installation needed Small ZMID-COMBOARD: 4cm 7.3 cm
One-wire communication interface (OWI) enables quick and
easy configuration and calibration of the ZMID520x using the user’s computer
PWM, analog, or SENT reading of the output depending on
product code
The modular design allows easy swapping in different
ZMID520x Application Modules (available separately) for evaluation using the same ZMID-COMBOARD and ZMID520x EVKIT Application Software
The kit software is available for download from the IDT
product page for the ZMID-COMBOARD:

1.3.2 Connecting the Kit
Important Equipment Warning: Ensure the correct connection of all cables. Supplying the board using the wrong
polarity could result in damage to the board and/or the equipment.
1. Ensure that the ZMID-COMBOARD is not connected to the computer.
2. Assemble the ZMID520x Application Module with the target holder as described in the user manual for the specific application module.
3. Connect the ZMID520x Application Module via the flat cable to the ZMID-COMBOARD as shown in the example for the ZMID520x
Arc Application Module in Figure 2. See Figure 1 for the connections for the ZMID520x Linear Application Module and ZMID520x Rotary Application Module.
4. Connect the ZMID-COMBOARD to the computer using the micro-USB cable provided in the ZMID-COMBOARD. Power is provided
from the computer via the USB connection. No external power source is required.
5. The indicator LED2 on the ZMID-COMBOARD will light (see Figure 3) if conditions are normal. This indicates that the board is ready
to communicate with the ZMID520x EVKIT Application Software. The D1 LED on the ZMID520x Application Module (see Figure 4, Figure 5, or Figure 6) also lights when the board is powered on.

2.2 Getting Started
The following steps describe how to establish a connection to the ZMID520x Application Module and perform measurements. The combination of a ZMID-COMBOARD and its connected ZMID520x Application Module is referred to as the “device” in the GUI.
2.2.1 Connecting to a Device
1. Ensure that the ZMID520x Application Module is properly connected to the ZMID-COMBOARD. See section 1.3.2.
2. Connect the ZMID-COMBOARD to the user’s computer using the micro-USB cable provided in the kit.
3. Start the GUI application. See Figure 8 for the start-up screen.
4. The device will appear in the “Active Devices” section. If there are no other devices on the list, it will be automatically selected;
otherwise select it by clicking on it.
5. If the device shows as unknown, manually identify the device first. For a description of how to manually identify a device, refer to
section 2.6.
6. Click on the “Connect” button to initialize the connection.
7. After a successful connection, the GUI will display the contents of the main window area.
8. Two sensor boards can also be connected to the ZMID-COMBOARD at the same time; see Figure 10 for an example. Data are
displayed according to the selection made through the drop down menu on the top left side (Module 1 or Module 2). When connecting to two modules at the same time, both ZMID520x ICs on the modules must have the same output option (e.g., 2 x ZMID5201).

2.2.2 Reading Measurements
1. After connecting to a device, select the “MAIN” tab from the navigation menu. Two sub-tabs “OUTPUT” and “INTERNAL VALUES”
are displayed. For the ZMID5203, the “SENT” sub-tab is also displayed and provides a SENT interface decoder. The “OUTPUT” tab displays the reading at the ZMID520x output pin SOUT.
2. The readings can be displayed as scaled values in percent or as raw (decimal/hexadecimal) values. Use the “Component 1” radio
buttons (“%” or “Raw”) to select the desired method for presenting the values. If there are two devices, repeat the selection for the second device using the “Component 2” radio buttons.
The “OUTPUT” tab readings in percent represent
a. Analog values for the ZMID5201 – Percent of VDD b. PWM values for the ZMID5202 – Duty cycle of the signal c. SENT values for the ZMID5203 – Percent of the maximum position SENT value (4095)
The “OUTPUT” tab readings in raw data represent
a. Analog values for the ZMID5201 –12-bit value from the ZMID COMBOARD’s ADC with VDD for reference voltage b. PWM values for the ZMID5202 –12-bit value from the duty cycle calculation c. SENT values for the ZMID5203 – 12-bit position value decoded from the SENT stream
3. Clicking the “Start” button will activate the measurements and change this button to the “Stop” button. The GUI disables some of its
buttons and options while the measurement is active. Clicking the “Stop” button will deactivate the measurement and reactivate all options and buttons again.
4. At the bottom of each measurement tab, the “Enable Create Log” check box can be checked to log the measured values into a *.csv
file. The filename and its location are specified with the “Select File” entry field.
The “OUTPUT” tab displays the physical values by using either the ADC or digital inputs of the ZMID-COMBOARD. Figure 11 shows an example of SENT interface readings. For the PWM or analog interface, the values are captured using an analog-to-digital conversion by the microcontroller located on the ZMID-COMBOARD. Hence, the accuracy of the measured values is limited due to the setup. The ZMID Evaluation Kit is a configuration tool – it is not intended to act as a measurement device.
