EVK Hardware Connections and Initial Power-up
To set up the EVK hardware before using the software, complete the following procedure:
1.
Refer to Figure 2, Figure 3, and Table 1 to determine the correct jumper settings for the ZMOD4510 Communication Board depending on
whether an external supply or the internal voltage supply on the board is used.
If the internal voltage supply is used, ensure that the jumper is across the pins labeled “int” on the K2 connector.
If using an external supply, ensure that the jumper is across the pins labeled “ext” on the K2 connector. In this case, without
connecting the external supply to the Communication Board, verify that the external voltage supply setting does not exceed the
voltage supply specifications (i.e., a minimum of 1.7V and a maximum of 3.6V) as per the ZMOD4510 Datasheet. With the external
supply off, connect the external voltage to the 2-pin “+ - V ext” header adjacent to the K2 jumper with the orientation indicated in
Figure 3. Note: If this option is used, adjustments of the external voltage are not possible on either the Communication Board or the
Sensor Board for adjusting an external voltage supply.
2.
Install the ZMOD4510 Sensor Board on the 14-pin connector on the Communication Board, taking care to ensure the proper orientation
of the Sensor Board as shown on page 1.
3.
Insert the micro-USB cable into the X1 connector on the Communication Board and connect it to a free USB port on the user’s computer.
If the external voltage supply has been selected, turn on the external supply and verify that the D3 LED adjacent to the potentiometer is
on (see Figure 2). Note: The intensity of the green D3 LED is proportional to the supply voltage.
4.
Activate the software as described in “Software Installation and Setup”.
5.
If the internal voltage is used, the Gas Sensor Evaluation Software activates the internal voltage after the sensor has been started. Use
the metal potentiometer to the left of the K2 connector to adjust the VDD supply voltage in the typical range from 1.7V to 3.6V as
measured across the V_TGT and GND pins available on the K3 connector as shown in Figure 3. Its initial adjustment on delivery
provides a voltage of VDD ≈ 2.0V. Once a measurement has been started by the software, the green D3 LED adjacent to K2 will light
with an intensity proportional to the voltage supply that was set using the potentiometer.
6.
Verify that the red D1 LED is on, which indicates that the kit is properly connected and powered (see Figure 2).
The Communication Board provides the additional K3 and Modul1 connectors for the following optional uses as described in Table 1. To make
use of any of these options, contact IDT for further instructions (see contact information on last page).
Extra measurement options (e.g., current consumption to determine the power requirements of the ZMOD4510)
Connections for additional sensors (e.g., IDT humidity sensor HS3001)
