3-2) Switch settings for UART interface

Set switches SW2, SW3, SW4 (1 to 4) as follows:
SW2, SW3:
SW4-1, SW4-2, SW4-3, SW4-4: Set to OFF position
LED: TXD
LED: RXD
Caution‼ Do not change the preset positions of SW2, SW3, and SW4. Changing switch
positions may cause damage to the CDM7162 sensor.
3-3) Attaching CDM7162
The included CDM7162 sensor module is attached to the EM7162 evaluation module at the factory.
When replacing the CDM7162 or removing and remounting it, match the pin # of connectors CN1
and CN2 on EM7162 with the corresponding pin # of the CDM7162 (Figure 4).
Caution‼ Before mounting or removing CDM7162, be sure to turn off the power switch (SW1)
by setting it to the lower position as shown in Fig. 4.
Note) The standard CDM7162 CO
If you purchase additional CDM7162 sensor modules, solder commercially available pin
terminals to the CDM7162 and mount onto the evaluation module.
