6.1.2 Configure Serial Port 1 Mode
Serial port 1, of the HMI, is used to communicate with the control module (CM). This is a three wire,
RS232 serial link. In order for the link to operate properly, the serial port on the HMI must be set for
RS232. If the serial port is not set properly, the EZT-570i application will not start and will remain on
the splash screen. The “hour glass” will continue to turn and the “COM” LED on the HMI will flash as
it tries to communicate with the CM.
Figure 6-3 Write Error on Boot
To check the serial port settings, power down the EZT. Remove the SD card from the bottom of the
HMI and turn the power back on. Allow the HMI to boot up to the Windows desktop. Insert the SD
card back into the bottom of the HMI. Touch the small gray bar at the bottom of the screen to open
up the start menu. Press the “Start” button and select “CECP” from the “programs” menu.
