On the back of my Silver Series HMI, there is a bank of DIP-switches. What are they for?
They are for servicing the Silver Series, and are not used in normal operation. Dip switch #1, when placed in the ON position, puts the unit in touch-screen calibration mode. Dip switch #2, when placed in the ON position and the unit is reset, will place the unit in forced communication mode. The unit will display 11 lines of text describing some internal configuration information and it will open the communication port and wait for a command from the host PC to initiate a download or upload. Be sure to flip all dipswitches back to the OFF position (down) for continued normal operation.
