Installation Guideline
Changing Baud rate and Checksum
Baud rate and checksum settings have several things in common:
• They should be the same for all modules and host computer.
• Their setting can only be changed by putting a module in the INIT*
state.
• Changed settings can only take effect after a module is rebooted
To alter baud rate or checksum settings you must perform the following
steps:
• Power on all components except the ADAM Module.
• Power the ADAM module on while shorting the INIT* and GND
terminals (See Figure 2-3).
• Wait at least 7 seconds to let self calibration and ranging take effect.
• Configure the checksum status and/or the baud rate.
• Switch the power to the ADAM Module OFF.
• Remove the grounding of the INIT* terminal and power the module on.
• Wait at least 7 seconds to let self calibration and ranging take effect.
• Check the settings (If the baud rate has changed, the settings on the host
computer should be changed accordingly).
