Output Modules
AMI 10-Output Module
Set these three switches for your application. Remember the settings apply to all 10
outputs of the AMI Output module, which means that the same length and type of
cable must be used on all outputs for the pulse shapes to be correct. If the cable
length is not known, change the switches while monitoring the wave shape until a
suitable wave shape is obtained. This may also be a useful method for setting the
switches when different types of cables are used, see
