Using the Onboard Digital Outputs
The four digital output ports are located on the rear of the meter. ION Digital
Output, Calibration Pulser, or Pulser modules control the function of the digital
output ports. These modules define the characteristics of outgoing signals and can
act as intermediaries between the hardware port and the other modules in the
meter. Digital Output ports can be used to control relays or send status signals.
You configure Digital Output, Calibration Pulser, and Pulser modules by
specifying to which hardware port they send signals. You are also responsible for
the settings that define the type of pulses the modules send. Once you have
configured the modules, they can be controlled by other ION modules that
provide trigger outputs.
The following table summarizes the settings for these modules.
NOTE
Remember that if the port you want to use does not appear in the
Port
setup register’s list, then that port
is in use by another module. You must edit the
Port
setup register of the module using the port, setting it
to NOT USED, if you want the port to be available to other modules.
