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.

ION Module	Setup Registers	Available Settings	Default	Description
	Port	D1 to D4 or NOT USED	NOT USED	Specifies the output hardware channel
	Pulse Width	numeric	0.05	Pulse Width, in seconds
Calibration Pulser
	Kt	0.01 to 1 x 109	1.8 Wh	Specifies Watts per pulse
Module
	Output Mode	Pulse, KYZ	Pulse	Sets the type of output
	Int Mode	Forward, Reverse, Absolute, Net	Forward	Specifies the integration
	Port	As above	NOT USED	See above
Digital	Pulse Width	numeric	0	Pulse Width, in seconds
				(set to 0 for continuous pulse)
Output
	Polarity	Fixed at NON-INVERTING	NON-Inverting	Specifies non-inverted pulse
Module
	EvLog Mode	LOG ON or LOG OFF	LOG OFF	Specifies to store state changes in the
				Event Log
	Port	As above	NOT USED	See above
Pulser Module	PulseWidth	numeric	1	Pulse width, in seconds
	OutputMode	PULSE or KYZ	PULSE	Specifies full pulse or KYZ
	Polarity	Fixed at NON-INVERTING	NON-Inverting	Specifies non-inverted pulse

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.
