Digital Output 1 and Digital Output 2

Itron water modules are compatible with all sizes of Digital Output 1 and Digital Output 2 registers and CMAG/EMAG meters.

Cadillac meters are approved for use in the configurations described in Table 12 and Table 13.

Table 12 Itron Configurations: Cadillac Meter (Flow Units: Gal/Min and Gallons) for 60WP and 100WP/+

Size	Display 1	Display 2	R1	DO1 function	Count rate	Pulse mode	Pulse width
0.5” thru 6”	gal/min	Count F	5 m/s	PLS Out	10 gal	Auto	100 ms
8” thru 24”	gal/min	Count F	5 m/s	PLS Out	100 gal	Auto	100 ms
28” thru 36”	gal/min	Count F	5 m/s	PLS Out	1000 gal	Auto	100 ms

Table 13 Itron Configurations: Cadillac Meter (Flow Units: Ft3/Min and Ft3) for 60WP and 100WP/+

Size	Display 1	Display 2	R1	DO1 function	Count rate	Pulse mode	Pulse width
0.5” thru 20”	gal/min	Count F	5 m/s	PLS Out	10 Ft3	Auto	100 ms
24” thru 36”	gal/min	Count F	5 m/s	PLS Out	100 Ft3	Auto	100 ms

Additionally:

• R1, which is meter flow span setting, is determined by using approximately five m/s as maximum system design velocity.

• When Pulse Mode is set to Auto, the default for Pulse Width becomes 100 ms.

• Count Rate (Pulse scaling factor) can always be larger than what is listed for any given meter size. It cannot be smaller and must meet 100 ms pulse width.

• Pulser ERTs must be programmed to 100ms Pulse seven-digit driver.

The following list describes the water modules with which this register is compatible.
