Item 4: 0 (Control Channel)

Each Digital Output is active when it is LOW and inactive when it is HIGH.

This is called “negative logic.”

Line items 1, 2, and 3 allow you to set the schedule at which a Digital Output will be set LOW. If

connected to a relay, it will control the action of the relay. The schedule is independent of the Sample

Interval definition:

Digital

Output Menu

Line Item No. Name Definition

1 Power-On Interval Defines how frequently the Digital Output will be

turned on.

2 Power-On Duration Defines how long the Digital Output will be on each

time it is turned on.

3 Start of First Power-On Defines when initial starting time of the cycle.

Similar to an offset.

For example, the Digital Output could be switched on for the first 5 minutes of every hour to turn on a bi-

directional radio, while the Sample Interval calls for a new measurement every 10 minutes. A Power-on

Interval and Power-on Duration of up to 168 hours (7 days) can be entered in the format hhh:mm:ss.

Power-on corresponds to the Digital Output set LOW; power-off to the Digital Output set HIGH.

Valid values for Line Item #4, the Digital Control Output, are 18 through 23, corresponding to the Digital

Outputs on the ZENO

. If you set Line Item #4 to 0 (or if you set Line Item #1, the

Power-on Interval to 000:00:00), then the Digital Control Output will be disabled (as the above example

of the Digital Control Menu shows).
