Signal Output Module. Please refer to the Signal Output Module Manual.
Logging Data via the Hach Serial Input/Output Module

1. Press the
MENU key then the DOWN ARROW key until SETUP is displayed.
2. Press
ENTER.
3. Press the
DOWN ARROW key until DIAG OUTPUT is displayed.
Press
ENTER.
4. Use the up or
DOWN ARROW key to toggle the selection between ON and
OFF then press ENTER to select the displayed option. Press the EXIT key
to return to the measurement display.
The format of the data is illustrated below, where
n is the SIO
channel number for the CL17. (The channel number (1–8) is assigned
based on the order in which devices were added to the network.) Please
refer to the AquaTrend Interface Manual for information on determining the
channel number.
