Data logging facilities are a standard in all
“C” series controllers, and with the Data Log
interval set to 30 mins - over 4 weeks of data
logged on a 24/7 basis, can be stored before it

on page 15.
Down loading the Data Log
The data in the data log can be retrieved in a
numbers of ways namely -
1. The data log can be down loaded locally to a
laptop using the
Free
Hyper Terminal program
available in Microsoft Windows program,
via a Serial cable attached to a laptop and
to the DB9 connector fitted internally in the
controller.
2. If a GSM modem and a SIM data card have
been fitted, the data log can be retrieved
remotely by again using Hyper Terminal.
Both of these methods retrieve the data log in text
format which will need further importation into an
Excel spreadsheet for trending and graphing for
reporting means.
3. Using AquaGuard 2 (30 day trial version) or
AquaGuard 2 + Activation Key, allow for the
data to be download into a database and with
direct importation into an Excel spreadsheet
- CWT_Graphs.xlt template to automate the
graphing, summary, and trending charts, and
speed up reporting. Use of a serial cable
and a laptop allows for local download as in
No. 1 above.
4. Where a GSM modem with a SIM data card
has been fitted - full remote control is available
using AquaGuard 2 software as in 3 above,
plus alarms to 3 phones, and remote start up
of disinfection, or changes to set points - all
from the PC or laptop in your office or car.
