PRINTING OVERVIEW
A laptop computer can be connected to the Control
Center’s Microboard to print the following reports.
The screen from which each report can be generated is
listed below in parenthesis.
• Status ‑ System parameters (Printer, Home)
• Setpoints ‑ Programmed values of all setpoints
(Printer, Setpoints)
• Schedule ‑ Value of programmed daily schedule
(Printer, Schedule)
• Sales Order ‑ Information about SALES ORDER
Screen (Printer, Sales Order)
• History ‑ System parameters at the time of the last
normal stop, last fault while running and last 10
faults, whether running or not (Printer, History)
•
Cycling or Safety Shutdown Initiated Print ‑
Snapshot of all system parameters at instant of
shutdown. Automatically occurs if printer is con-
nected at time of shutdown.
• Trend ‑ Prints a snapshot of the existing TREND
Screen data or prints new data collected after the
TREND PRINT key is pressed.
A laptop computer can be permanently connected to the
Control Center or connected as required to generate a
report. If permanently connected, a DATA LOGGING
feature can produce a status report automatically, be-
ginning at an Operator selected start time and occur-
ring at an Operator selected interval thereafter. An SD
data card can log chiller parameters every 0.1 to 60
seconds (Default 1.0 seconds) and reviewed in Excel.
The following figures are examples of the different
print reports.

tween prints.
DOWNLOADING SYSTEM PRINTS TO A
LAPTOP
Downloading system histories to a file is another use-
ful method to capture system operating conditions. The
following instructions are used to establish communi-
cation between the OptiView Control Panel and a lap-
top computer running any terminal emulation program
such as HyperTerminal, TeraTerm or PuTTy.
1. Connect the laptop computer to the OptiView as
described below.
LAPTOP
(RS-232 SERIAL
PORT)
OPTIVIEW
(COM 1)
PIN DESC Connector Terminal
2 RX to J2 4 (TXD1)
4 DTR to J2 2 (DSR1)
5 GND to J2 8 GND
2. On OptiView Printer Screen, select “PC”. This
will allow faster data download than the printer
selections. On Setpoints - Setup - Comms screen,
ensure the printer settings match “h. Port settings”
