After pressing

iCal is connecting with PC. When the software can not find iCal,
there will be a message -“No ComPort”. At this moment, please
check if the USB-RS232 cable is plugged in the PC and if the
installer program is activated (please check the Device Manage r of
your system).

When the communication between PC (software) and iCal
(hardware) is successful, all the functions of tool bar will be
available. But if the communication suddenly stops, some
functions of the tool bar will not be available.

users switch iCal to SETUP function.) (Under Hz function, please
try not to enter SETUP function to prevent from errors.)

When the data recorded in iCal is of the same function, they will be
automatically sent into View . But when the data recorded in iCal is
of different functions, they will be put in a list in which users can
choose the data they want to download. They will not be sent into
View, but they can be exported to EXCEL (.csv or .txt).
When SAMPLE is set up as “0”, there will be a sample list in which
users can choose the data they want to download.

1. Communication

To get data from iCal (hardware), first users have to m ake su re the
PC (software) has already connected with iCal. There will be a
warning message – “Error Code 8021 !!” if the communication
stops. At this moment please press this Communication button
again. If the reconnecting still doesn’t work, then please restart
the software and the iCal.
