Q : : : : :
I can't get the communication cable connected to the computer. What should I do?
A：
Please connect the communication cable provided with the Thermo Recorder into the
serial port of your computer (D-SUB 9 pin male connector). If for some reason you
can not connect directly, please use an appropriate adapter (gender changer plug)
as explained below.
Examples of various serial ports:
《 》 《
D-SUB 9 pin male D-SUB 25 pin female
・ ・ ・ ・ ・ If the connector on your computer is a D-SUB 9-pin male then there is no need for
an adapter.
・ ・ ・ ・ ・ If the connector on your computer is a D-SUB 25 pin female then use an adapter
(D-SUB 25 pin male to a D-SUB 9 pin male)
・ ・ ・ ・ ・ If the connector on your computer is a Half pitch 14 pin female then use the adapter
(Half pitch 14 pin male to a D-SUB 9 pin male) or a combination (Half pitch 14 pin
male to D-SUB 25 pin male) and (D-SUB 25 pin female to a D-SUB 9 pin male).
Q : : : : :
I can't download settings and / or data from the Thermo Recorder to my computer.
What should I do?
A：
Check to make sure that the connection is proper. Communication will take place
only through the serial port (RS-232C) and will not work through the printer port or
any other.
A： Check to make sure that you can control the Thermo Recorder with the software.
A：
Make sure that the serial port has been selected correctly in the [Communication]
pull down menu in the software. Please check which port you are connected to
(COM1-COM4) and select appropriately.
A：
If you have access to another computer try to see if you can download using it.
A：
If you have a computer with energy saving function settings, make sure that the serial
port has not been turned off. Especially on NEC brand PC98 notebook computers the
default setting may be such.
A：
If your computer is a DOS/V type check to make sure that the serial port has not been
rendered unusable by the BIOS setting.
A：
If your computer is Windows 95/98 please make sure that the serial port setting has
not been made to render it unusable. With many all in one computers it serves as the
modem jack.

《 How to check 》
① In Windows 95/98 Open the [System] file in the [Control Panel] (Figure 1).
《Figure 1 Control Panel》
②Open the [Device Manager] file in the [System Properties] window and double click
on [Port (COM&LPT)] (Figure2) to open. Check to see if [Com Port (COM1)] and/or
[Com Port (COM2)] are displayed. If so they should be usable unless they have a [!]
or a [x] (Figure 3) mark on them, If such a mark exists, that port is unusable. If you
can not use a communication port please contact your computer's maker.
《Figure 2 [Device Manager]》
・To find out more details about the port in question you can double click on [！ ] to
open [Properties] and a window giving details about that port will appear.
A：
If your computer has an internal modem, make sure that the communication port is
not being used by it. In some cases even though no settings appear for the commu-
nication port, it can not be used. Check to see which port is being used by the
modem.
