If your computer has an internal modem, make sure that the communication
port is not being used by it. When the communication port is being used as
the modem port, that port cannot be used. Either quit using the modem or
use another port.
A
If your computer has no serial port, use a Serial-USB conversion cable and
carry out communication via USB connection.
We recommend I.O DATA USB-RSAQ2 and ELECOM UC-SGT
Serial-USB conversion cables.
If you are using an NEC Lavie J Notebook Computer (NEC LJ-500),
please use I.O DATA USB-RSAQ2.
A
Sometimes communication will not work if a switch has been added to the
serial port (RS-232C) or an extension cable has been added to the
communication cable.
A
Check to see if some other communication software is in use.
A
If your desktop computer has two serial ports, try connecting the
communication cable to the other port and try communicating again.
Q2
I can't get the communication cable connected to the
computer. What should I do?
A
Please connect the communication cable provided with the Voltage Logger
into the serial port of your computer (D-SUB 9 pin male connector). If for
some reason you cannot connect directly, please use an appropriate adapter
(gender changer plug) as explained below.
Ȇ
If the connector on your computer is a D-SUB 9 pin male then there is
no need for an adapter.
Ȇ
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).
Ȇ
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).
Ȇ
Please use only straight conversion adapters.
