5.2 Connect ToxiRAE to PC
The basic kit of the ToxiRAE is supplied with a serial
interface cable. Connect the DB-9 connector side of the
cable to the serial port of the PC, and connect another side
of the cable to the ToxiRAE monitor.
Turn on the power to the ToxiRAE monitor. Press the
[MODE]
key several times until the LCD shows
“Communicate with PC?” Press the
[Y/+]
key and the
display shows “Pause Monitor, OK?” Press
[Y/+]
key to
confirm and the display shows “Comm...” to indicate that
the ToxiRAE monitor is ready and waiting for
communication with PC. During the communication
session, the PC will directly control the ToxiRAE monitor
through the serial link. There is no need for users to press
any key on the ToxiRAE monitor during the
communication session.
If no data transfer has occurred within two minutes, the
ToxiRAE monitor will return to instantaneous reading
display.
Note: Do not connect to the parallel port of the PC by
mistake. The parallel port is usually a 25 pin
female D
connector
on the back of the PC, the serial port is usually
a 25 or 9 pin
male D connector
. If the serial port on the
PC is a 25-pin connector, the user needs to use a 25 pin to
9-pin adapter in order to accept the serial cable.
