The UltraRAE monitor includes 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
MultiRAE PLUS monitor.
Turn on the power to the UltraRAE monitor. Press the
[MODE]
key several times until the LCD shows “PC comm?”
Press the
[Y/+]
key and the display shows “Monitor will Pause,
OK?” Press
[Y/+]
key to confirm and the display shows
“Ready...” to indicate that the UltraRAE monitor is ready for
communication with PC. During the communication session,
the PC will directly control the UltraRAE monitor through the
serial link. There is no need for users to press any key on the
MultiRAE PLUS monitor during the communication session.
If no data transfer has occurred within one minute, the
UltraRAE 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.
