SECTION 6
– CONNECTING TO A PC
Connect the interface cable to the RS232 serial port on the rear of the instrument and connect to the
serial port on the rear of the PC. Turn the PC on and load the PC software by inserting the PC
software disc into the CD drive. If the PC software does not auto run open My Computer and double
click on the 63-Zero software icon. Follow the instructions to install the PC software to the required
location. Once the software is installed, turn the mains power on to the instrument.
The PC software is pre-configured to run using the following settings:
1200 baud
7 data bits
Odd parity
1 stop bit
The 25 way D connector allows a standard one-to-one interconnection lead to be used, as supplied
with the 40 column printer/interface cable kit.
A printout is initiated by pressing the PRINT key. If the sample number is unity, then the printout will
include a header block. The sample number is incremented every time the PRINT key is pressed.
The following commands can also be sent to the 6305 via the serial interface (using Windows
HyperTerminal, for example):
ASCII D or d Same as pressing the PRINT key
ASCII T<CR> Outputs transmission and wavelength separated by an ASCII TAB character,
regardless of the instrument operating mode. For example: 100.0 540
ASCII A<CR> Outputs absorbance and wavelength separated by an ASCII TAB character,
regardless of the instrument operating mode. For example: 0.001 540
ASCII C<CR> Outputs concentration and wavelength separated by an ASCII TAB character,
regardless of the instrument operating mode. For example: 123.4 540
ASCII V<CR> Outputs a voltage proportional to the monochromatic light level passing the
sample and wavelength separated by an ASCII TAB character. For
example: 1234.5 540
ASCII Z<CR> Calibrates a zero absorbance if the dark shutter is open (SO<CR>command),
or zero transmittance if the dark shutter is closed (SC<CR>command).
ASCII SC<CR> Closes the dark shutter which blocks monochromatic light entering the sample
chamber. This allows 0% transmittance to be calibrated.
ASCII SO<CR> Opens the dark shutter which allows monochromatic light to enter the sample
chamber. This allows 100% transmittance (zero absorbance) to be
