INTERFACING
Serial Interface
The Model 6300 has a
7 data bits odd parity 1 stop bit
The 25 way D connector allows a standard
A printout is initiated by pressing the PRINT key. If the sample munber 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 6300 via the serial interface (using Windows Terminal or Jensoft, 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 6300 operating mode. For example: | 100.0 | 540 | ||
ASCII A<CR> | Outputs absorbance and wavelength separated by an ASCII TAB character, | ||||
| regardless of the 6300 operating mode. For example: | 0.001 | 540 | ||
ASCII C<CR> | Outputs concentration and wavelength separated by an ASCII TAB character, | ||||
| regardless of the 6300 operating mode. For example: | 123.4 | 540 | ||
ASCII V<CR> | Outputs a voltage proportional to the monochromatic light level passing | ||||
| through 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 calibrated. The shutter must be open for normal measurements.
ASCII Gnnn<CR> Commands the 6300 to go to the wavelength nnm. For example: G540<CR> will set the wavelength to 540nm.
