IBM Visible Range Spectrophotometer 6300 - Manual (Page 16)

ASCII Fxxxx.x<CR> Sets the concentration factor to xxxx.x. For example: F1000<CR> will set the
factor to 1000.
Note <CR> is an ASCII carriage return character.
The last three commands provide an output which can readily be incorporated into most spreadsheet
software packages.
6.2 RS232 Output
The bi-directional RS232 interface is available on the rear panel 25 way D type connector.
The connections are as follows:
TXD 2
- INPUT TO 6300
RXD 3 - OUTPUT FROM 6300
RTS 4 - LINKED TO CTS
CTS 5 - LINKED TO RTS
DSR 6 - OUTPUT FROM 6300
DCD 8 - OUTPUT FRM 6300
DTR 20 - INPUT TO 6300 (must be active)
GND 7
Suggested interconnections are detailed below:

NOTE: The Interface Cable Kit (Order Code: 542 009) can be used to implement the
above interconnections.
Recorder Output
This is available via the 4mm rear panel sockets. The level is proportional to the displayed reading, de-
pending on the measurement mode:
Transmission 1mV per 0.1%T
Absorbance 1mV per 0.001ABS
Concentration 1mV per concentration unit
