IBM Visible Range Spectrophotometer 6300 - Manual (Page 16)

ASCII Fxxxx.x Sets the concentration factor to xxxx.x. For example: F1000 will set the
factor to 1000.
Note 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:
6300
IBM PC XT (25 way “D”)
TXD 2 2 TXD (From PC)
RXD 3 3 RXD (To PC)
RTS 4 4 RTS (From PC)
CTS 5 5 CTS (To PC)
DSR 6 6 DSR (To PC)
DCD 8 8 DCD (To PC)
DTR 20 20 DTR (From PC)
GND 7 7 GND
6300 IBM PC XT (9 way “D”)
TXD 2 3 TXD (From PC)
RXD 3 2 RXD (To PC)
RTS 4 7 RTS (From PC)
CTS 5 8 CTS (To PC)
DSR 6 6 DSR (To PC)
DCD 8 1 DCD (To PC)
DTR 20 4 DTR (From PC)

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
