Interface and output
The device is equipped with a 9-pin SUB-D connector on the rear side of the
device.
Serial interface RS 232 C
The serial assignment of the socket can be used to control the device exter-
nally by means of a PC and a suitable application program, e.g. labworld-
soft
® , from Version 5.0 on.
Configuration of the serial interface RS 232 C
• The function of the interface line between the laboratory
device and the automation system is a selection of the
signals specified in EIA Standard RS 232 C, corresponding
to DIN 66020 Part 1. For the assignment of the signals,
please refer to the illustration.
• Standard RS 232 C applies to the elctronic proerties of
the interfaces and the assignment of signal states inac-
cordance with DIN 66259 Part1.
• Transmission procedure: Asynchronous character transmission in start-stop mode
• Type of transmission: full duplex
• Character format: Character creation according to the data format in DIN
66022 for start-stop mode. 1start bit; 7 character bits; 1parity bit (even); 1 stopbit.
• Transmission speed: 9600 Bit/s
• Data flow conrol: no
Instruction Syntax
Here applies the following:
• The instructions are generally sent from the processor (master) to the
laboratory instrument (slave).
•The laboratory instrument exclusively sends on demand of the processor.
Even error codes cannot be spontaneously communicated from the labora-
tory instrument to the processor (automatic system).
• Instructions and parameters as well as subsequent parameters are separat-
ed by at least one blank. (Code: hex 0x20)
• Each individual instruction including parameters and data as well as each
reply are terminated with CR LF (Code: hex 0x0D and 0x0A) and have a
maximum lenght of 80 characters.
• The decimal separator in a floating point number is the point (Code: hex
0x2E).
