Interfaces and outputs
USB interface
The Universal Serial Bus (USB) is a serial bus system for connec-
ting the KS 3000 to the PC. Devices with USB capabilities can be
connected and disconnected whilst in operation (hot-plugging);
connected devices and their properties are also detected automa-
tically.
The USB interface is used in conjunction with labworldsoft
® for
operation in “Remote” mode
Installation
Connect the KS 3000 to the PC using the USB data cable. The KS
3000 will then transmit information to the Windows operating
system to tell it which device drivers are required. Windows will
then either:
- Load the driver
- Install the driver automatically, if it is not already installed
- Prompt the user to perform a manual installation
- In this case, select the appropriate download from the IKA
Internet product page.
Configuration
The unit can be controlled from an external PC (using the dedica-
ted software labworldsoft) via the RS 232 C serial interface / USB
fitted to the unit.
To increase safety when controlling the shaking unit from
a PC, enable the watchdog function for monitoring the
continuous serial data flow (see section watchdog function)
• The functions of the inteface lines between laboratory instru-
ment and automation system are selected from the specfied
signals of the EIA-standard RS 232 C, corresponding with DIN
66020 Part 1. The allotment of the bushing can be taken from
illustration.
• For the electrical properties of the interface lines and for the
allotment of the signal status, standard RS 232 C, correspon-
ding with DIN 66259 Part 1 applies.
• Transmission method: Asynchronous signal transmissi-
on in start-stop-operation.
• Mode of transmission: Fully Duplex
• Character format: Character imaging acc. to data
format DIN 66022 for start –
stop operation. 1 start bit;
7 character bits; 1 parity bit-
[straight (even)]; 1 stop bit..
• Transmission speed: 9600 Bit/s
• Access method: Data communication from sha-
ker to computer is only possible
on demand of the computer.
Instruction syntax
Here applies thje following:
• The instructionsare 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 communi-
cated from the laboratory instrument to the processor (automa-
tic system)
• Instructions and parameters as well as subsequent parameters
are separated by at least o n e 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)
The above statements largely correspond with the recommenda-
tions of the NAMUR-Assocation (NAMUR-recommendations for
the design of electric plug connections for the analog and digital
signal transmission to labortory - MSR individual units. Rev. 1.1).
