Interface And Output - IKA IC control Instrucciones De Manejo

Factory Settings:
Select the "Factory settings" option by turning and
pressing the rotary/push knob. The system requests con-
firmation to restore the factory settings. Pressing the
"OK" button resets all the system settings to the origi-
nal standard values set at dispatch from the factory (see
"Menu structure").
The device can be connected to a PC and operated with the
laboratory software labworldsoft
(10), USB port (11) or USB port on the Wireless Controller
(WiCo).
Note: Please comply with the system requirements to-
gether with the operating instructions and help section
included with the software.
USB interface
The Universal Serial Bus (USB) is a serial bus for connect-
ing the device to the PC. Equipped with USB devices can
be connected to a PC during operation (hot plugging).
Connected devices and their properties are automatically
recognized. The USB interface can also be used to update
firmware.
USB device drivers
After the device is connected to the PC through the USB
cable, it tells the Windows operating system with which
device drivers are required.
Windows operating system will then either:
- load the driver
- install the driver if it is not already installed
- require manual installation, select:

The data communication is via a virtual COM port.
Configuration, command syntax and commands of the vir-
tual COM ports are as described in RS 232 interface.
RS 232 interface
Configuration
- The functions of the interface connections between the
stirrer machine and the automation system are chosen
from the signals specified in EIA standard RS 232 in ac-
cordance with DIN 66 020 Part 1.
- For the electrical characteristics of the interface and the
allocation of signal status, standard RS 232 applies in ac-
cordance with DIN 66 259 Part 1.
- Transmission procedure: asynchronous character trans-
mission in start-stop mode.
- Type of transmission: full duplex.

Information:
The "Information" option offers the user an overview
of the most important system settings of the device.
- Character format: character representation in accordance
with data format in DIN 66 022 for start-stop mode. 1
start bit; 7 character bits; 1 parity bit (even); 1 stop bit.
- Transmission speed: 9600 bit/s.
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer's request.
Command syntax and format
The following applies to the command set:
- Commands are generally sent from the computer (Mas-
ter) to the device (Slave).
- The device sends only at the computer's request. Even
fault indications cannot be sent spontaneously from the
device to the computer (automation system).
- Commands are transmitted in capital letters.
- Commands and parameters including successive parame-
ters are separated by at least one space (Code: hex 0x20).
- Each individual command (incl. parameters and data)
and each response are terminated with Blank CR Blank
LF (Code: hex 0x20 hex 0x0d hex 0x20 hex 0x0A) and
have a maximum length of 80 characters.
- The decimal separator in a number is a dot (Code: hex
0x2E).
The above details correspond as far as possible to the rec-
ommendations of the NAMUR working party (NAMUR rec-
ommendations for the design of electrical plug connections
for analogue and digital signal transmission on individual
items of laboratory control equipment, rev. 1.1).
The NAMUR commands and the additional specific IKA
co mmands serve only as low level commands for commu-
nication between the device and the PC. With a suitable
terminal or communications programme these commands
can be transmitted directly to the circulator equipment. The
