Interface And Output - IKA RC 2 GREEN basic Operating Instructions Manual

The device can be operated in "Remote" mode via the RS 232
port (5) or the USB port (6) connected to a PC and with the
laboratory software Labworldsoft
Note: Please observe the system requirements together
with the operating instructions and help section included
with the software�
USB interface:
The Universal Serial Bus (USB) is a serial bus for connecting
the device to the PC� Equipped with USB devices can be
connected to a PC during operation (hot plugging)� Con-
nected devices and their properties are automatically recog-
nized� The USB port can also be used to update firmware�
USB device driver:
First, download the latest driver for IKA devices with USB
port from:
http://www.ika.com/ika/lws/download/usb-driver.zip.
Install the driver by running the setup file� Then connect the
IKA device through the USB data cable to the PC�
The data communication is via a virtual COM port� Configu-
ration, command syntax and commands of the virtual COM
ports are as described in RS 232 interface�
Device software update:
For device software update, visit IKA website www.ika.
com and enter the "Service" menu� Download and run the
Firmware Update Tool�
Find and click the Firmware Update Tool in your PC after
installation� Register your E-mail and password�
Connect the device to your PC via the USB cable� Then, you
can update the device software according to instructions of
the Firmware Update Tool�
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recom-
mendations 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 communica-
tion between the device and the PC� With a suitable terminal or communications programme these commands can be
transmitted directly to the circulator equipment� The IKA software package, Labworldsoft
controlling circulating equipment and collecting data under MS Windows, and includes graphical entry features, for pump
motor speed ramps for example�

RS 232 interface:
Configuration:
- The functions of the interface connections between the
device and the automation system are chosen from the
signals specified in EIA standard RS 232 in accordance
with DIN 66 020 Part 1�
- For the electrical characteristics of the interface and the al-
location of signal status, standard RS 232 applies in accor-
dance with DIN 66 259 Part 1�
- Transmission procedure: asynchronous character transmis-
sion in start-stop mode�
- Type of transmission: full duplex�
- 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 device to the com-
puter 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 (Master)
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 CR LF (Code: hex 0x0d
hex 0x0A) and have a maximum length of 80 characters�
- The decimal separator in a number is a dot (Code: hex
0x2E)�
