- 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 above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recommenda-
tions 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
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
circulating equipment and collecting data under MS Windows, and includes graphical entry features, for pump motor speed
ramps for example.

Commands Function
IN_PV_1 Read the external actual temperature
IN_PV_2 Read the internal actual temperature
IN_PV_3 Read the safety actual temperature
IN_PV_4 Read the pump actual speed
IN_SP_1 Read the internal setting temperature (if 0: internal control)
Read the external setting temperature (if 1: external control)
IN_SP_3 Read the safety setting temperature
IN_SP_4 Read the pump setting speed
IN_TMODE Read temperature control
0: internal control
1: external control
OUT_SP_1 xxx Set the internal setting temperature XXX (if 0: internal control)
Set the external setting temperature XXX (if 1: external control)
OUT_SP_12@n Set the WD safety temperature with echo of the set (defined) value.
OUT_SP_4 xxx Set the pump speed XXX
OUT_SP_42@n Set the WD-safety speed with echo of the set (defined) value.
OUT_TMODE_0 Set to Internal temperature control
OUT_TMODE_1 Set to External temperature control
OUT_WD1@n Start the watchdog mode 1 and set the time for the watchdog to n (20...1500) seconds.
Echo of the Watchdog time.
During a WD1-event, the heating and pump functions are switched off.
This command needs to be send within the watchdog time.
OUT_WD2@n Start the watchdog mode 2 and set the watchdog time to n (20...1500) seconds.
Echo of the watchdog time.
During a WD2-event, the set temperature is changed to the WD safety temperature and the pump set
speed is set to the WD safety speed.
This command needs to be send within the watchdog time.
RESET Reset the PC control and stop the device functions.
START_1 Start the heating function
START_4 Start the pump function
STOP_1 Stop the heating function
STOP_4 Stop the pump function
