Explanation
LEDx?
▪ LED=0000\r\n
▪ LED=0001\r\n
Select parameter: x=0-7
▪ LED off
▪ LED on
LED0?=Volume ml
LED1?=Flow ml/min
LED2?=Tube mm (inner diameter)
LED3?=Speed rpm
LED4?=Rotation
LED5?=Direction of rotation right
LED6?=Direction of rotation left
LED7?=Pause sec/min/h (intermittent pause)
DSP?
DSP=xxx\r\n Display query: show actual value
TAx!
- Select function key: x=1-7
TA1!=Cal (calibrate)
TA2!=Start/Stop (rotation key)
TA3!=Change direction of rotation
TA4!=Max (maximum speed)
TA5!=Up (arrow key)
TA6!=Down (arrow key)
TA7!=Select (select key)
SPx=xxxx!
- Set intermittent pause: x=0;2;3
SP0=0001 - 5999 seconds/10 e.g. 100 milliseconds
SP2=0010 - 0599 minutes
SP3=0010 - 0750 hours
SMM=xxxx!
2)
- Flow ml respectively μl (tube dependent):
xxxx=000.0 - 9999
SDZ=xxxx!
- Set rotation rpm:
xxxx=0000 - 9999 (min/max gear dependent)
SDM=xxxx!
2)
- Volume dosing ml e.g. μl (tube dependent):
xxxx=000.1 - 9999 (not allowed for calibrating)
SSD=xxxx!
2)
- Set inner tube Ø : x=4digit gure
xxxx=0000 (see following section
“Interface commands: set tube”)
-
OK\r\n Command successful
-
ERROR\r\n Command failed
-
PO/r/n Dosing completed
