9.1 RS communication protocol for LAMBDA VIT-FIT, PRECIFLOW, MULTIFLOW, HIFLOW, MAXIFLOW & MEGAFLOW pumps9.2 Examples9.3 How to set the Pump address?9.4 RS-connection scheme9.5 RS communication protocol for the on-board INTEGRATOR (optional)
The PC sends: #0201r123EEcr
The control sum (checksum) qs is made in the following way (only the last byte (2 ASCII characters of the type 0…9ABCDEF) is taken):
Speed: 2400 Bd (Baud) 8 data bits, odd parity, 1 stop bit
Address of the PC: 01
Address of the pump: 02
The PC sends: #0201r123EEcrThe pump will move the pusher to the left (infusion) at the speed of 123.
The PC sends: #0201G2DcrThe answer of the pump: <0102r12307cr
The PC sends: #0201l123E8crThe pump will move the pusher to the right (filling) at the speed of 123.
The PC sends: #0201s59crThe pump stops.
The PC sends: #0201g4DcrThe pump will go to the local command (pump front panel is activated).
To look up/modify the instrument address, disconnect the pump from the mains.
While keeping the direction button ◄|► pressed connect the pump to the mains again. The message “A” and two numbers will appear on the display. This number from 00 to 99 is the current address of the pump.
To change the address press the buttons Λ Λ Λ under the display until the desired number is obtained.
To confirm and save the address, press the ON/OFF button.
