6  APPENDIX 

6.1  RS communication protocol for LAMBDA REDOX Potential 

measurement unit 

6.1.1  Communication settings: 

Speed: 

2400 Baud 

Data format: 

8 bit, odd parity, 1 stop bit 

Transmit-Receive switching: 

DTR (usually automatic switching) 

Transmit-Receive interval: 

10 ms 

 

 

 

6.1.2  Data format for transmission from the computer (master): 

# ss mm 

G

 qs c 

send data 

# ss mm 

M

 qs c 

send data 

 

where: 

ss 

is the address of the slave receiver 

mm 

is the address of the transmitter (master) 

M

 or 

 

command to send data 

qs 

control sum 

carriage return CR (ASCII 0D) 

 

 

 

 

 

 

6.1.3  Data format for transmission to the computer (master): 

< mm ss a ddd qs c 

where: 

a

 

– for positive value 

– for negative value

 

ddd

 

data (3 ASCII number 0.......9 - transmission from high to low)

 

qs

 

control sum in hexadecimal format (2 ASCII symbols 0.......9 A B C D E F) 

 

 

 

 

 

 

6.2  How to set the REDOX measurement unit address? 

To look up/modify the instrument address, disconnect the 8-pole cable from the REDOX 
measurement unit. 

Press the 

ADRS

 button continuously and at the same time connect the 8-pole cable to 

REDOX measurement unit again. The message 

“A”

 and two numbers will appear on the 

display. This number from 00 to 99 is the current address of the powder dosing instrument.  

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 

OK

 button.
