To save the configured value, bits S1 and S2 must be set to OFF.
Stop bit: S1=1; S2=0
Procedure:
- Set all dip switches to 0 except dip 1;
- Power up the instrument;
- Wait a few seconds until the LED_On flashes;
- Carry out the desired
programming
(see below);
- Set dip 1 to 0 and wait for the LEDs: Run, Ain1 and Ain 2 to light up;
- Switch off the instrument;
- Set the Baud rate and the desired address;
- Power up the instrument.
As long as dips 3 to 8 are at 0, the LEDs LED_Run, LED_Ain1 and LED_Ain 2
indicate the current stop configuration according to the following table:

ATTENTION: It is not possible to set the "data bit" differently from the 8 bits as the
Modbus RTU protocol requires data in this format.
