Master controller setting step
1. IDNO= 0, PSL= TAIE
2. BITS= O_81, BAUD= 9600
3. SET0.1= 1
4. SET0.2= 0
5. After completing the above steps, master controller start to transmit SV to slave controller SV
Slave controller setting step
1. IDNO= 1, PSL= TAIE
2. BITS= O_81, BAUD= 9600
3. SET0.1= 0
4. SET0.2= 1
5. RATE= 9999
6. After completing the above steps, slave controller start to receive master controller SV
Notes
1. Afer adding master-slave communication, RS-485 communication not available
2. Master-slave communication only available in TAIE protocol(PSL= TAIE)
3. Master controller does not use parameter RATE, to attenuate the SV received by slave controller just adjust parameter RATE
4. Master controller can connect up to 10 slave controllers, and the wiring between every controller should not exceed 1 meter.
