How to program the 7000 modules? 16 Software Development 2020-04-01

Ans: The user can use any RS-232C device via I-7520 module to send the command string to the 7000 modules and the 7000 modules will echo the result string to the RS-232C device. The data format of command character is given as following :

 

Data format=1_start+8_data+no_parity+1_stop
total=1+8+1=10 bits per character
 

The user shouldn’t change this format to the following invalidate format:

1_start+8_data+no_parity+2_stop       -->  invalidate format
1_start+8_data+even_parity+1_stop    -->  invalidate format
1_start+8_data+odd_parity+1_stop     -->  invalidate format
1_start+7_data+no_parity+2_stop       -->  invalidate format
1_start+7_data+even_parity+1_stop    -->  invalidate format
1_start+7_data+odd_parity+1_stop     -->  invalidate format
