To use Sphera in a MODBUS network it is necessary to
address the RS-485 MODULE by S3, S4, S5 ; allowed and
valid addresses from 1 to 127
S5 - it sets the address hundreds :
ON = 100, OFF = 0
S3 - it sets the address dozens
S4 - it sets the address units
S1 - 485 terminator : ON = termination YES
S2 - line polarizer
Inside the 485 network must be polarized only one
board, usually is polarized tha master, i.e. the PC; in
this case S2 = OFF
= polarization NO
If more cards are polarized, faults occur
