• Direct connection: RS232, RS422, RS485
• Modem connection
• 9600, 19200 or 38400 bps, 8 data bits, 1 stop bit, no parity
• Transfer mode RTU
• Function 3 (Read Multiply Registers)
• Function 6 (Write Single Register)
• Function 16 (Write Multiply Registers)
• The response to an incoming message depends on the communication speed. The delay is not shorter
than the time needed to send/receive 3 and ½ characters.
