Interface type: - Isolated (50 V) RS-485;
- Not isolated TTL;
Voltage levels: According to EIA standard;
Protocol type: MODBUS RTU;
Byte format: 8 bit with no parity;
Stop bit: 1 (one);
Baud rate: Programmable between 1200... 38400 baud;
Address: Programmable between 1... 255.
Notes: 1. RS-485 interface allows to connect up to 30
devices with one remote master unit.
2. The cable length must not exceed 1.5 km at
9600 baud.
3. A description of the signal sense of the voltage
appearing across the interconnection cable as
defined by EIA for RS-485 follows:
• The “A” terminal of the generator shall be
negative with respect to the “B” terminal for a
binary 1 (MARK or OFF) state.
• The “A” terminal of the generator shall be
positive with respect to the “B” terminal for a
binary 0 (SPACE or ON).
