Input communication interface
232: Output is RS-232 interface
485: Output is RS-485 interface
232/485: Output is RS-232 or RS-485 interface (Automatic setting which one )

Note: When the interface is 232/485. It defaults to RS-485 output. User can switch between RS485 and RS232 by pushing down buttons inside the chassis. Opening the chassis. It shows two buttons on the circuit board. When both buttons are pushed down. Output is RS232; The contrary. Is RS485 output.

Model Selection examples:
1. ISODA O1-485 Means 4-20ma signal output. intput is RS485 interface
2. ISODA O4-232 Means 0-5V signal output. intput is RS232 interface
3. ISODA O7-232/485 Means 0-± 5V signal output. intput is RS485 or RS232 interface.
