Connecting to Secure I/O 2
Secure I/O 2 is an I/O device, can be connected to AE-M with the RS-485 cable. Security can be maintained even if the connection
between AE-M and Secure I/O 2 has been lost or the power supply to AE-M has been shut off due to external factors.
 Use the RS-485 cable with AWG24, twisted pair, and less than 1.2 km in length.
 If connecting with a RS-485 daisy chain, connect the termination resistor (120 Ω) to both ends of the daisy chain connection. If
connected to the middle line, the signal level becomes smaller and the communication performance will deteriorate. Make
sure to connect it to both ends of the daisy chain connection.
