Chapter 2 SI-65(A/FA) Usage
2-1. SI-65(A/FA) Overview and Features
SI-65 is a DC powered model. SI-65A is a DC powered model which is adaptive to cold
district. SI-65FA has a built-in AC power supply and has a insulator between the interfaces
(Ethernet and the RS-422/485). These three models have the same function as to the conversion
function. You can set an IP address to the converter and the converter communicates with the
Ethernet device by TCP/IP or UDP/IP. When it receives data from serial side, it transmits the
data by putting it on the data part of the TCP/IP or UDP/IP packet. When it receives data from
the Ethernet side, it extracts the data part of the TCP/IP or UDP/IP packet and transmits it to the
serial part.
