1. Introduction
1.1) General Description
The E2S enables the serial target device to have an Ethernet function. Therefore, the
serial target device is able to connect a LAN/ WAN immediately without any hardware change.
The E2S is able to translate the protocol from TCP/IP packet to a kind of serial data
stream just likes RS-232, RS-485, UART-TTL or SPI depends on the different E2S model.
On the other hand, E2S is also to translate the data stream from a serial to TCP/IP packet.
It provides an easier way to connect Ethernet by DHCP client or DNS client. Besides, a
customized web page can configure E2S for an adaptive setting.
1.2) System Architecture
Figure 1. System Architecture.
1.3) Ordering Information
Part number : FR-E2S-xy
Serial interface:
• x =〝U〞- interface Uart-TTL.
=〝R〞- interface RS232.
=〝S〞- interface RS485.
=〝P〞- interface SPI.
• y =〝F〞- Commercial version.
=〝I〞- Industrial version.
