802.11 b/g ). Serial to Wi-Fi Converter is designed to operate serial ports through wireless (Wi-Fi 802.11
b/g). The data is transmitted via TCP/IP protocol. Therefore control is available via Ethernet, Intranet and
Internet. Serial to Wi-Fi Converter is packaged in a case well suited for industrial environments. All serial
ports operate in common RS-232 mode, industrial RS-422 and RS-485 modes configuration.
With the maturity of Wi-Fi technology of 802.11b/g, delivering cost effective becomes increasingly
important. Model EX-9486C-W of Serial to Wi-Fi converter product is a more competitive price by careful
selecting high quality with competitive prices components in the world, the product design is adopted ARM
single-chip, made network connectivity possible with affordable cost for virtually all kinds of devices. This

Product Features
Data Conversion between RS-232/422/485 and Wireless Lan
Convert serial device (RS-232, RS-422, RS-485) data/signal into the TCP/IP package data/signal
and send them out with the Ethernet DataStream via Wi-Fi wireless; or convert the TCP/IP package
data/signal into serial device data/signal.
Wi-Fi Wireless LAN(802.11 b/g)
It based on the latest industry standard Wi-Fi Certified IEEE 802.11b / g specification; it offers
maximum channel speeds of up to 54 Mbps. The Wi-Fi function maintains interoperability within the
2.3~2.5 GHz frequency band, offering full compatibility with 802.11b / g networks. This integrated
wireless solution of Serial to Ethernet Converter is widely deployed in business environments and is
the standard for wireless access in public places. It also supports key security features like Wi-Fi
Protected Access (WPA), WEP and 802.1x.
Dynamic IP Configuration
Support DHCP client mode, simplifying network address configuration and management.
Server / Client Dual Modes
Series can be configured as network server or network client. In the client mode, it can be installed in
network which is protected by NAT router or firewall, without the need of a real IP address.
Web-based Setup
Parameters setup is based on HTTPS protocol by using standard browsers (IE and Netscape). No
special software would be required. To use https to enter Web-Server of converter
(For example https:∕∕192.168.1.100)
Built-in Security Control
It is protected by both setup password and access password to prevent intruders.
Remote updated
Firmware can be reprogrammed directly via Ethernet network to keep up with latest network
standards.
