1 Overview
1.1 Overview
CSC-H64 is a serial to Ethernet/WLAN converter that enables your serial devices to carry
robust networking capabilities. This serial to Ethernet/WLAN converter offers 4 serial ports
interfaced with RS232/RS422/RS485 and a frame delimiter for packet fragmentation.
CSC-H64 comes preloaded with Soft AP so it can simply be linked to any devices with
WLAN by operating as an AP. It eases network construction with mobile devices such as
smartphones, tablet PCs and laptops where an AP is unavailable.
Ensuring reliable operation with industrial temperature range of -40℃~+85℃(without a
USB WLAN adapter), along with an overvoltage, reverse voltage and overcurrent protection
circuit, makes this Serial to Ethernet/WLAN converter suitable for harsh industrial
environments.
 To connect CSC-H64 to wireless LAN, a USB wireless LAN adapter which uses a
RT3070/RT5370 chipset of Ralink Corporation is required.
1.2 Features
Serial to Ethernet and Wireless LAN(IEEE 802.11 b/g) converter
IPv4 / IPv6 dual stack
4 X RS232/RS422/RS485 (D-SUB 9 pin Male, up to 230,400bps)
Infrastructure and Ad-hoc network
Soft AP (setting and connection through a smartphone or laptop without an AP
available)
Security options (Password, SSL, WEP, WPA-PSK, WPA2-PSK)
WPA Enterprise (EAP-TLS, EAP-TTLS, PEAP)
Variety of monitoring status (ezManager, Telnet)
Industrial temperature range (-40℃~+85℃, without a USB WLAN adapter)

2 Installation and Test
2.1 Network Mode
2.1.1 Wired LAN mode
CSC-H64 operates in LAN mode when you connect a LAN cable. To use this mode, you
are required to either remove a USB wireless LAN adapter or set WLAN disabled.
Figure 2-1 Ethernet connection
2.1.2 Wireless LAN Mode
If the USB WLAN adapter is connected, CSC-H64 operates in WLAN mode.
CSC-H64 supports IEEE802.11b/g. IEEE802.11 standard that is called Wi-Fi has three
network topologies: Infrastructure, Ad-hoc and Soft AP mode.
For security, CSC-H64 supports WEP, WPA-PSK and WPA-Enterprise (EAP-TLS/TTLS, PEAP).
 To connect CSC-H64 to wireless LAN, a USB wireless LAN adapter which uses a
RT3070/RT5370 chipset of Ralink Corporation is required.
