Server puts serial devices securely on Ethernet
IALink from Sena Technologies is an industrial device server that enables Modbus-based serial devices to be connected to Ethernet.
SSL-equipped serial-Ethernet convertor
POSLink from Sena Technologies is an SSL-equipped serial-Ethernet convertor for leased-line based credit card payment terminals connected to broadband Internet.
On the serial side, the unit features a nine-pin male DB-9 connector, 9-30V DC input, and supports data transfer speeds up to 115Kbit/s.
The LS100W supports both infrastructure and ad-hoc (peer-to-peer wireless networking) operation modes.
When working in infrastructure mode, the LS100W transmits serial device data to the host PC via an access point.
Ad-hoc mode provides a full-duplex serial exchange between serial devices through the LS100W and without using any access point.
The LS100W uses standard 64bit WEP (Wired Equivalent Privacy) protocol to protect data being transmitted over a wireless LAN network.
The LS100W supports COM/TTY drivers for Windows and Linux systems, ensuring that existing PC software will still work when used with the new wireless LAN infrastructure.
TCP server and TCP client modes are also supported, so that IP-based software can access the serial device directly by knowing the IP address and TCP port number.
The unit comes with LED indicators for power, status and act of Wi-Fi link, and serial Rx/Tx signals.
In addition, the device server supports both wall and DIN rail style mount kits for flexible installation.
The LS100W is suitable for connecting devices used in M2M automation applications such as industrial, building and point-of-sale where running Ethernet cables is not practical or possible.
Integrating the LS100W into a control or automation system benefits in reducing cabling costs and increased mobility.
Further, the serial data are routed using IP addressing which means the data can be forwarded using a wireless or wired or LAN.
