SENA is pleased to introduce an upcoming 2-port Wireless Device Server, PS210W, with competitive edge features such as flexible operation mode, TCP/UDP multicasting, telnet COM port control protocol support (RFC2217 compliant), SSL encryption, and port event handling for wireless device networking.

Wireless Network Interface:
• On the network interface side, the PS210W incorporate 802.11b/g type wireless network interface. In addition, it has a 10/100Base port for Backup Configuration purposes. The PS210W supports both infrastructure and ad-hoc (peer-to-peer wireless networking) operation modes. When working in infrastructure mode, the PS210W 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 PS210W and without using any access point.

Serial Interface and Surge Protection:
• On the serial side, the PS210W support RS-232 serial devices via RJ45 type connector and supports data transfer speeds (baud rate) from 300 bps to 460 Kbps. Built-in ESD surge protection is added on every signal to safeguard your serial devices from electrical interference, surges or spikes that could interrupt the system operation.

Strong Security:
• The PS210W provides enterprise-class WPA2 (Wi-Fi Protected Access) and 802.11i compliant wireless security through advanced AES encryption for complete data privacy and secure mutual authentication services. Further, the PS210W supports standard 64/128-bit WEP (Wired Equivalent Privacy) protocol to protect data being transmitted over a wireless LAN network.

For secure data communication between a client and a server, SSL and RC4 encryption features are provided. In addition, HTTPS for secure data transfer over the web, and IP filtering controls the access to serial devices.

These security features enable customers to connect virtually any serial device and securely collect, track, measure, monitor and control critical device information through an organization's wireless LAN infrastructure.

Telnet COM port control:
• In TCP mode, the PS210W supports telnet COM port control option (RFC 2217 compliant) that is used to access serial devices over the network. This option enable user applications to set the parameters of remote serial ports (baud rate, flow control, etc.), detect line signal changes, as well as receive and transmit data. In addition, when working with Serial/IP COM port redirector, the PS210W transmit all serial signals including DTR, DSR and DCD.

Modem Emulation:
• In modem emulation mode, PS210W is used to replace dial-up modems. The unit accepts modem AT commands on the serial port, and then establishes a network connection to the end device, leveraging wireless mobility and bandwidth to eliminate dedicated modems and phone lines.

TCP/UDP Multicasting:
• TCP/UDP Multicasting feature is provided for those applications, which involve a serial device sending messages to many PC host simultaneously.

Lower Latency:
• When working with the Serial/IP COM port redirector, the PS210W generates lower overall latency that is required to operate industrial and control applications reliably, with maximum throughput.

Wi-Fi Signal Strength display:
• The PS210W also provides you with full-featured Wi-Fi Signal Strength display via LEDs. Further, the unit comes with LED indicators for Power, Status and act of Wi-Fi link, and Serial Rx/Tx signals.

Application Areas:
• The PS210W is ideal for connecting devices used in M2M automation applications such as industrial applications that require data logging, wireless sensor control and monitoring in production facilities, building and point-of-sale, warehouse, and medical applications where running Ethernet cables is not practical or possible.

Benefits:
• Integrating the PS210W into a control or automation system benefits in reducing cabling costs and increased mobility.

If you're looking for a cost-effective, secure and scalable means to wireless-enable your serial devices, look no further than PS210W from SENA. The PS210W is expected to be released in August 2007.
