Wireless servers offer flexibility

Built-in ESD surge protection is added on every signal to safeguard serial devices from electrical interference, surges or spikes that could interrupt the system operation.

The PSx10W wireless device server line offers an 802.11b/g type wireless network interface, WPA2 and 802.11i-compliant wireless security, a flexible operation mode, TCP/UDP multicasting, telnet COM port control protocol support and port event handling for wireless device networking.

The range includes PS110W HelloDevice Pro110 single-port wireless device server and the PS210W HelloDevice Pro210 two-port wireless device server.

The PS110W/PS210W incorporates a 802.11b/g type wireless network interface.

It has a 10/100Base port for backup configuration purposes.

The PS110W/PS210W supports both infrastructure and ad-hoc (peer-to-peer wireless networking) operation modes.

When working in infrastructure mode, the PS110W/PS210W transmits serial device data to the host PC via an access point.

The ad-hoc mode provides a full-duplex serial exchange between serial devices through the PS110W/PS210W, without using any access point.

The PS110W/PS210W support RS-232 serial devices via RJ45 type connector and supports data transfer speeds (baud rate) from 300bit/s to 460Kbit/s.

Built-in ESD surge protection is added on every signal to safeguard serial devices from electrical interference, surges or spikes that could interrupt the system operation.

The PS110W/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 PS110W/PS210W supports standard 64/128bit 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 organisation's wireless LAN infrastructure.

In TCP mode, the PS110W/PS210W supports a 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, detect line signal changes, and receive and transmit data.

In addition, when working with Serial/IP COM port redirector, the PS110W/PS210W transmit all serial signals including DTR, DSR and DCD.

In modem emulation mode, PS110W/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, using wireless mobility and bandwidth to eliminate dedicated modems and phone lines.

The TCP/UDP Multicasting feature involves a serial device sending messages to many PC hosts simultaneously.

The PS110W/PS210W has a Wi-Fi signal strength display, as well as LED indicators for power and status.

The PS110W/PS210W is suitable 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.

Integrating the PS110W/PS210W into a control or automation system allows reduced cabling costs and increased mobility.
