Q. What is SeriaLynx?
A. SeriaLynx is an 802.11 Wireless Adaptor for Palm, Windows CE and RS-232 RS-422 and RS-485 Serial Devices: a communication device which provides an interface between Serial Data communication devices and IEEE 802.3 Ethernet networks. SeriaLynx can also utilize its on-board wireless capability to add wireless networking capability that complies with IEEE 802.11 specifications. SeriaLynx devices can operate in four different modes: 

1. Using RJ45 10baseT cabling to connect a Serial Data Device to wired devices on a LAN (Local Area Network).
2. Wireless in an ad hoc mode enabling direct communication between two Serial Data Devices each connected to an individual SeriaLynx unit.
3. Wireless with a access point functioning as a bridge between a serial data device and a server on a LAN, or with full peer-to-peer access on a LAN.
4. Wireless with a access point functioning as a gateway to a stand-alone WLAN (Wireless Local Area Network) that permits full peer-to-peer communication between the other devices on the 802.11 network.

Q. Why does a SeriaLynx Unit have two DB9 COM ports?
A. Although each SeriaLynx unit has its own configurable IP address, the unit can accept two different port numbers so that each unit can  be connected to two Serial Data Devices. The IP address and the port number are easily configured using the simple setup utility.

Q. How do I configure a SeriaLynx Unit?
A. There are three different ways of configuring a SeriaLynx unit:

1. You can use the supplied Null Modem cable to connect your SeriaLynx unit directly to a Windows 95/98/ME/NT computer. Then it is a simple matter of entering the required information.
2. You can connect the SeriaLynx unit to your Local Area Network, or even from a device connected to the Internet and use a Web browser like Internet Explorer or Netscape to configure the settings.
3. You can TELNET to the SeriaLynx unit either from your LAN or, if connected, even from a device connected to the Internet.

Q. What is the range of the Wireless connectivity?
A. This is dependant on local conditions and the capabilities of the access point - antenna, power output, etc.; however, with a suitable access point and optimum terrain, SeriaLynx will operate up 1000ft or further.

Q. What is the IEEE 802.11b standard for Wireless LAN (WLAN)?
A. The IEEE 802.11b standard for Wireless LAN, also known as Wireless Ethernet, is a technical specification written for wireless network technology that uses 2.4 GHz radio frequency (RF) to transmit data. It allows users to access information at home, in the workplace or on campus without wires. The technology is most often used to extend the coverage of a wired LAN, but it can also be used in place of wired networks. The installation of access points (radio transceivers) provides wireless coverage across a local area. Client adapters and access points communicate to transmit data without wires within a WLAN. A Wireless LAN can also exist in a peer-to-peer setting, between devices that have WLAN access modules. SeriaLynx supports peer-to-peer networking among other Wireless Ethernet devices. Adherence to the 802.11b standard increases compatibility among WLAN products.

Q. With which access points will a SeriaLynx work? 
A. The SeriaLynx Wireless Ethernet module will work with all brands of 802.11b access points that are Wi-Fi compatible.

Q. What is the estimated battery life of the SeriaLynx unit.
A. SeriaLynx comes equipped with a rechargeable NiMh battery that will run for approximately four hours of continuous wireless use. 

Q. What is the warranty for SeriaLynx units?
A. All SeriaLynx units carry a one-year limited hardware and software warranty.
