Serial to 802.11b/g Wireless Networking with Superior Performance and Security

All Quatech Airborne wireless device servers offer a simple, integrated configuration process, and the embedded 802.11b/g wireless radio offers superior power and receive sensitivity. Combined with the industry's best processor, a PowerPC® from Freescale™, these models incorporate a world-class architecture that ensures compatibility with market-leading wireless infrastructures, boosts throughput and reduces latency to the lowest levels possible. This allows a broader range of serial devices to communicate over a wireless Ethernet network without modifying host software designed to use COM ports.

The SSEW-100D and DSEW-100D, wirelessly network-enable one or two RS-232 serial devices, respectively. Two other models, the SSEW-400D and the DSEW-400D, provide wireless network access to RS-232, RS-422 and RS-485 devices and are software-selectable for each individual port. The remaining two models, the SSEW-100D-5V and DSEW-100D-5V, provide +5 VDC power out on the industry-standard DB-9 serial connector. These models can power many RS-232 devices such as barcode scanners and RFID readers through the serial port, eliminating the need for a dedicated power supply for those devices even while connecting them to a wireless network. Surge suppression is available on the 100D and 400D models and is standard on the 100D-5V models.

A CNC (Computer Numerical Control) is a small thin computer that delivers movement instructions to machine tools. These machine tools are typically large, high speed, enclosed metal-working machines used to cut, drill, punch or shape metal into usable objects. These machines usually run at high speeds, and in fact have cooling systems built-in that shower the high-speed tools with coolant as they operate on the metal. The CNC operates the interchangeable tools in the machine, telling the tool how many thousandths of an inch to move, drill, sand, cut, etc. at any given time. The instructions tell the machine how to move are entered into the CNC via an RS-232 or RS-422/485 stream from a PC. This eliminates costly errors caused by manually entering the data. The wrong instructions at any given time can scrap a huge piece of metal or break a very costly tool. When a PC has dozens of pages of instructions to deliver to a CNC it drip feeds it one line at a time because the CNC has a small memory buffer and overruns means dropped lines of instructions which means scrap metal or broken tools. Another pitfall to watch out for is when the CNC is paused the information from the PC needs to stop sending data right away. Otherwise when the CNC is restarted any lines of instructions sent during stoppage will not be re-sent. These dropped instructions result in errors in manufacturing.

To build a wireless network for your CNC machines, you can install a Quatech Wireless Device Server at each CNC, Or, you can share one wireless connection among multiple CNC machines by connecting together a Wireless-to-Ethernet Bridge and a multi-port Ethernet/Serial Hub. If you use a bridge, you may also connect computers or printers to the wireless connection. A wireless system also requires one or more access points, which provide the wireless connection to the LAN. Multiple access points may be used in different locations to provide a larger coverage area. The wireless access points can also be used by other 802.11 compatible devices such as portable computers.
