Quatech SSEW-400D serial server

Wireless, 802.11b/g, 2.4 – 2.4835 GHz, 1 x DB-9, RS-232/422/485, LAN 10/100BaseT, 64/128-bit WEP/WPA 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.
