ACKSYS renews its serial to wireless solution offer by introducing the WLg-DONGLE, a compact wireless RS232 serial to WiFi Ethernet server with support for 2.4 GHz and 5 GHz radio bands, available from CrispTech .

WLg-DONGLE relies on the same technology used in the "WLg-xxx" series and profits from proven technology. The device is very compact and is specially designed to satisfy the needs of the system integrator market.

Relying on the IEEE 802.11 a/b/g/h standards (2.4 Ghz & 5 Ghz), it features an full high speed serial port (250 Kbps). The radio link is made safe by using most modern methods of protection: WEP 64/128 bits, WPA-PSK, WPA2-PSK and authentification IEEE 802.1x (RADIUS). The nominal range (open space) of the module is 300 m for a transmit power of +20 dBm and -92 dBm in reception (a/g modes) and -95 dBm (IEEE 802.11b mode).

This module supports the following modes : TCP Client / Server, TELNET RFC2217, COM port redirection, TELNET server, raw, point to point (virtual cable) and the serial MODBUS to MODBUS/TCP gateway.

Easy configuration and administration with web browsers, TELNET, SNMP and from the ACKSYS administration software NDM.
