Contact us Online documentation Product data sheet

ACKSYS widens its wireless solution offer by introducing the WL-DONGLE-OEM, a compact wireless serial to WiFi Ethernet module for OEMs with TTL or RS232 serial interface.

WL-DONGLE-OEM relies on the same technology used in the WL-COMETH range and thus profit from proven technology, device is very compact and is specially designed to satisfy the needs of the OEM and system integrator markets.

Product rely on the IEEE 802.11b standard (2.4 GHz) and is IEEE 802.11g compatible, it features a full high speed serial interface (up to 250 Kbps) available on a SUBD 9 connector for RS232 model or on a 16 pins HE10 connector for the TTL model.

The link is made safe by a WEP 64/128 bits encryption key, the nominal range is 200 m (open space) for a 11 Mbps binary rate, emitter power is +15dBm while receiver sensitivity is -84dBm.

Its size is extremely compact (L:76 x W:50 x H:18 mm) in order to be integrated in any equipment equipped with a serial port, consequently opening to equipment access to the wireless world.
It can be connected the a printed circuit board through a female HE10 connector or even through a flat cable.

It can be powered from the DC power source (+3.3VDC or +5VDC), consumption doesn't exceed 3W.

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.

Device administration is achieved by using the web browser installed on your computer or from TELNET.

Note (1): Only one of the two power pins +3.3VDC (pin 2) or +5VDC (pin 15) should be used simultaneously to power the WL-DONGLE-OEM. Powering from the +3.3VC power pin apply power directly to IC as the +5VDC go through a power regulator.

Remote COM port mode Works with Windows 9x/me/NT/2K/XP, Linux and requires a COM port redirector driver software on the PC (VIP). This mode is supported by the WL-DONGLE-OEM when running the "ServerCom" firmware and when configured in the TELNET RFC 2217 mode (TELNET RFC 2217 is a standard). This mode makes it possible to run any Windows COM applications without any adaptation (Hyperterminal for example), basically designed for a local COM port, the Windows communication API is fully supported. COM port configuration is carried out by the application itself and not necessarily by the administration module. Other redirector softwares relying on the RFC 2217 standard exist for other operating systems. TCP socket server mode This mode works with any operating system supporting TCP/IP. It is supported by the WL-DONGLE-OEM when running the "ServerCom" firmware and when configured in the RAW mode. The WL-DONGLE-OEM is able to answer to TCP connection request on a configurable TCP port (it is thus a server). The application which uses the WL-DONGLE-OEM relies on the SOCKET API and not on the COM API. COM port configuration (speed, characters, flow control) is programmed in the WL-DONGLE-OEM using the administration module. TCP socket client mode This mode works with any operating system supporting TCP/IP. It is supported by the WL-DONGLE-OEM when running the "TCP Client" firmware. The WL-DONGLE-OEM is able to answer a TCP connection request on a TCP port to a server, the IP address of the server is programmed using the administration module. Connection origin can be established from WL-DONGLE-OEM power ON of from the rising edge of the DSR signal. The application which uses the WL-DONGLE-OEM relies on the SOCKET API and not on the COM API. COM port configuration (speed, characters, flow control) is programmed in the WL-DONGLE-OEM using the administration module. TELNET mode This mode works with any operating system supporting TCP/IP and which has a TELNET client software, two cases: Configured TCP port TCP of the Socket TCP Server mode This mode is supported by the WL-DONGLE-OEM when running the "ServerCom" firmware and when configured in the TELNET mode. It doesn't require any application development on the PC, TELNET is the network application ! TCP port #23 This mode is supported by all the WL-DONGLE-OEM's firmwares. When the WL-DONGLE-OEM receives a port 23 connection request, it switches to the administration mode and can thus be configured (speed, mode ...). AD-HOC mode (point-to-point connection: virtual cable) This mode enables to provide a full-duplex serial exchange between two serial equipements through the WL-DONGLE-OEM and without using any access point. However, the point-to-point connection thus carried out rely on IP and no more on the WiFi network substructure, the communication is carried out directly by radio between two WL-DONGLE-OEM equipments like standard radio modems. MODBUS/TCP data gateway mode This mode is supported by the WL-DONGLE-OEM when running the "MODBUS/TCP" firmware. In conformity with the MODBUS/TCP Client / Server specifications, this mode makes it possible to connect any serial MODBUS equipments (MODBUS/ASCII & MODBUS/RTU) to the wireless Ethernet TCP/IP network. In this mode, the WL-DONGLE-OEM settles like a radio bridge between the wireless Ethernet network and the serial MODBUS equipments which dramatically simplifies the extension from traditional MODBUS installation to a MODBUS/TCP based installation on the wireless Ethernet network. The WL-DONGLE-OEM device can work as a slave or master device on both sides (Wireless Ethernet or Serial). This mode also makes it possible to connect between them and in a transparent way several traditional serial MODBUS equipments through the wireless Ethernet network. WL-DONGLE-OEM with MODBUS/TCP allows moreover integration within the same network of serial MODBUS/ASCII & MODBUS/RTU based equipments and MODBUS/TCP equipments. Some illustrations
