1. Introduction
The ALM-06-WF have WLAN connection complies with the IEEE802.11b/g/n
standards. With the popularity of 802.11 network infrastructure, the ALM-06-WF make
an easy way to incorporate wireless connectivity into monitoring and configuration.
They also support Modbus TCP protocol and the network encryption configuration,
which makes perfect integration to SCADA software and offer easy and safe access for
users from anytime and anywhere.

1.2.1 Features Description
The ALM-06-WF offers the most comprehensive configuration to meet specific
application requirements. The following list shows the features designed to simplify
installation, configuration and application.
Compatible with IEEE 802.11b/g/n standards
ALM-06-WF complied with IEEE 802.11b/g/n standard from 2.4~2.5 GHz, and it
can be used to connect your wireless LAN.
Support Access Point(AP) & Station(STA) modes for wireless networks
AP mode lets you create a Limited AP(1 Client access allow) network with the
specified SSID to communicate directly with each other without the need for a wireless
access point.
STA mode is the more common network configuration where all wireless clients
connect to the wireless network via a WAP (Wireless Access Point).
Support WEP, WPA and WPA2 wireless encryption
WEP and WPA are common types of security that are used to protect wireless
networks. When WEP or WPA is turned on, ALM-06-WF uses a special security key
combination to allow only devices that know this key to connect to its wireless network.
This applies to laptops, smart device, or any other wireless device.
Support Modbus TCP protocols
The Modbus TCP server function on the ALM-06-WF can be used to provide data
monitoring from HMI/SCADA software built with Modbus TCP driver.
Also there is some other HMI Modbus App in Android Google Play you can use.
Built-in MP3 Audio decoder & Output
The Alarm sound output using MP3(MPEG1-Audio Layer Ⅲ) audio, it support most
of MP3 format(Sample Rate 24/44.1(prefer)/48 KHz, Bit Rate 32 64 96 128(prefer) 160
192 Kbit/s), include an 3W audio power amplifier & 1KΩ Impedance Line Out can send
the alarm sound to external PA(Power Amplifier) system.
Support 6 channel trigger input with 8 alarm mode
Include 6 channel Photo couple input & 8 kinds of mode for trigger alarm, it also
can be trigger an extend device using external Relay Output. All modes & MP3 audio
files can be monitoring, configuration & download from PC Utility, it also can monitor
status form Android APP.
