Wi-Fi Wireless Modules
This board is equipped with a Wi-Fi Module. The Wi-Fi communications module adds 802.11b/g wireless communications to the board. The module is powered from the board. The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type Power Supply at checkout. A wi-Fi Configuration kit is available at checkout. Wi-Fi Module Datasheet
Configuring the WiFi Module
Purchase a WiFi Configuration Kit to Configure the Wireless Network of your choice and set your password. This is done through Base Station Software (a free download) and makes configuring the device simple. Just put the Wi-Fi Module into the Configuration Kit, attach the USB port of the Kit to your Computer and open the Base Station Software. After a few clicks simply fill in the information for your wireless network and the module will run through a series of commands and you're ready to control your board. For more information on Wi-Fi configuration see Configuring the Wi-Fi Module.
Easy Software Development
This device supports TCP/IP Communications over a Local Area Network or, if your network is configured properly, Internet Based Communications. Simply attach the device to your wireless network and access it through a socket connection.
Sending Commands Base Station Software is available at no charge to get you up and running fast (more on Base Station below). Once powered up, the controller waits for a ProXR command. A command consists of a few bytes of data in numerical format (see full command set) usually between 2 and 6 bytes. Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command. If a command was sent to read the status of the relay the status is sent back.
Perhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer. Controlling a inductive load using this relay controller requires the use of induction suppression capacitors. The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay. Without this capacitor, the lifespan of the relay will be greatly reduced. Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly. In the case of Wi-Fi devices, customers may experience loss of communications. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.
