This board is equipped with a Lantronix XPort Module. The Lantronix communications module adds Ethernet communications to the board. The module will connect to a your router with a standard CAT-5 cable. 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. Lantronix XPort Datasheet
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 (ProXR Enhanced 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 Ethernet devices, customers may experience loss of communications until the device is reconnected. Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.
Wi-Fi Adapter Available
Make this ethernet controller Wi-Fi compatible by simply connecting the Netgear WNCE2001 Universal Wireless Internet Adapter. The WNCE2001 will connect any of these Web Relay devices to an existing 802.11 wireless network. Installation couldn't be easier with Netgear's CD-less, wireless installation. The Netgear WNCE2001 can be purchased on your own or select the Wi-Fi option at checkout to add to your order.
