Ethernet Relay
The ZADR220ProXR_ETHERNET Ethernet Relay has an Ethernet interface that plugs intro a router using a standard CAT5 cable where it is assigned an IP address. Once on the network, commands can be sent to control the relay from within the network or from outside through the internet. The board supports virtual COM port over ethernet, direct TCP/IP communications, DHCP and fixed IP Address.ZADR220ProXR_ETHERNET The Ideal Choice
The ZADR220ProXR_ETHERNET Ethernet Relay is an ideal choice for controlling relays over a network. The main method of communication is a standard TCP Socket This communication protocol makes use of Network Sockets to create point to point tunnels that data can flow through bidirectionally. Commands can be sent to the board and shortly thereafter receive a response through the same Socket.Ethernet Relay - ProXR
This is a ProXR board meaning that it has the industry leading command set and the board can be expanded to include up to 256 relays. Adding relays is as easy as easy as adding expansion boards as your needs arise.

Ethernet Relay Control
Our Ethernet Relay make it easier than ever to add computer controlled switching to your network or over the internet for your most demanding applications. Simply connect this controller to your router and the router will assign it an IP address. Once the IP address has been assigned the Lantronics XPort firmware will give you powerful communication options for full network relay control.
DHCP and Static IP Addresses
This module supports both DHCP and static IP Addressing. For communications reliability, especially via Remote Access, we recommend using a Static IP Address when you feel comfortable doing so. This will ensure that the device will always be where you expect it to be when you try to connect to it.Lantronix XPort
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
TCP/IP Communications
The main method of communication to the Ethernet modules is a standard TCP Socket. This communication protocol makes use of Network Sockets to create point to point tunnels that data can flow through bi-directionally. In this way the computer that is controlling the relay can send commands and shortly thereafter receive the response through the same Socket.Switch/Direct Connection
By default Lantronix XPort Pro modules are in DHCP mode meaning they must connect to a DHCP server in order to obtain an IP address. If your device will be connected to a switch or directly to a computer where DHCP is not available you must store a static IP address to the device using the instructions in this guide. Note that storing a Static IP address to the controller will require initial connection to a DHCP Router; it is absolutely not possible without it. Once the controller has a Static IP address you can connect it to a network switch and make connection to it via that static IP. If you wish to connect the device directly to a computer you will need a cross over Ethernet cable.Port Forwarding
When using this board over the internet and outside the Local Area Network, Port Forwarding will be required. Port Forwarding is a protocol used by your router to allow incoming requests for connections to get through to a specific device on a specific port. Below is an example of how it works. In this example a router has been setup to forward incoming requests for port 2101 to the device at the IP Address 192.168.2.19 on port 2101. Now when any device that tries to access this Port on the External IP Address the router will see the request and automatically forward the request to the device at the IP Address of 192.168.2.19 on port 2101. If this Port Forwarding rule was not in place and a request came in on port 2101 the router would not know which port or device to forward it to and the request for connection would be denied. Note: Port Forwarding will not be necessary when using this within a Local Area Network. For more on Port Forwarding with detailed instructions for every router visit: https://portforward.com/ .
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.Induction Suppression
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.

Applying Good clean power to the board is essential for the operation of the board. Not only for the switching of the relays but the firmware that processes the commands. Without good steady clean power from a regulated power supply the board simply will not function correctly. All boards on the site require 12 VDC power. The PWR12 US power supply is a 120VAC to 12VDC 1.25A 60Hz regulated power supply and it plugs into the barrel connector on the board. The output connector is a 2.1mm I.D. x 5.5mm O.D. x 9.5mm Female R/A barrel connector. We also carry an international power supply with interchangeable adapters for international customers.

Add Relays as Your Needs Grow
The ProXR series controllers are expandable up to 256 total relays. The controller is fitted with an XR Expansion Port where you can add expansion boards to this relay. Expansion boards can be added until you reach 256 total relays. The Expansion Boards get their logic from the main board and will require 12 VDC power. Expansion boards do not need to be the same relay amperage as the main board or other expansion boards.Read Analog Sensors
This ProXR controller offers a 8-Channel 8/10-Bit Analog to Digital Converter in addition to relay control. This board is equipped with 8 inputs that can accept an input from 0 to 5 volts. The boards AD8 Command Set is used to read the analog voltages and converts the Voltage from 0 to 5 Volts DC into numeric value. The AD8
Command Set supports 8-Bit Analog to Digital Conversion, which converts 0-5VDC to a numeric value from 0 to 255. The AD8 Command Set also supports 10-Bit Analog to Digital Conversion, which converts 0-5VDC to a numeric value from 0 to 1023.
16 User-Programmable Timers
The ProXR Series controllers have 16 user-programmable timers. Each independent timer can be assigned to any relay, and can be programmed to hold the relay in the On state, or to pulse the relay at the end of the timer. The ProXR timing features are ideally suited for Watchdog, Keep Alive, and Server Reboot applications, as well as sprinkler systems, gate openers, and lighting applications. Relay Timing Features support two modes of operation: Duration and Pulse. Duration timing is ideally suited where a device should be activated for a period of time. Pulse timing mode is designed specifically for server reboot applications, whereby, if the timer is not reset periodically by your software, the timer will run out and reboot your computer.Easy Software Development
