The Simplicity of MirC, The Power of .NET
Contact Closure Inputs on Sender Device
Relay Outputs on Receiver Device
Control Distances or Through Walls Where Wireless Can't Reach
Two Boards Working Together
Mir-C controllers are really two boards that allow contact closure inputs on the first board to control relay outputs on a second board. The sending device is equipped with contact closure inputs, the receiving devise is where the relays are. Both sender and relay devices are included when you purchase a Mir-C pair. Contact closures are read on one controller, data is sent to other controller to turn on or off relays, remote device replies back, busy light flashes to confirm data was received at the other end.
MCNET pairs can communicate to each other from anywhere in the world using an internet connection. No Static IP Address is required. Simply plug the Ethernet and Power Cords in and give them a few minutes to find each other. After you wire the controlled devices in, you can control billboard lights in India, Runway Lights at an Airport, or simply lock your front door from the office.
Mir-C devices feature SPDT & SPST relays and are available with the same number of contact closure inputs on the sender as there are relays installed on the remote device. Contact Closure Inputs may only be connected to switches, buttons, or sensors with Contact Closure capability. Not suitable for use in voltage detection applications.

Find the board you need by using the interactive menu below. The Communication Protocols are to the left, this is how the two boards will communicate with each other. Once you decide how they will communicate then select the number of contact closure inputs/relays you would like on the boards. You will be taken to another page where you can simply simply select the board with the correct amperage for the item you are switching.
Find the board you need by using the interactive menu to he right. Hover over the Button and select the communication protocol and then the number of inputs/relays you would like installed.
The sending device is also equipped with LEDs that display the status of the remote relay. Status information is verified using 2-way communications. If communication is lost between the remote relay and the sending device, the sending device will turn off the LED. Additionally, every MirC controller is equipped with a Busy/Ready LED. If the Busy LED flashes, this indicates the remote device has successfully received and accepted your contact closure status. If the Busy LED does not flash, the remote device is out of range.
Communication Between Boards
The MCNET MirC Devices will work on a local area network as well as across internet. There are redundant communication channels between the two boards, as long as one of them is able to make connection, the boards will work. When two modules are in the same local area network, they can communicate to each other directly without a Mirror Server. No Internet connection is required.
Connection Through Mirror Server
When two mirror modules are located in different networks, they can talk to each other through the NCD Mirror Server. Mirror modules can connect to up to four servers at the same time. As long as one of the servers can be connected to, the mirror modules will work. You can use the preloaded servers or you can use the Configuration Utility to customize the board with your own server and three backup servers.
The server can be setup inside a local area network as long as both modules are able to access it.
The "ConfigureUtility" is used to configure the mirror modules.
This program can list all available modules in the same local area network. There is a connection symbol for paired devices.
Multiple Mir-C Pairs?
Multiple Mir-C Controllers can be used in one locations. One Pair of Mir-C controllers will not interfere with another Mir-C pair as they are isolated through the way they are designed. Mir-C Devices are paired together before shipment and will only communicate to each other, for this reason they will not interfere with other Mir-C controllers.
Contact Closure Inputs
A Mir-C Sender controller has as many inputs as its mating Mir-C Receiver has Relays. So a pair of 4 relay Mir-C controllers will have 4 relays on the Receiver board and 4 inputs on the Sender board which are used for controlling the relays on the Receiver Board, the same holds true for 1, 2, and 8 relay versions. Users must NEVER apply any voltage to an input on the Mir-C Sender controller, these inputs are for Contact Closure connection only.
Mir-C Controllers have 1, 2, 4, or 8 Relays integrated into the circuit board. A relay is similar to a switch. The only difference between a switch and a relay is the actual mechanism for changing the on/off status of the switch. On a switch, you manually push on a piece of metal or plastic to operate the switch. On a relay, an electric current is used to operate the switch. Relays do NOT provide a voltage output. They provide a contact closure output, exactly like the terminals found on a light switch at your local hardware store. Wiring to a relay will be slightly different depending on the model of Mir-C controllers you choose.
