ZB Mesh Contact Closure Detection
Communicate Through an Existing Mesh Network
Monitor and Read Contact Closure Inputs Using a Computer
Monitor Inputs, Trigger Relays for Full Contact Closure Control
Wireless Contact Closure Monitoring
With this Scan Series Controller you can monitor Contact Closure Inputs using a computer. With minimal programming,
data collection and control from a single controller located on your existing mesh network. The SCAN Series command set allows you to read anywhere from 1 to 32 banks of 8 inputs in a single query.
A single bank contains 8 inputs. Reading 32 banks will report the status of 256 inputs. It doesn't stop there, because we are
focused on relay control you can add relays to the board (up to 256) and control them using the data collected from the inputs. Remember
these are contact closure inputs ONLY no voltage can be applied to these inputs.
For the Advanced User
ZigBee Mesh networking is pretty slow, but extremely powerful and very reliable when you follow all the rules. We highly recommend you purchase a ZigBee Development Kit from www.Digi.com before attempting to use this communication technology...ZB Mesh is for the advanced user. But it has the distinction of offering a low-cost Mesh networking protocol...which means wireless data hops around the wireless network until it reaches the destination device...very cool! Very powerful, very long range, but NOT for the timid.
Data Travels Over Mesh Network
The latest Buzz in Wireless Technology is ZB ZigBee. ZB ZigBee is a great way to communicate data throughout buildings (or even across town) because it uses all the devices in the area to make sure your data arrives at its intended destination. ZB ZigBee automatically hops your data all over the ZB ZigBee Mesh Network, transparently forwarding your data to its intended destination. The beauty of ZB ZigBee is that you don't have to do anything except tell it where you want your data to go. The ZB ZigBee Mesh Network handles everything else for you. We have created a page dedicated to helping ZB ZigBee Mesh Network users understand this technology.
So if you are a first time user of ZB ZigBee and you are looking for a great place to get started, see our article!
ProXR Command Set
By combining the power of ZB ZigBee Mesh Networking with our ProXR series relay controllers, you can take advantage of our powerful ProXR command set for data collection and control, in combination with many wireless ZB ZigBee Mesh Networking features. ZB ZigBee is a perfect integration of good speed and excellent reliability, and for the first time, you can now improve data reliability by adding routers between the computer and far away devices.
Here is a quick rundown of what you should expect from ZB ZigBee Mesh Network:
ZB ZigBee Coordinator into the USB Port of your computer. The Coordinator will be used to communicated to your wireless ZB ZigBee Mesh Network. The Coordinator will mount as a COM port on your PC. Open the COM port and start sending data to the Coordinator. The Coordinator will forward your data to any or all devices on the ZB ZigBee Mesh Network.
|A ZB ZigBee Mesh Network consists of up to three components:
Coordinator is Required because it allows your computer to talk to the ZB ZigBee Mesh Network. Use only ONE coordinator in your ZB ZigBee Mesh Network.
|A Router allows data to hop to another part of the ZB ZigBee Mesh Network. It helps contribute to the network, and it can serve as an Endpoint device. In other words, if a relay controller has the Router firmware installed, you can talk to this device directly, or data can be forwarded from this device to another device that may be too far away for the Coordinator to reach directly. Routers are slower than endpoint devices, so use routers wisely.
|An Endpoint device can also be a relay controller or many other types of NCD devices. However, endpoint devices cannot forward data to other parts of the ZB ZigBee Mesh Network. Endpoint devices are faster than router devices, so it is always wise to use Endpoint devices when possible, and router devices when required.

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. When a command was sent to read the status of the contact closure
the status is sent back.
