The BACnet interface option allows the Prodigy Master units to connect to a MS/TP network (sometimes referred to as RS-485). Using the ASHRAE standard BACnet allows interoperability between a new or existing building automation system (BAS). A standard communication protocol such as BACnet will ensure future updates and expansions can be done with minimal problems.

A proprietary system would only allow products to be networked if they are all from the same company. This can cause problems if that one company cannot provide all the products and solutions needed for a job.

Information Sharing
The BACnet interface allows the Prodigy Master units to share information with the building automation system. This allows for more intelligent control of the entire building automation system. The values that can be shared are room temperature, room set point, room load and many more. The values are passed through the MS/TP network as analog variables.

Connection
To allow fast and easy field connection the network uses standard RJ-45 jacks. No tools are needed to hook up the network connection; it is as easy as plugging in a laptop computer.
Also included with each Prodigy Master Unit is a 35 foot shielded plenum rated cable. This reduces field installation costs greatly since cables do not need to be sourced and assembled on site.

Addressing
Addresses are set at the Prodigy Master junction bracket using field settable DIP switches. Status LED’s show network receive and transmit activity to aid in troubleshooting. On power up the address code is blinked out on the red receive LED to confirm the address has been set correctly.

MS/TP Network Termination
In order to properly terminate an MS/TP network there must be a terminator (typically a 120 ohm resistor) at the start and end of the network. The terminators help reduce reflections on the network and aid in creating a solid and stable network.
Each Prodigy Master has a terminator built in and it can be enabled by clicking a DIP switch. This saves wiring cost and reduces complexity in the field.
The Prodigy Series is constantly evolving to include new features. Please contact Price for more information.
