HERMES 101 is a two-way serial interface that allows the full family of Omni (LT, IIe, and Pro II) to fully control the european bus Dupline. Using Dupline bus one can set a complete 230V solution for buildings of any type (residences, industries, offices, etc.) covering all functions such as on/off lights, dimmable lights with fluorescent or incadescent lamps, roller blinds, awnings, Venetian blinds, etc. HERMES 101 also returns the status of Omni units. Moreover, push buttons in switch boxes are recognized by Omni and can trigger Omni-programmed scenarios.
Important features of a solution based on Omni, HERMES 101 and Dupline are:
- The whole 230V network is controlled through Omni programming, making the whole implementation transparent to HAI installers and accessible through all remote means that HAI provides, e.g., Internet, iPhone.
- It holds conduit cost to the level of a conventional implementation and allows for the decision about going through a smart-home or conventional solution be taken even after house delivery without requiring painting or other similar type of intervention to the house. This is possible because the two wires that Dupline requires for control / status signals can be of any type, even part of a multi-wire cable. Therefore, a single conduit can be used for power and control with one flexible cable such as a stranded multi-wire one. This is a very important feature for Europe where brick is a main structural material and conduit is very costly. This paves the way for a customer to adopt an Omni-based solution for all functions of his home more easily. (This precious advantage is possible because Dupline transmits its control / status signals around a 1 kHz frequency, which is far from the first harmonics of 50 Hz powerlines and even farther from the 10 kHz low limit of industrial noise).
- The cost of HERMES 101 is more than offset to the cost of installing a Dupline network itself standalone! This sounds strange but it is true due to the fact that HERMES 101 can fully control a Dupline network through a dummy Dupline element (called modbus master module) only producing the bus signal. On the contrary, if we only had a Dupline network standalone we would need the much more expensive Dupline master generator. However, already existing Dupline networks based on the master generator G38000016 are supported, making the solution even cheaper.
- Stand-alone 230V network operation is supported. During implementation or technical service it is possible to have HERMES 101 and the Dupline network work standalone, that is without Omni, while the installer wants to reset or disconnect Omni. This way 230V network operation is not interrupted.
- Any type of push button of the european market is actually supported as the electronic part to be placed within a switch box is so tiny that it can be inserted into the smallest switch box, yet it can support four push buttons. This is also a commercially important feature as many times home automation solutions are likely to be rejected by end customers or architects due to lack of support to their preferred series of switch buttons.
- No low-voltage grounding is required for the two wires of Dupline bus. They work fine as floating wires. This is also a very strong advantage as many buildings do not provide for a low voltage grounding.
- Robust overall solution. Dupline is an industrial type network. This creates a very robust overall solution for a building, analogous to the stability and reliability of Omni. Dupline has been used on a great variety of buildings without even the smallest issue. It has successfully faced electrical noise of any type that other automation solutions fail to. Such types of electrical noise are powerline harmonics, powerline phase shift, industrial noise caused by motors, etc.
- One-day training is enough for an installer to be ready to implement Dupline solutions. Easy-to-use instruments, more or less like a pocket calculator, allow for giving addresses to all 230V parts leading to a very productive installation. On the contrary, other busses require a more prolonged training and their installation is by far more difficult.
Integration with HAI
HERMES 101 is connected to Omni LT, IIe, or Pro II through a four-wire RJ11 telephone cable. We just connect this cable to one of the serial ports of Omni and the respective OMNI serial port of HERMES 101.
Using PC Access or an Omni console we go to Setup>Installer>Expansion and set the Serial Function of the connected serial port to Centralite. We set the baud rate of the connected serial port to 9600. We go to Setup>Names>Units, name the unit numbers we are going to use and declare them as Centralite.
The whole procedure of integrating HERMES 101 with Omni LT, IIe, and Pro II is described in the User/Installation Manual.
