![]() This also serves to indicate whether the pin is energized or not. We also sell conversion kits with the correct number of chips and jumpers to make the process extremely easy.Įach pin on the card features a status LED which indicates the polarity of the pin. These can be changed to negative by us prior to shipping, or by a user in the field by following conversion instructions, which are available upon request. One card does both input and output, and the majority of cards are supplied positive input/output. The majority of cards installed in a system are the input/output cards. The PipeBus supports up to 256 controllers on one data bus (more than anyone will ever need). This means there isn’t a certain order that they have to be connected, and wire doesn’t have to be run in circles around a church just to make the organ play. The PipeBus connection to these cards is “parallel” – which means the PipeBus doesn’t have to go from card to card. It is worth noting that the controller cards in a given system are located in the places that the I/O cards are located (typically one in the console, one in each pipe chamber, etc.). ![]() All controllers intended to go in a console have A/D inputs for potentiometers on them, a DisplayBus port, and MIDI ports. Unlike other control systems that require fiber optic tools, ethernet switches, and other complicated interconnects, this is simply a pair of wires with a shield. ![]() This port is what allows Opus-Two controllers to communicate amongst one another. ![]() We remain ready and willing to provide service and support to any client who wishes to either simply get a run-of-the-mill relay up and running or create the next big new thing.Īll controllers feature one thing in common - the PipeBus port. Most of our larger organ builder clients simply buy the hardware and do their own configuration. Further, the Opus-Two systems that are installed have the potential to continue to service without being tethered to the manufacturer - a savvy client can continue to upgrade and make the changes they wish without consulting the manufacturer. Because of this flexibility, we have never told a client that we can't do something they want* and we have never told a client that they have to buy new hardware to make a requested feature work. If a radically new idea exists that isn't in the software libraries, it can be hand-coded in the configuration file. Once the configuration is built, the system simply works. These features are extremely easy to implement with Opus-Two, and very difficult to implement with any other control system. What sets control systems apart is when someone needs something that's a little different - if an expression matrix needs to be stored on a combination action, if page turn needs to be integrated into the control system, if the client wants a variety of expression couplers or flexible manual couplers, if a few flexible stops are needed, or even if the client wants tremolos to be adjustable and savable on each piston. Pistons, reversibles, crescendos, sforzandos, and more are fairly common in the industry. Those features are common to all control systems and generally work the same. The vast majority of organs use the same features over and over again.
