Welcome to the Opus-Two family! The Opus-Two Instrument Control System is one of the most
versatile, flexible, and certainly one of the fastest control systems available. Before you do
anything, please take the time to read this entire document. Many of your initial questions will
be answered in these pages.
The control system in this box is a bit like a jig-saw puzzle, but unlike a jigsaw puzzle, this one
has piece by piece directions. If this is your first control system, we strongly suggest getting the
console up and running first before even starting to build chamber panels, this will provide all
the knowledge you need to work in the chambers.
You will not have a "programming cable" per se with this control system. The controllers use
standard micro-USB cables (the same as an android smart phone charger).
Take the time to familiarize yourself with the terminal interface in the console controller. This
is a self-exploration that should be done at any time. By simply plugging into that controller
with a USB cable, it will power up and you can immediately connect to it with a computer
(instructions are contained within this book).
An online video series will be available at
www.opustwoics.com
starting in the summer of 2020
that will expand upon the information found in this guide.

- Page 1 Welcome to the Opus-Two family! The Opus-Two Instrument Control System is one of the most versatile, flexible, and certainly one of the fastest control systems available. Before you do anything, please take the time to read this entire document. Many of your initial questions will be answered in these pages.
- Page 2 Laying Out The Card Chain The controllers and I/O cards get plugged together to make chains. Refer to your documentation to know how long to make the console chain. The console will get one controller and the appropriate number of I/O cards.
- Page 3 Locate and Install The Display The display will get its “control buttons” mounted around it. These are typically engraved pistons with no lamps. If Walker pistons are used and they are being plugged into the display board, negative output is required for these particular pistons.
- Page 4 On the controller card, there are only two connection points (polarity is silkscreened on the card). For IO64-LED cards (green PCB): On the I/O cards, there are four power terminals: VP/VPF/VN/VN. The two VN terminals are linked and therefore interchangeable ground/common wires.
- Page 5 We suggest that any common (return) wires from a load (such as coils or chest magnets) should be fused in 6A groups per NEC. This generally means that no more than 12 stop action coils per fuse. Switches providing input back to the I/O card can have more on a single fuse, but never put more on a fuse than you would want to stop working if the fuse would blow.
- Page 6 (stops moving for no reason, etc). This is not specific to Opus-Two, and many other manufacturers have subtle problems with switch-mode power supplies. If you do use a switch mode power supply, Opus-Two has built in software to check for a “rough power down” sequence.
- Page 7 Connecting Console to Chambers If your control system is so small that there is only one controller card, this section doesn’t apply to you. Otherwise, on each chamber controller card is a green 3 pin connector. Connecting the 3 pin connector in the chamber to one of the 3 pin connectors in the console per the wiring diagrams.
- Page 8 Checking the Basics (in the console) Each of these steps is provided in intentional sequence, do not jump ahead or else you could skip something important that needs to be verified. Remember that before even touching the “digital” side of the control system, you can use the LEDs on the cards to verify individual items (such as key contacts, stop sense lines, etc.) 1) Does the display show “Memory Level”...
