Manufacturer: QSI Solutions


Summary: QSI Solutions (QSIS) was the consumer products affiliate of QS Industries (QSI) of Portland, Oregon. QSI was and continues to be the industry’s premier pioneer of DCC sound and control technology; as such it is the owner of more DCC patents than all other manufacturers of DCC sound components combined.QSI Solutions (QSIS) partnered with QS Industries (QSI) to develop and manufacture its large-scale decoders the Revolution, and later the Titan. QSI also distributes and provides technical support services for the full range of QS Industries (QSI) products, from the Q1a decoders factory-installed as OEM equipment in many models, to today’s Titan™decoders, the most advanced and powerfully realistic aftermarket model railroad sound and control decoders in the industry.

Description

In 2013 QSI became independent of American Hobby Distributors. From Model Retailer:

QSI Solutions, a subdivision of American Hobby Distributors, has been reformed as a stand-alone company.

American Hobby Distributors owner Tony Parisi announced the change Sept. 25. QSI Solutions will now rest under the ownership of longtime manager and product developer Joshua Shedaker, according to a release from the company.

Subsequently QSIS has gone dormant, and the Large-Scale decoders are only available on the secondary market.

Current Status

The current status of QSIS is unknown at this time.

The QSIS website website is still partially functional, but some sound files are missing things such as instruction manuals, etc. You can go to the groups.io forum and get files and software there: [1]

Q S Industries

QS Industries has a website at QS Industries which offers various items such as programmers and Titan multifunction decoders. Manuals and sound files are also available for download.

Contacting QSIndustries

The easiest way to contact QS Industries is via the QSI Email list on Groups.IO, or direct email. The website and telephone numbers are not monitored at this time. [1]

Quantum Programmer

QSI had their own computer interface, the Quantum Programmer which connected to the computer via USB.

Multifunction Decoders

Troubleshooting

QSI multifunction decoders can enter a sleep mode. If this happens the decoder may be unresponsive.

To exit this mode try pressing the F6 key twice in rapid succession. It may take several attempts before this works.

Programming

In Operations Mode Programming, there are a couple of issues:

  1. The locomotive sound must not be muted;
  2. Verbal Acknowledgement, CV62, must be disabled by writing a 0 to that CV.

These parameters are also true when consisting locomotives with QSI multifunction decoders.

Multifunction Decoder Reset

QSI multifunction decoders can be reset by the normal methods, but will sometimes require a hard reset.

To do a Hard Reset (https://groups.io/g/jmriusers/message/192579):

  1. Place the locomotive on an independent, separate length of track. There should be nothing connected to it, electrically or physically
  2. Gain physical access to the reed switch
    1. This will require removing a hatch, the body of the locomotive or the tender
  3. Short the reed switch by connecting a jumper across it
  4. Place a 9V battery across the rails
  5. Disconnect the jumper across the reed switch

The locomotive's voice prompt should state RESET. It may take several attempts for this process to succeed.

QSI Solutions FAQs

Q: QSI Decoder Resets on Startup

If a QSI multifunction Decoder resets upon startup, the reed switch used for this purpose has failed and is in a closed position.

Remove the reed switch and the decoder should work as normal.

Q: Muting a QSI Decoder

Muting a QSI decoder requires several steps, using function F9 on the throttle.

Press F9 twice to sequentially enter the following modes:'"`UNIQ--ref-000000C4-QINU`"'

  1. Disconnect: Locomotive switches to Neutral. As in the prototype, where the traction motors are disconnected from their power source, the locomotive will not move with the prime mover idling. Changing the throttle causes a change in engine RPMs, but your model will not move. Diesels will switch to Low Idle sounds, steam locomotives and electric motors, they will appear to be completely inactive except for cab and number Board lighting, air compressor and blower / fan sounds.
  2. Standby Mode:
    1. All lights go out except number boards; engine goes to low idle speed. In Standby, the locomotive will not respond to the throttle or most function keys.'"`UNIQ--ref-000000C5-QINU`"'
    2. The three exceptions are
      1. F6, Start Up Function Key
      2. F8, Mute Key
      3. F10. Status Key
  3. Total Shutdown
    1. Various sounds will be heard, such as the handbrakes being applied, and the engine will shut down. The locomotive will be silent at this point. '"`UNIQ--ref-000000C6-QINU`"'

Double pressing F6 at any time will return the multifunction decoder to normal operation.

Note: When in total shutdown the locomotive will be taken offline. It will remember this state next time the layout is powered up. This is also true for Disconnect and Standby modes.

When using DCC, power is on the rails at all times, and the multifunction decoder will sit idle awaiting a command. In this state they do not require much power, especially if the audio is muted.

Modes such as neutral confuse operators at times. The decoder responds but the locomotive will not move until the decoder receives an instruction to change to normal mode. If this happens, consult the manual for details. Some decoders may have a "brake" that must be released first.

Pressing F10 while in Neutral provides audio prompts, reporting its current Primary or Extended Address, Consist address (if part of a consist)'"`UNIQ--ref-000000C7-QINU`"' and Disconnect, Standby or Shutdown modes.

When in motion, F10 reports locomotive speed. This can be configured to report BEMF and PWM values too. '"`UNIQ--ref-000000C8-QINU`"'

Q: QSI Throttle Control Modes

  • Standard Throttle Control (STC): Percentage of full power applied to the motor is related to the throttle setting (speed step). As power to the motor is constant for a given throttle setting, the speed varies depending on the load. The locomotive may stall at low speeds from minor gear binding, turnouts, and curves.
  • Calibrated Speed Control (CSC)'"`UNIQ--ref-000000D8-QINU`"': Power applied to the motor is varied to maintain a constant speed regardless of load conditions. The throttle setting (using 128 speed steps specifies the locomotive’s speed in 1 smph (scale miles per hour) increments. If the throttle is set at 35, the locomotive attempts to maintain 35 smph on level track, uphill and downhill. If locomotives in a consist differ slightly in speed calibration, some do all the work while the others are pulled along.
  • Load Compensated BEMF Speed Control (BEMFSC)'"`UNIQ--ref-000000D9-QINU`"': Under BEMFSC, each speed step corresponds to a target BEMF value. The decoder adjusts the power applied to the motor so the locomotive’s measured BEMF matches the target BEMF.
  • Regulated Throttle Control (RTC): RTC combines the best of STC and Speed Control. It is the preferred method when consisting Quantum locomotives together as it automatically equalizes power between locomotives. Like Speed Control, RTC allows locomotive operation at very slow speeds without concern that it may stop abruptly from minor impediments, such as misaligned track joints, tight curves, or rough switches. RTC operates your locomotive as though it is a large mass; the locomotive will resist changes in speed once moving and resists starting up quickly when at rest.

Default is Regulated Throttle Control. See the Quantum DCC Reference manual for more detail. CV = 56.4
