Reminders of installing DKC-900 Upgrade Kit

I've installed over a dozen DKC-900's, here are some refreshers that are paramount to know whenever you install a DKC-900 Unit. The installation process takes 2 hours, plus, allow for 1 hour to demonstrate how it works to the customer.

Remember, the DKC-900 lets customers have intuitive access to Yamaha piano radio services and other premium piano performances through Disklavier TV, Smart feature (at bottom of built-in songs), and "Music Shop" purchases.

Upgrades are ONLY possible with an existing Mark IV or E3 player system. Older systems like the Mark III Yamaha Disklavier Pianos cannot be upgraded (unless you are willing to find a DKC-800 or DKC-850, which are no longer produced).

*It is important to access the official Yamaha DKC-900 Installation Manual for all electrical safety methods, protection for the piano & technician, and thorough details to properly install this Yamaha product.

The intended use of this information is for quick-reference purposes.*

Material Must-Haves (Not included in the DKC-900 Upgrade kit!)

  • Usb Thumb Drive (Necessary to upgrade to version 5.21 once installed)

  • Customer-owned Usb Thumb Drive/Hard Drive (To extract all customer music/files from current system)

  • Extra screws, clips, fasteners (for wires/cabling)

  • Access to Installation Manual

  • Overview of DKC-900 Product Features

Important things to NEVER skip BEFORE installation

  • Check that it turns on, plays notes AND pedals function

  • Check that the audio backing of the silent system works when playing the keys of the piano in silent mode

  • Check that the speakers/background music works

  • Check for obvious damage to the piano and bring to the customers attention before beginning work (if any)

*Make careful note of ALL 4 observations. Failure to do so may be time costly, plus, it is the technician who is responsible for the correct information.

Before you start...

Opening the manual

The official DKC-900 installation manual is separated into 3 sections and it will save confusion to know whether you are upgrading from an E3 or a Mark IV to begin with. As well as whether or not it's an upright/grand, you should call a technician if you can't tell the difference!

Sections of the Installation Manual

  1. From a Grand Piano (GP) with an "E3"

  2. From a Grand Piano (GP) with a "Mark IV"

  3. From an Upright Piano (UP) with an "E3"

For the sake of demonstration I will be discussing the 2nd option upgrade from a Grand Piano (GP) with a “Mark IV.”

Start: DKC-900 Installation (2-3 hours)

Backup of Data

Generally, customers who upgrade to a DKC-900 know enough to have prepared backups of their own music before the technician arrives.

The only thing that is necessary of you is that you ask whether the customer has properly backed up the data BEFORE you arrive.

This will save time and allow you to be properly prepared for the appointment.

*If the customer has not backed up the data and needs help, it is best to reference this process in the installation manual and come equipped with the necessary USB flash memory with sufficient storage to successfully offload the music. Test the success of this step by accessing the music from a laptop with the USB inserted.

Operation Check

To repeat what was highlighted above, it is crucial to run through these steps to avoid the consequences of improper installation, innocent mistakes, and/or lack of due diligence.

  • Check that it turns on, plays notes AND pedals function

  • Check that the audio playback of the silent system works when playing the keys of the piano in silent mode

  • Check that the speakers/background music works

*Again, make careful note of ALL 3 observations. Failure to do so may be time costly, plus, it is the technician who is responsible for the correct information.

Removal of parts (KEEP power supply box)

DKC900 Mark IV old parts

Parts:

  • I/O Center Removal or Unplugged; remove all cables connected to this unit.

  • Removal of the Media Center; remove all cables connected to this unit.

Yamaha DKC900 Removal Diagram

Common Cables:

  • Remove old RCA cables that plug in to speakers

  • Remove old S/P-DIF cables (blue & green)

  • Remove old D-sub cable (thickest cable)

  • Reuse LAN (internet) cable

Many cables attached to additional musical hardware equipment/accessories that are not native Yamaha products may be referenced extensively in the Installation Manual.

The power cable can be clipped into place ("fixed") to the side of the rim, so full removal is not necessary.

*Are you in Europe? If so, you may need to use a pre-existing D-sub cable that attaches to the "option" on the CC-unit:

"The way to tell is to quickly drop down the E3 PSU and look for the white ERP sticker. If you find one then you MUST use the original 15 pin cable and attach it to the 'OPTION' port on the 900 I/O box. The system will not work without this second cable connected. This will NEVER occur on a MK4 because by definition they are too old for ERP. Also, in the USA you will never encounter the issue. It's only in Europe...."

Installation of New Parts

  • New Switch Box (left side of the keyboard)

  • CC Unit (Control Center Unit)

  • Plug in UD-WL01 to rear of Switch Box

Please be sure that the parts are installed in correct position in the example below for an elegant look. Also note that 392mm is roughly where the CC Unit belongs from the bass side of the piano, use common sense to fit in optimal position. (Roughly behind the Trapwork)

  • D-sub Cable (Switch box to CC Unit)

  • S/P-DIF (Green & Blue Cables) - attach/reuse old "Ferrite core" to CSP side

  • DC Cable (Power Cable for CC Unit)

  • USB cable (Switch Box to CC Unit)

  • Earth Cable (Grounded to screws

Power Up

  1. Be sure UDWL-01 is inserted to the rear of the switch box

  2. Turn on Power supply after plugging-in

  3. Connect DC power adapter to outlet

  4. Power on Switch Box

Powering up in this order is for best practices purposes.

Firmware Update: Version 5.21 and Calibration

Currently, the Version 5.21 firmware may be installed “over the air” after connecting the DKC-900 to the internet.

This is why it is crucial to have a USB device with the 5.21 firmware version readily available. (Password distributed to authorized technicians only; contact Yamaha for access).

Lastly, be sure to calibrate the piano and troubleshoot any errors that appear during calibration.

A few things to check are:

  • Excess friction

  • Sluggish solenoids

  • Dirty greyscales

  • Proper model setting

  • Misfiring solenoid (rare; replace key drive board)

The actual artists have instrument exclusive content on the piano, now through the seamless compatibility of their favorite mobile device!

Final Remarks

This guide should act as a "refresher" so that we don't miss anything during routine installations and that we avoid the most frequent and sometimes silly mistakes that warrant a call-back.

The “Brief Refreshers” and “8-Step Installation Guide” should help customers have a consistent experience with their new DKC-900's and give peace of mind to the technician in preparation for installing this Yamaha product.
