Installing Kurzweil K2600 ROM Options
Installing ROM Option Cards (Keyboard or Rack-Mount Models)
Daughter Board Installation for Rack-Mount Models
Warning:
The K2600 and ROM options are sensitive to static electricity. Before handling the
daughter board, please follow the instructions on page 4 for protection from static electricity.
1. Unplug all external wires, cables, and connectors from the K2600R and turn it upside
down.
2. Locate the access panel on the bottom side of the unit. Using a #2 Phillips screwdriver,
remove the six screws attaching the access panel. Set the access panel and screws aside for
reassembly.
3. Remove the adhesive strip backing from the
thin
piece of foam supplied in the RMB-26 kit
(the thick piece is for installation in keyboard models, and you won’t need it). Attach the
foam over the cross-hatched area on the access panel.
4. Locate Connector J809 (labeled ROM EXP) and the three standoffs (white plastic pins that
stick straight up) on the CPU board. See Figure 1.
5. Align the ROM option daughter board so that Connector J1201 on the daughter board
lines up with Connector J809 on the CPU board. The three holes in the daughter board
should line up with the standoffs on the CPU board.
6. Press down on the ROM Option Daughter Board to attach it to the connector and
standoffs on the CPU board. The board will snap into place on the three standoffs.
7. Proceed with the following instructions for installing ROM option cards.
Installing ROM Option Cards
(Keyboard or Rack-Mount Models)
If you haven’t already installed the ROM option daughter board (RMB-26), turn to the section
called
Installing the Daughter Board
(page 4), and follow those instructions. Then return here to
proceed with the installation of your ROM option(s).
Warning:
The K2600 and ROM options are sensitive to static electricity. Before handling any
option card, please follow the instructions on page 4 for protection from static electricity.
1. On the daughter board, locate the connector for the ROM option card you are installing.
You can install either ROM 4 (Vintage EPs) or ROM 5 (General MIDI) in the ROM 4 slot.
As shown in Figure 2, the connectors are labeled as follows:
• ORCHESTRAL ROM BLOCK A
• CONTEMPORARY ROM BLOCK B
• ROM 3
• ROM 4
Notice that the connectors for the Orchestral ROM option and the Contemporary ROM
option are spaced farther apart than those for ROM 3 and ROM 4. That’s because the cards
for the Orchestral ROM option and the Contemporary ROM option are rectangular, while
the cards for ROM 3, ROM 4, and ROM 5 are smaller, and square in shape.
Caution
: The option cards are “keyed” so that you can’t insert an option card into the wrong
pair of connectors—you couldn’t accidentally put the Orchestral ROM option into the
connectors for the Contemporary ROM option, for example. It
is
possible, however, to insert an
option card with the wrong orientation, which could damage the card. To prevent this, both the
daughter board and the option cards are marked with arrows. Make sure that the arrow on each
option card points in the same direction as the corresponding arrow on the daughter board.
