Precautions When Installing
the Optional Boards
Remember the following precautions and install the
boards properly.
• To avoid using the wrong parts and making mistakes
during installation, follow the steps as written.
• Before starting installation, be sure that you have a
Phillips screwdriver at hand.
• All necessary screws are provided with the optional
boards or are installed on the EX5/5R/7. Therefore
do not use any screws other than what are installed
on the EX5/5R/7 or come with the optional board.
Screws that are not the correct size may cause
damage or result in a malfunction.
• Be careful not to misplace any of the screws since all
of them are used.
• The screw should secure the board so it is
completely stable and does not move in any way.
• Handle the boards with care. Dropping or subjecting
the board to any kind of shock may cause damage or
result in a malfunction.
• When moving a cable, be careful not to let it catch
on the circuit board. Forcing the cable in anyway
may cut the cable, cause damage, or result in a
malfunction.
• Do not touch the exposed metal parts in the circuit
board. Touching these parts may result in a faulty
contact.
• When connecting cables or directly inserting a board
(DRAM SIMM for example), make sure that you
check that they are connected or inserted properly.
Improperly inserted cables and boards may cause
faulty contacts and an electrical short circuit which
may cause damage or result in a malfunction.
• Be careful of static electricity. There are times when
static electricity affects the IC chips on the main
board. Before you lift the optional board, to reduce
the possibility of static electricity, touch the metal
parts other than the painted area or a ground wire
on the devices that are grounded.
A variety of optional boards/memories sold separately
let you expand the functions of your EX5/5R/7. The
following five types of boards/memories can be used
with the EX5/5R/7.
● EXIDO1 (Individual Output Board)
The EXIDO1 increases the number of assignable audio
output jacks. The EX5/5R comes with four outputs,
L/MONO, R, and Individual Output 1, 2. Installing the
board which has four Individual Outputs 3~6 brings
the total of outputs to eight. The EX7 with L/MONO
and R stereo outputs along with the Individual Out
1~4 is capable of a total of six outputs.
● EXDGO1 (Digital Output Board)
The EXDGO1 after installation provides an AES/EBU
digital out jack and a Word Clock In jack.
The EXDGO1 and EXIDO1, two boards can not be
installed at the same time.
● ASIB1 (SCSI Interface Board)
A SCSI connector can be installed in the EX5/5R/7.
This lets you connect external SCSI devices, such as
hard disk drives, ZIP, JAZZ disk drives and CD-ROM
drives. External SCSI device operations are
accomplished in the Disk mode.
● EXFLM1 (Flash Memory Board)
When the power is turned off, all the data in RAM is
lost. However, Flash memory data is not volatile and
remains recorded. When Flash memory is installed, just
like ROM, the data can be used as soon as the system is
turned on. In the EX5/5R/7, Flash memory (4MB x
2=8MB) can be used to store sample data. Also the
data can be overwritten whenever you like.
Take note that the EXFLM1 should always be used in
pairs.
● DRAM SIMM
DRAM SIMM (Single In-line Memory Module) can be
used as RAM for recording sample data. You need to
use 72-pin DRAM SIMMs (4, 8, 16, 32MB) in pairs. It
is possible to increase the 1MB of internal memory, a
maximum of 64MB to a total of 65MB. (However,
because the data is volatile, it is necessary to backup
data to floppy disk or an external SCSI device.)
Take note that DRAM SIMMs with the same memory
capacity should always be used in pairs.
