Emax II operation manual

Connections
CLOCK OUT CONNECTION
The Clock Out jack allows the Emax II to be the master clock and drive non-MIDI
sequencers and drum machines at a rate of 24 pulses-per-quarter note. This is a 5 volt
pulse which is about 6 milliseconds wide.
SCSI CONNECTION
The 25-pin connector on the rear of your Emax II is a SCSI port (pronounced scuzzy),
which stands for Small Computer Systems Interface. SCSI is an ultra high-speed parallel
port, normally used to connect external hard disk drives. Up to 7 external devices can
be connected the the SCSI port. Each device on the SCSI bus must have its own unique
ID number so that Emax II can distinguish it from the other devices. If you have an
internal hard disk, it will be assigned ID #1. The floppy drive is assigned ID #0. If there
are two devices on the SCSI bus with the same ID number, a SCSI error will result.
Consult the operation manual of your external storage device for information on
changing the ID number.
●
Always use quality SCSI cables which are as short as practical (total length <12 ft).
●
Tighten the thumbscrews on the jacks to ensure good electrical connection.
●
Power up external SCSI devices
before
the Emax II.
●
All SCSI devices on the bus
must
be turned on.
RS-422 CONNECTION
The RS-422 connector is a high-speed
serial
communication port which allows data to be
transferred to and from an external computer at a high rate (500K baud). The connection
cable to the external computer will generally be supplied with a software package (such
as Sound Designer by Digidesign) and will not usually be available from your music
dealer.
110V/220 V SELECTOR
The 110V/220V selector allows the Emax II to be used in either 110 volt or 220 volt
environments at either 50 Hz or 60 Hz. In the USA ,110 volts is the standard. To change
the voltage setting, first UNPLUG the unit; then use a flat blade screwdriver to change
the setting.
WARNING:
Operating Emax II at the wrong setting may seriously damage
the unit.
AC POWER CONNECTION and FUSE
The AC power connector is how the Emax II gets power (obviously). The fuse receptacle
is not as obvious. It is located directly over the power receptacle. Before changing or
checking a fuse, UNPLUG the power cord. To remove the fuse holder, squeeze the two
tabs located on either side of the fuse holder together. The fuse holder will now pop out
with it’s two fuses. The Emax II uses (2) 1 amp, 250 volt fast-blo mini-fuses. The Emax
II should not normally blow fuses. If a fuse that has been replaced blows again, do not
attempt another replacement. Have the unit serviced!

Warning: All SCSI
devices connected to
the SCSI bus must be
turned on , or Emax II will
not boot.
