MODEL NUMBER DESIGNATION AND SYSTEM CONFIGURATIONS
The model number system is used for product identification. It includes a
basic model series number which is followed by a virgute (/) apd then a six
digit number and finally a three digit dash number. The model number is
used to code and identify a particular combination of .options used in a
given product line •. This number is printed on the serial tag and is
located on one of the rear surfaces. Those digits to the left are the basic
model series of the product line (REMEX 40, 20, 48, 24) The six digits to
the right· and the three dash dash numbers give the top assembly number of
the product. The three digit dash number is unique for any particular com-
bination of options and configurations used in the basic assembly. Tables
1-2 through 1-5 list the' various model numbers and a description of the
system configurations for the REMEX 40, 20, 48 and 24, respectively.
Consult the various drive manuals for the differences in the drives.

INSTALLATION AND Ir..TTERFACE
2.1
UNPACKING
To provide the most protection during transit, specially designed and rein-
forced packing cartons are used to ship the REMEX System. When removing the
system from the carton, lift the system with both hands under it. Never lift
or attempt to carry the system by any covers, drive doors or other delicate
parts. Carefully inspect the unit for any apparent damage as soon as it is
removed from the carton. In the event the equipment has been damaged as a
result of shipping, the carrier and REMEX must be notified as soon as possible.
It is important that during unpacking, installation
and operation that the read/write' heads do not come
in contact with stray magnetic "fields.
2.2
MOUNTING
The system is desi~ed to operate in a horizontal mode; however, the system
will operate standing on either side. Mounting hardware and brackets are'
provided in the kit of parts. The bracket mounting is shown in Figure 1-2.
It is important that the air flow requirements given in Section 1.2 be
followed during mounting and operation and that no obstruction occurs in the
air flow path.
2.3 INITIAL ADJUSTMENTS
"Each system has been accurately adjusted and aligned before leaving the
factory. No adjustment or calibration should be required prior to install-
ation or use. Drive A has the line terminator removed and a shorting plug
has been removed from U-U and installed at u-4 on the circuit card. This
gives a Unit Ready on pin 4 of the output connector. Drive B retains the
line terminator and has the shorting plug removed from U-U and installed
at U-6. This gives a Unit Ready output on pin 6 of the output connector.
In addition, drive A has a shorting plug on DS1 which selects it as drive
1 or pin 26 and drive B has its shorting plug on DS2 which selects it as
drive 2on pin 28. See Sections 2and 3 of the drive manual for interface
signal details.

2.4 POWER AND SYSTEM CONNECTIONS
AC power is applied to FLIOI at the rear of the system via the supplied power
cord. See Figure 2-1 for rear view. It is also necessary to install the fuse
FlOl and fuse carrier supplied in the kit of parts. The power switch SlOl is
also located at the rear of the unit and must be placed in the ON position
before operating the system. REMEX 20 and 40 units are provided with a daisy
chained 50-wire flat ribbon cable and connector. REMEX 24 and 48 units are
provided with a 34-wire flat ribbon cable and connector. A connector is also
provided (REMEX 24 and 48 only) for connection of an expansion chassis (if
used). Refer to Section 2.4 in the drive manuals for the signal interface
descriptions for the particular drive being used.
~J
Always consult the serial number tag for proper
voltage and frequency to be used. Failure to do so
could result in damage to the unit. It is not
recommended that the power supply or drives be
changed in the field to accept a voltage or
frequency other than that listed on the serial
number tag. See Tables 1-2 through 1-5 for
model number explatations and the required
voltage and frequency.

OPERATING INSTRUCTIONS
3.1
OPERATOR CONTROLS
The system operates under control of acomputer or microprocessor except for
loading and unloading diskettes. Apower ON-OFF switch is provided on the
rear panel. An indicator in the door opening button indicates when a drive
is busy. The button is also mechanically interlocked to prevent opening
of the door when the drive is s,elected. Drive A is defined as the drive on
the operator's left and,drive B is on the right.
3.2 DRIVE OPERATION
The loading and unloading of diskettes and the various modes of operation
for each of the drives is contained in Section ,3 'of the particular drive
manual.
