MECHANISM
ASSEMBLY
1-1.
OUTLINE
To activate the VHS system H type mechanism assembly using
mode selector II (J-6082-282-A), use connector conversion jig
(J-6090-052-A). By using the connector conversion jig, the
following operations are possible.
+ Loading and unloading action by the loading motor
* Reading of the current setting of the mode switch
+ Normal and reverse rotation of the capstan motor

ADDITION
OF POWER
SUPPLY CABLE
(Already added Mode Selector II also available)
In order to drive the capstan motor, the power +5 V and +12 V
are supplied from the Mode Selector II. Disassemble the D-SUB
connector of the Mode Selector cable, then solder the following
three places.

CHECKING
THE SOFTWARE
VERSION
Tum on the power of the mode selector II.
If the reading for the software version on the mode selector II is
not 1.10 or higher, replace the New ROM ( J-6082-314-A).

CONNECTION
BETWEEN
THE CONNECTOR
CONVERSION
JIG AND THE MODE
SELECTOR II (See Fig. 1-1)
Insert the connectors of the two 6-pin cables (one is white and the
other is black) and the 3-pin cable from the mode selector I] to
the corresponding connectors on the connector conversion jig
(J-6090-052-A).

CONNECTION
BETWEEN
THE CONNECTOR
CONVERSION
JIG AND THE H TYPE
MECHANISM
ASSEMBLY
With the power of the mode selector
II tumed off, insert the
following three connectors to the corresponding connectors on the
H type mechanism assembly.
¢ 3-pin connector for the loading motor
+ 5-pin connector for the mode switch
¢ 8-pin connector for the capstan motor
Set the speed control for the minimum
setting (fully counter-
clockwise).

OPERATION
OF THE LOADING
MOTOR
ON
THE H TYPE MECHANISM
ASSEMBLY
(1) Select the H type mechanism assembly setting on the mode
selector II .
(2) After this, procedures are the same as those for the previous
model types.
For the operating method, see pages 3 to 5 of "8 mm Video
Mechanism Manual VI (TK Mechanism) Supplement-1".
For the loading method, see page 3 of "WHS
Mechanical
Adjustment Manual IV (H Mechanism)".
1-4-2.
OPERATION
OF THE CAPSTAN
MOTOR
ON
THE H TYPE MECHANISM
ASSEMBLY
(1) For the loading motor operation under Section 1-4-1, change
the mode setting to the FF/REW mode with the mode switch.
(2) Tum the speed control gradually in clockwise direction, and
the capstan motor starts rotating. To turn the capstan motor
in desired rotating direction, change the FWD/RVS
setting
of the rotating direction switch.
1-5.
PRECAUTIONS
+ Tum the speed control only when necessary.
Otherwise, hold
the speed control tumed at fully counterclockwise direction.
If
the power of the mode selector II is turned on with the speed
control tumed in clockwise direction, +12V power fails and the
power of the mode selector II cannot be tumed on.
* Although the connector
conversion jig (J-6090-O052-A)
has
rubber feet, do not make a short circuit on the bottom surface
of the connector
conversion
jig via foreign
conductive
materials.
