Single-Control
Hand Unit for JMI MOTOFOCUS, MOTODEC
and Focusers
The single-control (controls one motor) linear
voltage control (LVC)
hand unit includes two forward and reverse
buttons (red) and a two-position slow-speed switch (black). The slow-speed switch
adjusts from high (left) to low (right). The system automatically
changes from slow speed to fast speed when one of the forward or reverse buttons
are held down for two seconds or more. This effectively gives the hand unit
three speeds — very slow (1), slow (1.5 times faster) and very
fast (5 times faster). The system includes a 1/8" jack, quick-stop braking and a 9-volt alkaline battery.
It can control MOTOFOCUS, MOTODEC,
EV, NGF
and RCF motors. This hand unit gives the best
control of any system ever manufactured by JMI.
|
NOTE |
The
hand unit has two switch-adjustable slow speeds
(left for high slow and right for low slow) which normally ramp up to a fast speed after two seconds. Placing the slow-speed switch
between the two normal positions (high and low) will cause the speed
selection to be overridden and the motor will run at very fast speed (5)
at all times. In rare cases, the low slow speed will not drive the
motor. In that case, use the high slow speed only.

Dual-Control
Hand Unit for JMI MOTOFOCUS, MOTODEC
and Focusers
The dual-control (controls two motors) linear
voltage control (LVC) hand unit includes the same functionality found in the
single-control hand unit (forward and reverse buttons, a two-position slow-speed
switch, quick-stop braking
and a 9-volt alkaline battery). It also includes two
1/8" output jacks and a switch to select the active jack. It is
designed to easily control two motors, such as MOTOFOCUS and
MOTODEC,
from one hand unit.

What is
a Hand Unit?
Our standard motor-control Hand Units or Hand Controls
have forward and reverse buttons that operate all of our MOTOFOCUS and

Every hand unit includes an electronic brake for instant stopping when you
release the button. |
Customer
Comments
"My new single-control
hand unit is much better than the original. Everyone should
upgrade." (T. H.)
"... BTW, I did
tell the guys at the RTMC table that if they were to come to my house and shout
JMI, most
of my astronomy stuff would come to attention and salute! ..."
