Manual: Steeldrive II Motor Unit
Dear customer,
congratulations for purchasing a Steeldrive II
(SD II) motor focuser. This manual describes ins-
tallation and operation of the Controller.
In case of questions or problems, please consult the
FAQ on our website or contact your dealer or us.
www.baader-planetarium.com/en/steeldrive2
The Baader Steeldrive II motor focuser consists
of the motor unit and the controller. Both units
are also available seperately. You always
need one controller to operate one
motor unit. But you can use one cont-
roller with several motor units one at a
time – you only need to plug it into
the motor unit which you want to
use.
Steeldrive II Control Unit – Highlights # 2957260
• Controls the temperature compensating Steeldrive II focusing motor for
Baader Steeltrack®(Classic and Diamond) focusers and optionally many
other focusers
• AUX port for precise temperature control e. g. of dew shield heaters, opti-
cal lters or instruments with a precision of +/-0.1 degree
• Intuitive handling: The back-illuminated hand control makes fast switching
between normal speed, jogging and single step mode easy
• 12V power supply included, as well as 3 m USB cable to connect to a PC
• Incl. revised, powerful SteelGo II Software (as download)
• Made in Germany: The housing is CNC-milled from Aluminium in our fac-
tory. The electronical boards are made by a German company according
to our specications.

5. Manual Operation with
the Steeldrive II Controller
As soon as you connect the SD II Controller (hand-
control) to the power supply included in the scope of
delivery, it will start up, and the backlight illumination
will turn on. With the keypad of the controller, you can
use the following functions even without a computer.
5.1 Setting the Zero Position (Zeroing)
Option 1: Manual homing without Homing-Sensor
1. Disconnect the SD II Controller from the power supply. Move the focuser to
the innermost position with the ne focuser
2. Switch the SD II Controller on by connecting it to the power supply.
3. Press SET once; LED 2 will light up.
4. Push and hold IN for three seconds. The current position will be saved
as zero position, and the controller will return to normal mode.
Please note: You need the SteelGo II software to set which mode is used. Alternatively,
you can use the Override-Limits-Mode.
3. Installation
of the Controller
1. Connect SD II Motor Unit
and SD II Controller with
the CAT 7 RJ45-cable
(included in the scope
of delivery of the SDII
Motor Unit).
2. Connect temperature sensor, USB-
cable or AUX-devices, if desired.
3. Finally, connect the power supply.
4. Carefully bind all cables for the
remote operation together with the
included Velcro tape(s) 5, so that
the connector of the RJ45-cable
can keep the strain away from
the other cables.
4. Steeldrive II: Three Operation Modes
1. Manual: The Steeldrive II focuser is operated
completely with the keys on the controller. To
do so, please take a look on the keys and their
functions in the next chapter.
2. ASCOM: You can operate the SD II through the
ASCOM-driver with common observatory
control software.
3. SteelGo II: You can use the SteelGo II soft-
ware on a PC which is connected to the
Controller. This way, you can easily
use all the functions of your SD II. All
options of SteelGo II are described in
a seperate manual.
Both operation modes "ASCOM" and
"SteelGo II" are described in detail in the
seperate SteelGo II manual.

5.3 Focusing with the Steeldrive II
The controller features three speeds. You can easily switch between them:
• Normal Mode: Standard mode, is activated automatically once the cont-
roller is connected to the power supply. Press and hold the IN or OUT
key to move the focuser continously in- or outwards (as long as the
key is held).
• Jogging Mode: Is activated by pressing the key JOG once. LED 1
lights up. Once the Jogging-Mode is activated, a single push on the IN
or OUT key moves the focuser for a predetermined number of steps
inwards or outwards (by default, this corresponds to ca. 0.05 mm with a
Baader Diamond Steeltrack®focuser).
Please note: The amount of steps can be changed in the SteelGo II Software.
• Single Step Mode: Is activated by pushing the SET button while the
Jogging Mode is already active (LED 1 is on for Jogging Mode). LED 1
and 2 light up. Once the Single Step Mode is activated, the focuser is
moved for one step (0.0027 mm – 2.7μ – with a Baader Diamond Steelt-
rack®focuser) inwards or outwards each time you push the IN or OUT
key. Press SET again to return to the Jogging-Mode; press JOG
to return to the Normal Mode.
Please note: The single steps can also be configurated in the SteelGo II software.
This way, you can also use two Speed-Modes with different steps, according to
the requirements of your telescope.
Recommended way of focusing:
1. Use the Normal Mode to move the focuser near the focus point
2. Use the Jogging Mode to move the focuser to the focus point as close as
the step width of one jogging step
3. If necessary, use the Single Step Mode to achieve perfect focus.
4. Save the focus point to access it later (see 5.4)
5.4 Saving a Focus Position
Once you have found the focus position, you can save it as a favorite. Do the
following steps in normal mode (LED 1 and 2 are off):
1. Push SET to switch into the settings mode (LED 2 is om)
2. Push and hold JOG for three seconds until LED 2 is off. Now, the current
position is saved as favorite.
Option 2: Manual Homing with the Homing-Sensor
1. Perform steps 1 and 2 as in option 1
2. Move the focuser with OUT aproximately 1 to 2 cm outwards
3. Then move the focuser by pushing IN until the homing-sensor responds
and the focuser automatically stops.
The current position is then saved automatically as "zero position".
Option 3: Automatic Homing with the Homing-Sensor
1. Connect the SD II Controller with the USB port of your computer
2. Activate the option "Use-Endstop" (Settings » Motor Settings) in the Steel-
Go II software.
This option has to be set only once and is stored in the controller. So,
you can use the automatic homing even if the SD II is not connected to
a computer (see 3b).
3. a) Automatic Homing with SteelGo II software:
Click "Zero" in the software. Now, the focuser will move inwards until
the homing-sensor is activated, and the zero-position is saved auto-
matically.
b) Automatic Homing with Steeldrive II Controller:
• Press SET once, LED 2 lights up.
• Press and hold IN for three seconds. Now, the focuser will
move inwards until the homing-sensor is activated, and the zero-
position is saved automatically. Then, the controller returns to
normal mode.
5.2 Setting the outer limit
The outer position of the focuser depends on the model of the focuser and the
telescope. By default, the controller is set to the maximum length of the BDS-
SC-focuser (30 mm). If the focuser shall mover further than to the current limit,
you need to activate the Override-Limits-Mode rst (see 5.7), otherwise you
can't move it to the new outer limit.
1. Move the focuser with OUT to the outermost position to which it shall
move later. If necessary, activate the Override-Limits-Mode.
2. Press SET once, LED 2 lights up.
3. Press and hold OUT for three seconds, until LED 2 turns off again.
Now, the new value for the outer limit is saved, and the Steeldrive II returns to
the normal mode (all LEDs are off).

5.5 Returning to a saved Focus Position
If you are in normal mode (LED 1 and 2 are off):
1. Push and hold JOG for three seconds. Now, the focuser moves to the
stored position.
Over time, small errors caused by slippage may add up. We recommend that
you move the focuser to the zero position dened by the homing sensor before
you move it to a stored position.
5.6 Activating and Deactivating the Temperature Compensation
The automatic temperature compensation must be congurated through the
SteelGo II sonftware and a PC. It can only be turned on or off with the key pad
of the controller.
• Activate: When in normal mode (all LEDs are off), push and hold SET
for three seconds. Now, LED 2 is blinking slowly.
• Deactivate: Once the temperature compensation is active (LED 2 is
blinking slowly) and you are in normal mode, you can turn it off by pushing
and holding SET for three seconds. Then, LED 2 will go off.
5.7 Override-Limits-Mode
If necessary, you can ignore the limits which are set in the Steeldrive II. This is
e.g. useful if you want to set a new outer limit, which is farther outwards than
the current one.
1. When in normal mode, push SET once until LED 2 lights up.
2. Now hold SET for three seconds, until LED 2 ashes fast.
3. Now you can move the focuser with IN and OUT to a new limit.
4. To leave the override-limits-mode, hold SET for three seconds to return
to normal mode, until LED 2 goes out.
If desired, you can save the new outer limit (see 5.2).
