motor driver board. Follow safety precautions when making these connections.
4.1. Getting Started
Unpacking
Be careful when unpacking the product from its original packaging.
If using with an MDL-003, avoid applying any force to optical fiber pigtails, and do not let
any free-drop of fiber connectors occur at any time. Excessive force to fiber pigtails may
degrade device performance or damage the variable optical delay module.
Observe standard ESD precautions when unpacking the board.

Figure 5 Setup diagram
The electrical connections necessary to operate an MDL-003 or other stepper motor
using this driver board are shown in Figure 5.
1. Power supply: The board requires +12~+32VDC (1A).
2. MDL-003: The MDL-003 electrical cable plugs directly into the 10-pin connector
on the right side of the board, as shown in the figure.
3. Control circuit: The user needs to provide 3 inputs to drive the motor.
