| Pin Function | Details |
| PUL+(+5V) | Pulse signal: In single pulse pulse/direction) mode, this input represents pulse signal, effective for each rising or falling edge (set by inside jumpers in JP1); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,effective for high level or low level (set by inside jumpers in JP1). For reliable response, pulse width should be longer than 1.5μs. Series connect resistors for current-limiting when +12V or +24V used. |
| PUL-(PUL) | |
| DIR+(+5V) | DIR signal: In single-pulse mode, this signal has low/high voltage levels,representing two directions of motor rotation; in double-pulse mode (set by inside jumper J3), this signal is counter-clock (CCW) pulse,effective for high level or low level (set by inside jumper J1). For reliable motion response, DIR signal should be ahead of PUL signal by 5μs at least. 4-5V when DIR-HIGH,0-0.5V when DIR-LOW. |
| DIR-(DIR) | |
| ENA+(+5V) | Enable signal: This signal is used for enabling/disabling the driver. High level (NPN control signal, PNP and Differential control signals are on the contrary,namely Low level for enabling.) for enabling the driver and low level for disabling the driver. Usually left UNCONNECTED (ENABLED). |

Microstep and Current
The drives uses an 8 bits DIP switch to set stepper motor resolution and motor operating current, as shown below:
Dynamic Current(1/2/3) Microstep Resolution(6/7/8)
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
Standstill Current(4,Half/Full)
Microstep Resolution Selection
Microstep resolution is set by SW5, SW6, SW7, SW8 of the DIP switch as show in following:
| Step Angle | Pulse/Rev | SW5 | SW6 | SW7 | SW8 |
| 0.9 | 400 | ON | ON | ON | ON |
| 0.45 | 800 | ON | OFF | ON | ON |
| 0.225 | 1600 | ON | ON | OFF | ON |
| 0.1125 | 3200 | ON | OFF | OFF | ON |
| 0.05625 | 6400 | ON | ON | ON | OFF |
| 0.028125 | 12800 | ON | OFF | ON | OFF |

| 0.0144 | 25000 | OFF | ON | ON | OFF |
| 0.0072 | 50000 | OFF | OFF | ON | OFF |
Current Settings
The first three bits (SW1, SW2, SW3) of the DIP switch are used to set the dynamic current. Select a setting that closest to your motor"s required current.
| Peak current (A) | RMS(A) | SW1 | SW2 | SW3 |
| 1.50 | 0.71 | on | on | on |
| 2.00 | 1.00 | off | on | on |
| 2.40 | 1.18 | on | off | on |
| 2.80 | 1.35 | off | off | on |
| 3.20 | 1.60 | on | on | off |
| 3.70 | 1.82 | off | on | off |
| 4.20 | 2.10 | on | off | off |
| 4.50 | 2.22 | off | off | off |
Note:Due to motor inductance, the actual current in the coil may be smaller than the dynamic current setting, particularly in high speed condition.
