 motorDSM contains an example IOC that is built if ``configure/CONFIG_SITE.local`` sets ``BUILD_IOCS = YES``.  The example IOC can be built outside of the driver module.  Copy ``iocs/dsmIOC/configure/EXAMPLE_RELEASE.local`` to ``RELEASE.local`` and uncomment and set the paths for the appropriate lines depending on whether motorDSM was built inside the motor module or independently.

+You will need to set the path(s) for the serial port(s) in ``st.cmd.md90`` (for a single unit) or ``st.cmd.md90.multi`` (for multiple units).
+You will also need to ensure they match the names used in ``motor.substitutions.md90`` (or ``motor.substitutions.md90.multi``).
+By default, ports are assumed to be at ``/dev/ttyUSB0``, ``/dev/ttyUSB1``, etc.
+You will also need to comment or uncomment lines depending on the number of drivers you have connected. For each driver, make sure you uncomment/call the following functions:
+
+**1. Define a new serial port named "serial0"**
+`drvAsynSerialPortConfigure([serial name], [device location], 0, 0, 0)`  
+*e.g., `drvAsynSerialPortConfigure("serial0", "/dev/ttyUSB0", 0, 0, 0)`*

+
+**4. Create MD90 Controller object**
+`MD90CreateController([controller name], [serial name], 1, 100, 5000)`  
+where `[controller name]` is the name of the motor to assign. Convention is to use "MD90n", starting with n=0.
+
+**5. Intialize the IOC**  
+After calling `iocInit`, run the following lines for each motor. The example below uses `DSM:m0` but it should be run for each line described in motor.substitutions.md90 (or motor.substitutions.md90.multiple).
+````

+# Example usage
+
+After building, run the example IOC described at the top of this section in one terminal window.
+Open another terminal window and navigate to [EPICS install directory]/epics-base/bin/linux-x86_64/ (or wherever you built EPICS base.  
+Use the commands `caput` and `caget` to set and read process variables.  
+
+For example, to get the current position, use `./caget DSM:m0.REP`. This reads the REP variable, which is the "Raw Encoder Position". Set m0 to m1, m2, etc. for multiple motors.
+
+Other examples
+-------------------------
+
+Homing the motor (must be done before you can issue position commands):
+`./caput DSM:m0.HOMF 1			#Begins homing sequence in the forward direction`  
+`./caput DSM:m0.HOMR 1			#Begins homing sequence in the reverse direction`  
+
+Moving to a position target:
+`./caput DSM:m0.VAL 2.345		#Moves to 2.345 mm
+
+Setting a velocity target:
+`./caput DSM:m0.VELO 0.5		#Sets velocity target to 0.5 mm/s`  
+Note that velocity targets are appropriate only. They adjust the step rate of the motor, and are not guaranteed to be exact.
