Introduction
The DPC50501 is a single axis programmable controller, a 5 amp bipolar microstep driver, and 
a 48VDC 65W power supply package.  It provides fl exible, independent control of bipolar step 
motors with a current range from 0.5 to 5.0 amps and microstepping resolutions of 1, 2, 5, 8, 10, 
16, 32 and 64.  The easy to use software, SMC50WIN, can be used to directly control motion and 
to program the controller.  The DPC50501 also has the ability for real time functions.  A...

Baud Selection
The baud rate is selected using 3 jumpers (JP1 - JP3).  They are selected the same way that the 
address jumpers are selected.  The table below shows how to confi gure the jumpers for a given 
baud rate.  JP3 is the LSB and JP1 is the MSB.

RS485 Protocol
The RS485 protocol is as follows, onboard receivers will remain in active mode indefi nitely.  
Transmitters must be turned off when the unit is not sending data to prevent the line from send-
ing and receiving data at the same time.  Therefore when the PC is transmitting data its driver 
will be turned on and each of the units connected will have their drivers off.  If they are requested 
to send data back to the PC, the selected unit will turn it’s driver on to...

Terminating Resistor
To eliminate noise on the transmission lines a terminating resistor may need to be used.  If needed 
the termination resistor need only be added to the last (furthest from the converter box) controller 
in the network.  A termination resistor with a value of 120 ohms is needed in certain conditions; 
when using a 4000ft. or longer cable and a baud rate of 38400 or when using a 2000ft. or longer 
cable and a baud rate of 57600.  If you need to add a terminating...

Microstep Selection (SW1 Settings)
Switches 2, 3 and 4, of the DIP switch select the number of microsteps per step.  The table below 
shows the standard resolution values along with the associated positions for the select switches.  
The standard waveforms are sinusoidal.  Switch 1 selects the auto reduce current enable or dis-
able.  With Switch 1 On, reduce current is enabled, with Switch 1 Off, reduced current is disabled.
