Starting up Start with power supply OFF.
NOTE: If using RS232 Converter,
disregard instructions for USB.
1. Download and install the EZCommander™ application from
www.allmotion.com/support.
2. If using USB-to-RS485 Converter, download and install appropriate USB
driver from www.allmotion.com/support.
3. Connect power supply to RS485 Converter. Ensure power is OFF.
4. Connect EZ Stepper to RS485 converter.
 If using EZ Start kit, use cable provided. If not using kit, wire mating
4-pin connectors pin-to-pin per the markings on the connector, for
example pin A to pin A. (See Wiring Note below.)
Turn power ON. Confirm that green Life LED slowly blinks. If not, look

for bad power connection.
5. Set address switch firmly to number 1 with Philips screwdriver.
6. Cycle power OFF/ON if address switch was moved in preceding step.
7. With USB cable from Converter to PC unplugged: Start the EZCommander
application (see other side of sheet for instructions if needed). Click Settings,
then Re-scan Ports. Note available ports, then click OK.
8. Connect RS485 Converter to a PC USB port with the cable supplied.
9. In EZCommander, click Settings, then Re-Scan Ports. Select the new port that
becomes available, and click OK. (For RS232 converter, the new port will be
com1.) If no new port appears, a problem with the USB driver is indicated.
Re-install the driver for your system.
10. In EZCommander, click Send String 0 to issue the command /1&. Confirm
return message showing product name and firmware version. If return message
says "No EZStepper Found", troubleshoot communications (page 2) before
connecting motor.
11. With power OFF, connect stepper motor to middle
four pins of the motor connector as shown in
diagram. (See Wiring Note below.) If using unipolar
motor, leave center taps unconnected.
CAUTION!
Always turn off power before
connecting or disconnecting motor
to avoid damaging circuit board.
12. Turn power ON.
13. In EZCommander, click string 2 to issue the command /1A1000A0R
(use /1A100000A0R for EZHR17EN or EZHR23ENHC). Confirm that the
motor goes back and forth.
You're on your way!

A quick guide to the EZStepper
This guide applies using the USB-to-RS485 Converter or RS232-to-RS485 Converter.
Your EZStepper® Controller/Driver and stepper motor.
RS485 Converter: USB-to-RS485 or RS232-to-RS485, with
cable supplied.
PC with port to match RS485 Converter being used (USB or
serial D). .
Power supply, 12 to 40V. For first-time EZStepper users
we recommend a current-limited power supply to
protect against miswiring.
Crimp tool (recommended): T-handle crimp tool, Digikey
part A9982. Otherwise, soldering equipment.
Small Philips screwdriver for operating address switch
If troubleshooting is required: ohmeter, oscilloscope

Precautions
 Observe all electrostatic discharge precautions to avoid
damaging circuit boards.
 Allow at least 0.1" air gap when bolting EZStepper to
motor, for cooling.
 Use 4-40 round standoffs to bolt EZStepper to motor,
NOT hex (Hex standoffs will touch components).
 DO NOT disconnect motor wires while power is on, to
avoid damage to circuit board.
 DO NOT place EZStepper board or RS485 Converter
on metal surface when powered (to prevent shorts).
 Avoid bundling encoder or IO wires with motor power
wires, as this may cause noise pickup from motor
wires. If bundling is necessary, put motor wires in a
separate shielded twisted-pair cable.
-For 10' or longer, shield each IO line individually.
-If using ribbon cable, add grounds between signal
wires and motor wires.

Wiring Note

Always wire to the mating connectors supplied on
circuit board. Use crimp tool if you have it, or else
solder. (DO NOT solder to circuit board; damage is
likely. Also, DO NOT press in with a screwdriver,
because this makes unreliable connections.)
