How to Connect

To connect the R208 according to Figure 4, begin by connecting your step motor to

the R208, for details on how to make that connection refer to Section 8 – Motor

Connections. Next, connect the DB-9 mating connector to the R208.

If using a function generator, take the positive end and connect it to Pin 9 (Step) and

connect the negative end of the generator and connect it to the negative of the +5

VDC power supply. Take the positive end of the +5 VDC power supply and connect it

to Pin 8, the Opto Supply. (Refer to Table 6 for Opto supply resistor values)

Finally, connect the external +12 to +24 VDC power supply. Connect Pin 1 (Power)

to the positive terminal of the power supply. Connect Pin 6 (Power Ground) to the

negative terminal of the power supply.

Remember that the default Current is set to 1.4 Amp. BE SURE NOT TO BURN

YOUR STEP MOTOR WITH THIS DEFAULT CURRENT SETTING. In order to

change this value, please see the section above called “Adjusting the Output

Current”.
