DDCS3.1 how to connect to Gecko drive

Dean

How do I connect DDCS3.1 controller to Gecko drives?    See attached image of Gecko with pinout.


Machine presently wired with common +5V connection to all drives on each axis.  Step and direction assume a grounding pulse.

DDCS3.1 manual state pulse and direction are "differential" +- 5V.

I decided to use two quad differential line receiver SN75173  to convert step and dir signals from DDCS3.1 unit to work with Gecko step drivers
Wish me luck...  I will report here if success.

Administrator - Please add DDCS3.1 separate forum and move this topic there to help others.

我决定使用两个四路差分线接收器SN75173来转换来自DDCS3.1单元的步进和dir信号，以与Gecko步进驱动器一起使用
祝我好运...如果成功，我将在这里报告。

管理员-请添加DDCS3.1单独的论坛，并将本主题移至其他论坛以帮助他人。

Success.  I put two SN75173 on a small perf board.   I ran each axis +-STEP +-DIR signals from DDCSV3.1 to differential inputs.
This provided a +5 to to ground output that is compliant with the Gecko drives.
This board runs on a separate 5v supply.  5v from this supply also went out to each Gecko driver board on the machine (pre-existing wiring I did not want to change). The supply shares the same ground COM- for I/O on the DDCS.   


成功。 我在一个小的穿孔板上放了两个SN75173。 我将每个轴的+ -STEP + -DIR信号从DDCSV3.1运行到差分输入。
这提供了与Gecko驱动器兼容的+5接地输出。
该开发板在单独的5v电源上运行。 来自此电源的5v电压也传到了机器上的每个Gecko驱动器板上（我不想更改的已有接线）。 电源在DDCS上共享用于I / O的相同地面COM-。

Hello Dean, I would like to know if you would like to give me ease on connecting my Gecko G251x Drivers with the DDCSV3.1.
thank you so much

I have used the line receiver SN75157P and it works fine. See drawing
