A: Shop Floor Automations ships a DB25 RS232 tester with every hardware order. We terminate our RS232 cabling with RJ-45 connectors and have different adapters to tailor to each installation. Depending on your machine you may require different pin-outs on the adapters.
To test the correct pin-out in the cabling":
Connect the cable to the PC, Hub, or switch box.
At the other end of the cabling, where the control would normally plug in, connect the tester. With out the tester plugged in the machine, you should see have "RD" lit and "TD" unlit.
Note - For most applications, the other lights do not matter.
If you plug the tester into the CNC machine control, you should then see "TD" lit.
If you have any variation of this, your machine will not communicate properly.
