I’m Getting Communication Time Out Errors And I Can’t Get The Dev

1.	I’m Getting Communication Time Out Errors And I Can’t Get The Device To Communicate With My Software? What Could Be Wrong?
Answer» Transmit and receive signals can OFTEN be verified by watching the transmit and receive lights on the MODBUS components. The communication parameters are not SET up correctly on the device. Check the settings match for slave address, baud rate, STOP bit and parity. MAKE sure the host software has the same configuration The transmit and receive wires are crossed. Try switching the wires as it will not cause any damage. Check the conductivity on each wire for loose connections or broken wires. High power lines or improper grounding is causing noise in the system. Are the communication cables shielded and is the shield grounded on one end.
