CP-134U Series User’s Manual Connection Cables and Cable Wiring Impedance Matching and Termination Resistors When using RS-422/485 serial communications, an electrical signal that travels through two different resistance junctions in a transmission line will sometimes give rise to signal reflection due to the impedance mismatch. Signal reflection causes signal distortion, which in turn contributes to communication errors.
6 Chapter 6 Troubleshooting Common CP-134U Series problems and possible solutions are listed below. If you cannot find a solution to your problem in this chapter, contact your dealer or Moxa for help. For your convenience, a standard Problem Report Form is given at the end of this manual. General Troubleshooting 1. The MOXA PCI board cannot be detected by the MOXA driver while installing the driver. Hardware causes and solutions: a. The board is not installed in the computer. Please install it. b.
CP-134U Series User’s Manual Technical Reference Windows NT This section is specifically for troubleshooting under Windows NT. For general problems and solutions, see the previous section, “General Troubleshooting.” 1. After the system reboots, the error message “Another driver in the system, which did not report its resources, has already claimed the interrupt used by xxx.” appears in the Event Log. This indicates the MOXA board was found, but the IRQ is conflicting with another adapter.

CP-134U Series User’s Manual Technical Reference PCI The 32-bit CP-134U Series board complies with PCI Specifications 2.1. The IRQ and I/O address hardware configuration is automatically assigned by the PCI BIOS. This means that you must first plug in the board before installing the driver software. As opposed to ISA slots, different PCI slots in the same PC may have different bus numbers and device numbers with respect to the PCI specifications.
