Installation Guidelines

• Integration: This module is designed to be installed as part of a CX2040 CPU assembly. Ensure proper alignment and secure mechanical locking when mounting the module to the CPU base.
• Wiring: Use high-quality shielded twisted-pair cabling for the RS485 connection to minimize electromagnetic interference (EMI).
• Network Termination: Since the terminal termination is set to "off" by default, ensure that appropriate termination resistors are added at the physical ends of the RS485 bus to prevent signal reflections.
• Environment: Ensure the host CPU system is mounted in a clean, ventilated enclosure protected from excessive moisture, heat, and vibration, consistent with CX2040 series requirements.
