Installation Notes

• Power down or safely isolate the serial port's communication interface before attaching the cable to prevent transient voltage spikes from damaging sensitive transceiver chips.
• Align the keyed connector interfaces exactly with the host controller or modem port before fully seating the plug.
• Secure the integrated thumb screws snugly onto the mating chassis threads to ensure a vibration-proof physical and grounding bond.
• Avoid routing the communication cable parallel to high-voltage AC power lines or heavy motor leads to maintain optimal data packet throughput without CRC errors.
