Troubleshoot intermittent connectivity loss on a TD Terminal. Focus on Ethernet cable integrity, ESD, and safe handling procedures for retail environments.
Record the cable category (e.g., CAT5e, CAT6) and length.
Identify if the issue is isolated to the terminal or a broader network problem.
Determine if a recent change may have caused the connectivity loss.
Ethernet connectivity relies on stable voltage and signal integrity. Baud rate fluctuations and signal attenuation due to cable damage or electromagnetic interference (EMI) can cause intermittent disconnections. Electrostatic discharge (ESD), particularly in dry environments, can temporarily disrupt the network interface controller (NIC) operation. The TD Terminal network interface is typically auto-negotiating, so connection speed mismatches can also contribute.
Intermittent loss of network connectivity on the TD Terminal. Device may temporarily disconnect from the network, resulting in transaction errors or processing delays.
Regularly inspect Ethernet cables for damage. Use cable ties or management systems to prevent cable strain. Clean the touchscreen and surrounding areas with an approved cleaning solution designed for electronic devices to minimize ESD. Ensure the terminal is placed away from sources of strong EMI (e.g., microwave ovens, power transformers).
Try using a short, high-quality shielded Ethernet cable (CAT6 or better) to minimize EMI and signal attenuation. Also, check the link lights on both the terminal and the network switch/router to verify a stable connection is established.
