How to use
Ensure both devices are powered off before connecting the D-Sub connectors to prevent data errors during hot plugging. Align the connector pins with the port and secure any fastening screws to maintain a stable physical connection. After connection, power on the devices and verify communication settings such as baud rate, parity, data bits and stop bits to match the connected equipment.

Avoid sharp bends and kinks; allow gentle curves with a radius at least five times the cable diameter. For permanent installations, fasten the cable with non-compressive clips and avoid excessive tensile force on the connectors.
