Serial Cable DeLOCK 86579 Black 2m RS-232 Sub-D9

The DELOCK 86579 is a 2-meter RS-232 Sub-D9 serial cable in black designed for reliable wired connections between devices with standard serial ports. The cable provides a straightforward solution for data transmission in environments where a stable, low-latency serial link is required. Constructed with quality connectors and a durable outer jacket, it supports routine communication tasks in both professional and home settings.

Advantages

This serial cable offers stable electrical contact through precision Sub-D9 connectors that reduce connection loss and intermittent signals. The 2 m length balances reach and signal integrity for common desktop and equipment-rack configurations. The black PVC jacket resists abrasion and general wear, while the connector housing provides strain relief to extend service life. The cable is compatible with standard RS-232 pinouts for broad interoperability with modems, industrial controllers, POS terminals and legacy computer equipment.

Suitable for

• Connecting PCs, laptops or single-board computers to serial peripherals
• Linking industrial controllers, PLCs and measurement instruments
• Data transfer between serial modems, POS systems and barcode scanners
• Maintenance, configuration and firmware updates of networked devices with RS-232 ports

Key specifications

• Cable type: RS-232 serial cable with Sub-D9 connectors
• Connector gender: male-to-female (standard Sub-D9 configuration)
• Length: 2 meters
• Color: black
• Jacket material: flexible PVC for mechanical protection
• Usage environment: indoor, industrial and office applications

How to use

Connect the male Sub-D9 plug to the serial port of the host device and attach the female Sub-D9 connector to the peripheral device. Ensure both devices are powered down when making the connection if recommended by the equipment manufacturer. After connection, power the devices and verify communication settings such as baud rate, parity, data bits and stop bits in the host and peripheral software to establish a successful RS-232 link.

Recommendations

For optimal signal integrity, avoid routing the cable parallel to high-voltage power lines or sources of electromagnetic interference. Use moderate bends and avoid tight kinks; secure the cable with cable ties or clips to prevent strain on the connectors. Store the cable in a dry environment when not in use and inspect connectors for damage before connecting to sensitive equipment.
