VGA Cable DeLOCK 86886 0.5m D-Sub Black

This Delock serial cable is a full handshaking null modem cable that enables direct data exchange between two RS-232 devices such as printers, measuring instruments, converters, RS-232 hubs and patch panels. The cable has compact mini D-Sub 9 connectors that fit standard RS-232 ports and allow adjacent connections.

Advantages

The cable provides full hardware handshaking for reliable serial communication and uses shielded wiring to reduce interference. Its compact D-Sub 9 connector dimensions (approx. 44 x 33.3 x 15 mm) allow tight placement of connectors, and the 28 AWG conductors with PVC insulation ensure basic flexibility and durability for short serial links.

Suitable for

• Connecting two RS-232 devices directly (null modem)
• Printers and measuring instruments with DB9 ports
• Converters, RS-232 hubs and patch panels requiring full handshaking

Key specifications

• Connector 1: 1 x D-Sub 9 male with screws
• Connector 2: 1 x D-Sub 9 female with nuts
• Cable gauge: 28 AWG
• Pin assignment: 1+6 → 4, 2 → 3, 3 → 2, 4 → 1+6, 5 → 5, 7 → 8, 8 → 7; shielded
• Colour: black
• Insulator: PVC
• Screw type: #4-40 UNC
• Cable diameter: approx. 5 mm
• Cable length including connectors: approx. 0.5 m

How to use

Connect the male D-Sub 9 connector to the RS-232 port of one device and the female D-Sub 9 connector to the other device, then fasten the screws and nuts to secure the connection. The null modem pinout and full handshaking lines are already wired, so no additional wiring or configuration is required on typical RS-232 equipment. Use the cable for short-distance serial communication where a direct device-to-device link is needed.

Recommendations

For reliable performance keep the cable length short and avoid routing it alongside high-power cables. Ensure both devices use standard RS-232 voltage levels and that serial port settings (baud rate, parity, stop bits) match on both devices before starting communication.
