DeLOCK 87525 RS-232 Serial Cable 10m Socket to Socket

This full-handshake null modem serial cable by DELOCK allows direct RS-232 device-to-device connection. It supports RTS/CTS and DTR/DSR hardware flow control and optionally can supply power to a connected device via the RI line. The compact Mini D-Sub 9 (female-to-female) connector housing is narrow to enable side-by-side connection of RS-232 ports.

Advantages

The cable provides full handshaking (RTS/CTS and DTR/DSR) for reliable serial communication and prevents data loss during transfers. At 10 m length and 5 mm cable diameter it combines reach with a slim profile, while the narrow Mini D-Sub 9 housing ensures compatibility with crowded connector panels. Female-to-female wiring enables null modem operation without additional adapters.

Suitable for

• Connecting two RS-232 devices directly (null modem)
• Industrial serial communication and control systems
• Data transfer between serial terminals, PLCs and measurement equipment
• Environments where compact connector spacing is required

How to use

Connect each Mini D-Sub 9 female connector to the corresponding RS-232 male port on the devices to be linked. Verify that the devices are configured for null modem communication and that hardware flow control (RTS/CTS, DTR/DSR) is enabled if required. If power via the RI line is needed, confirm device compatibility and voltage requirements before enabling or relying on this feature.

Recommendations

Use the cable in environments within normal temperature and humidity ranges for electronic equipment, avoid sharp bends or excessive tensile stress along the 10 m length, and check connector seating to ensure reliable RS-232 communication. Do not assume the RI line supplies power unless the connected devices explicitly support power-on-RI according to their specifications.
