DeLOCK 87786 Serial Cable Black 1 m DB-9

The DeLOCK 87786 is a 1 m serial cable with mini D-Sub 9 (DB-9) connectors designed for connecting two RS-232 devices for data exchange. The cable is black, has a 5 mm diameter and supports CTS/RTS auto control, making it suitable for printers, measuring instruments, converters, RS-232 hubs and patch panels.

Advantages

The fully wired null modem wiring enables direct device-to-device communication without additional adapters. Compact mini D-Sub 9 connectors allow installation in tight spaces and adjacent RS-232 ports. CTS/RTS auto control provides hardware flow control automatically, and the 1 m length balances reach and signal integrity for common setups.

Suitable for

• Connecting serial printers
• Linking measurement instruments and data loggers
• Connecting RS-232 converters and hubs
• Patching devices on patch panels with DB-9 ports

Key specifications

How to use

Connect each DB-9 connector to the RS-232 port of the two devices to be linked. Ensure the connectors are fully seated and fasten any thumbscrews if present. The null modem wiring handles transmit/receive crossover internally and CTS/RTS auto control negotiates hardware flow control automatically; no additional configuration is usually required on devices that support hardware flow control.

Recommendations

Use the cable within its 1 m length to maintain reliable RS-232 signal levels. Avoid sharp bends and prolonged exposure to heat or moisture. For devices that do not support hardware flow control, verify device settings and, if necessary, use software flow control.
