## Long description

This DeLOCK Serial Cable RS-232 (model 87278) is a full-handshake null modem cable with DB-9 (mini D-Sub 9) female connectors on both ends. It supports hardware flow control using RTS/CTS and DTR/DSR and allows direct connection between RS-232 devices; the RI line can optionally supply power to connected devices. The compact mini D-Sub 9 plug housing (44 x 33.3 x 15 mm) enables installation of adjacent RS-232 ports without interference.
Advantages
The cable provides full handshake support (RTS/CTS, DTR/DSR) for reliable serial communication. Its 1 m length and 5 mm diameter offer a balance of flexibility and durability. Female-to-female DB-9 connectors permit direct null modem connections between devices without additional adapters. The narrow connector housing helps when using multiple RS-232 ports close together.
Suitable for
 Connecting two RS-232 devices directly in a null modem configuration
 Serial data transfer where hardware flow control (RTS/CTS, DTR/DSR) is required
 Industrial equipment, legacy PCs, networking hardware, and serial consoles

How to use
