## Summary description

Female-to-female DB9 cable CABLE-123 provides a 1:1 pin mapping for connecting serial RS-232 devices with DB9 ports. Designed for straightforward point-to-point connections between computers, modems, industrial equipment and other RS-232 peripherals. Use where a straight-through DB9 female connector pair is required to extend or join serial cables and maintain signal integrity.

## Long description

Female-to-female DB9 cable CABLE-123 provides a 1:1 pin mapping for connecting RS-232 serial devices that use DB9 ports. The cable is intended for straightforward point-to-point connections between DTE (Data Terminal Equipment) devices, such as two computers, modems, or other serial peripherals, where a straight-through female–female DB9 connection is required to extend or join serial links while preserving signal integrity.
Advantages
The cable offers a 1:1 wiring scheme that preserves standard RS-232 signal assignments and eliminates the need for pin reconfiguration. Female-to-female DB9 connectors allow direct connection between devices or between two male-terminated cables, simplifying installation. Its simple, standardized design supports reliable serial communication without protocol conversion.
Suitable for
 Point-to-point serial connections between two computers (DTE to DTE)
 Connecting modems, serial printers, or industrial controllers with DB9 ports
 Extending or joining existing DB9 serial cables that use male connectors
Key specifications
 Connector type: DB9 female to DB9 female
 Pin mapping: 1:1 straight-through (no crossover)
 Standard: RS-232 compatible
 Manufacturer part number (MPN): CABLE-123
How to use
Connect each DB9 female end to a DB9 male connector on the devices or to male-terminated serial cables. Ensure secure mating of the connectors by tightening the thumbscrews or screws if present. Verify device serial port settings (baud rate, parity, stop bits) and signal ground reference before initiating communication. Use the cable only with RS-232-compatible ports.
Usage recommendations
The cable is intended for low-speed RS-232 serial communication; avoid using it for networks or high-frequency signals beyond RS-232 specifications. Keep cable runs as short as practical and route away from high-voltage or noisy power lines to reduce interference.
