## Long description

Null modem cable PREMIUMCORD R99Cross with 9-pin D-sub (DB9) male-to-female connectors and crossed wiring. The adapter changes connector wiring to swap transmit and receive lines, enabling direct serial communication between two devices without a modem. Compatible with RS-232 ports and two-row DB9 connectors.
Advantages
The PREMIUMCORD R99Cross offers a ready-made crossed (null modem) connection in a compact adapter format, simplifying setup when connecting two serial devices. Using standard 9-pin D-sub connectors ensures broad compatibility with legacy serial equipment and industrial devices. The male-to-female configuration allows easy insertion between existing cables or devices.

How to use
Plug the DB9 male end into the female serial port of one device and connect the DB9 female end to the male serial plug of the other device or cable. The adapter swaps the transmit and receive signals so the two devices can exchange data directly. No additional configuration is required on the adapter itself; serial port settings (baud rate, parity, stop bits) should be set on the devices as needed.
Usage recommendations
Use this null modem adapter for short-distance serial connections and configuration tasks. Verify RS-232 voltage levels and pinouts of connected equipment before use. For long runs or where signal integrity is critical, consider using shielded cables or line drivers designed for extended distances.
