Null Modem Configuration: Internal crossover wiring eliminates the need for an intermediate modem or adapter.
Robust Shielding: Built with high-quality foil shielding to prevent EMI (Electromagnetic Interference) and ensure data integrity over the 1.8m length.
Durable Connectors: Features molded connectors with integrated strain relief and thumbscrews for a secure, wiggle-free connection.
Compatibility: Designed for legacy hardware, CNC machinery, older PLC systems, and specialized laboratory equipment utilizing the 25-pin RS232 standard.
The Roline RS232 25-pin Null Modem Cable (11.01.3918) is a specialized data transfer solution designed for direct communication between two DTE (Data Terminal Equipment) devices, such as two computers or specific industrial controllers, without the need for a modem.
Product Overview
This 1.8-meter cable features a DB25 Male to DB25 Female configuration. Unlike a standard "straight-through" serial cable, this is a null modem cable. This means the internal wiring crosses the transmit (TX) and receive (RX) lines, allowing the two devices to talk to each other directly.
