Monoprice 25ft / 7.62m Null Modem Serial Cable | DB9 Female to DB25 Male | 100482

Yes. Since we've now confirmed it is a Null Modem cable, I would update the description. The important change is removing the references to a normal AT modem cable and explaining that the transmit/receive lines are crossed for direct serial communication.

Description

Connect compatible legacy computers and serial equipment directly with the Monoprice 25ft / 7.62m Null Modem DB9 Female to DB25 Male Molded Serial Cable.

Unlike a standard modem cable, this Null Modem cable uses crossed transmit and receive connections, allowing compatible RS-232 devices to communicate directly without requiring a modem between them.

It features a 9-pin DB9 female connector on one end and a 25-pin DB25 male connector on the other, making it suitable for compatible computers, terminals, industrial equipment, communications hardware and other legacy serial devices.

With its generous 25ft / 7.62m (762cm) length, this cable is particularly useful where serial equipment needs to be positioned some distance from the connected computer or control system.

The moulded connector construction provides a durable connection, while integrated securing hardware helps keep the cable firmly connected to compatible serial ports.
