## Long description

InLine B-12233 is a 3 m serial extension cable with a 9-pin (DB9) male-to-female connector designed to extend RS-232 serial connections. The cable allows direct wired extension of serial links between devices such as modems, printers, industrial controllers and POS terminals without any signal conversion. The straightforward plug-and-play design maintains the original serial pinout and provides a stable physical connection for data transfer over short distances.
Advantages
The extension cable preserves the RS-232 signal integrity by maintaining standard DB9 pin assignments and using shielded conductors to reduce interference. Its fixed 3 m length offers predictable reach for desk-to-equipment layouts and simple installation without the need for configuration or drivers. The male-to-female connectors are molded for secure mating and reliable contact during frequent insertions and removals.
Suitable for
Extending an existing RS-232 connection between a computer and a modem or serial printer
Linking industrial controllers, sensors or PLCs to serial monitoring equipment
Connecting point-of-sale (POS) terminals or barcode scanners to host devices
Temporary or semi-permanent cabling where a short, reliable serial link is required
Key specifications
Connector type: 9-pin D-sub (DB9) male to DB9 female
Cable length: 3 meters
Signal standard: RS-232 serial (no protocol conversion)
Conductor and shielding: multi-conductor cable with shielding to reduce electromagnetic interference
Connector housing: molded strain-relief for durable connection
How to use
Connect the male DB9 connector to the female serial port of the source device and plug the female DB9 connector into the target device's male serial port, ensuring that the connectors are fully seated and any retaining screws are tightened to secure the connection. Verify that both devices use compatible RS-232 signal levels and matching communication settings (baud rate, parity, data bits, stop bits) before starting data transfer. No driver installation is required for the cable itself; configuration is handled by the connected devices.
Usage recommendations
For best performance, route the cable away from strong sources of electrical noise (large motors, unshielded power cables or radio transmitters). Avoid sharp bends and repeated tensile stress near the connector ends. For longer distances or environments with high interference, consider using differential serial interfaces or a certified serial repeater.
