Microconnect IBM029B-1,8 serial cable Black 1.8 m DB-9 DB-25

The Microconnect Serial Cable IBM029B-1,8 is a 1.8 metre cable with a DB-9 connector on one end and a DB-25 connector on the other, designed for serial data transmission between devices. Its black outer sheath and lightweight construction make it suitable for permanent installations as well as temporary connections in office, industrial and laboratory environments. The cable provides a straightforward wired link where RS-232 or similar serial signalling is required and fits equipment that accepts DB-9 and DB-25 ports.

Advantages

This serial cable offers a reversible, plug-and-play connection between DB-9 and DB-25 interfaces without the need for adapters or conversion boxes. The 1.8 m length provides flexibility for desk-to-device and rack-to-equipment wiring while avoiding excess slack. The black jacket resists common handling wear and helps keep installations visually discreet. Lightweight construction reduces strain on connector housings and simplifies routing in confined spaces.

Suitable for

• Connecting legacy serial devices (RS-232) with DB-9 and DB-25 ports
• Linking modems, printers, instrumentation, and serial terminal equipment
• Office, laboratory, and light industrial serial communications
• Temporary test setups and permanent point-to-point serial links

Key specifications

• Cable length: 1.8 m
• Connector A: 9-pin D-sub (DB-9)
• Connector B: 25-pin D-sub (DB-25)
• Color: Black
• Construction: Lightweight insulated cable with molded connector housings
• Intended signal type: Serial data (RS-232 and compatible interfaces)

How to use

Align the DB-9 and DB-25 connectors to the corresponding device ports and secure each connector using the built-in fastening screws to ensure a stable connection. Verify pinout compatibility for the specific devices you are connecting and configure serial communication parameters (baud rate, parity, data bits, stop bits) in the host and peripheral devices. Route the cable to avoid sharp bends and sources of electrical interference. If needed, power down equipment before connecting or disconnecting the cable to prevent unintended signals or damage.

Recommendations

For reliable performance, use this cable within its intended 1.8 m length and avoid exceeding recommended bend radii. Keep the cable away from high-voltage power lines and heavy machinery that generate electromagnetic interference. When connecting critical equipment, confirm signal ground continuity and test the link before final deployment.
