Kramer Electronics C-D9F/OPEN RS-232 Control Cable, DB9 Female to Open End, 3 m, Black 95-0210010

In a broadcast control room, a technician needs to connect a Kramer switcher to a custom-built tally light system. The switcher has a standard DB9 serial port, but the tally system requires bare wire terminations. This Kramer C-D9F/OPEN cable solves the problem: one end is a molded DB9 female connector that plugs directly into the switcher, and the other end is left open with individual conductors, ready to be soldered, crimped, or screwed into the custom interface. The 3-meter length provides enough reach to route the cable neatly through the rack, and the black PVC jacket blends with existing cabling.

Key specifications

• Connector 1: DB9 female (D-sub 9-pin)
• Connector 2: Open end (unterminated, user-definable pinout)
• Cable length: 3 m (9.8 ft)
• Cable type: RS-232 serial control cable
• Colour: Black
• Shielding: Yes
• Conductor material: Copper
• Jacket material: PVC
• Max data rate: Up to 115.2 kbps (RS-232 standard)
• RoHS compliant: Yes

Why choose it

This cable is ideal for integrators and technicians who need to interface standard serial devices with custom or legacy equipment. The open end gives complete flexibility in wiring, allowing you to match any pinout or termination style. The molded DB9 connector ensures a secure and durable connection, while the shielded construction minimizes interference for reliable data transmission. The 3-meter length is practical for rack installations and equipment closets, and the black PVC jacket is both flexible and hard-wearing.

Ideal use cases

• Connecting Kramer control processors to third-party controllers with screw terminals
• Custom RS-232 wiring for AV installations, digital signage, and conference systems
• Creating adapter cables for legacy serial devices
• Field service and prototyping where a standard terminated cable is not available

Good to know

The open end consists of individual color-coded conductors, typically following a standard color scheme for easy identification. Before connecting, verify the required pinout for your specific application. This cable is part of Kramer's C-D9F/OPEN series, known for reliable performance in professional AV environments. It is RoHS compliant, meeting environmental standards. For installations requiring a longer reach, consider using a null modem adapter or an RS-232 extender.
