Cabo null modem InLine DB9 fêmea / fêmea, moldado, vermelho, 3 m

InLine null modem cable with two 9-pin Sub D female connectors, molded for durability and intended for direct data transmission between PCs, notebooks or servers via serial COM ports. The cable is 3 m long and comes in red, suitable for connecting serial devices without using an external modem. Note: pay attention to the PIN assignment.

Advantages

The molded female/female DB9 connectors provide a robust connection and reduced strain at the cable ends. A 3 m length offers flexibility for device placement while maintaining signal integrity for short-distance serial communication. The distinct red colour makes the cable easy to identify among other leads.

Suitable for

• Direct serial communication between two PCs or notebooks
• Connecting servers or serial-enabled networking equipment
• Linking industrial devices and legacy hardware that use DB9 COM ports

How to use

Connect each DB9 female connector to the corresponding serial COM port on the two devices. Ensure the PIN assignment matches the required null modem wiring for your equipment.

Recommendations

Verify PIN assignment and wiring before use and avoid routing the cable near strong electromagnetic sources to reduce interference. For reliable operation, use for short to medium distances typical of desktop or rack-mounted equipment.
