ACT D-Sub-nollamodeemiadapteri 25-pin pistoke 25-pin liittimeen

ACT AB9843 is a D-sub null modem adapter with a 25‑pole male to 25‑pole female connection designed for serial communication. Constructed from stainless steel with an orange finish, the adapter provides a compact hardware solution for creating a null modem link between two D-sub 25 devices without additional software configuration.

Advantages

The adapter converts a standard 25‑pin D‑sub connection to a null modem wiring arrangement, enabling direct device-to-device serial communication. Its stainless steel construction and colored finish improve durability and make the adapter easy to identify in installations. The plug-and-play design requires no software setup.

Suitable for

• Connecting two RS‑232 devices that require a null modem configuration
• Legacy equipment with 25‑pin D‑sub ports
• Industrial control systems and serial consoles
• Field testing and temporary cable reconfiguration

How to use

Align the 25‑pin male connector with the corresponding female port on the target device and secure the connector screws. Plug the female end into the 25‑pin male port of the other device. Verify the physical connection and power the devices as required; no software configuration is needed to establish the null modem link.

Recommendations

Use the adapter in dry, clean environments and avoid excessive mechanical strain on the connector and cable. Confirm that both devices use compatible signal levels (typically RS‑232) and that a null modem wiring scheme is appropriate for the intended communication before use.
