Direct serial connection between 9-pin and 25-pin
Data exchange via COM ports:Null modem connection between two systems without additional hardware.
Link 9-pin to 25-pin:Connect different D-sub connectors directly.
Clearly defined pinout:Transparently documented null modem configuration simplifies installation.
Removable connectors:Simplify mounting and handling.
Practical cable length:2 m for short-distance point-to-point connections.
This null modem cable connects two serial devices such as PC, notebook, or server directly via the respective COM ports. The female-to-female design with D-sub 9-pin to D-sub 25-pin enables direct data exchange without a modem or network, for example for testing, configuring, or transferring smaller amounts of data. The clearly defined pinout supports stable communication, while removable connectors simplify handling.
It proves itself in professional IT environments, in on-site deployments and service work, and in existing infrastructures of companies and public institutions, for example when connecting serial peripherals, console ports, or retrofitting older systems.
