StarTech GC98MF DB9 to RJ45 Modular Adapter
Overview
The StarTech GC98MF is a compact modular adapter designed to bridge serial communication to Ethernet networks. It allows you to connect legacy serial devices, such as console servers or industrial equipment with DB9 ports, to modern network infrastructure using standard RJ45 cabling. This adapter is ideal for extending serial connections over longer distances or integrating older hardware into IP-based systems without requiring complex converters or new serial ports on your network devices. The GC98MF model features a male DB9 connector on one end and a female RJ45 connector on the other, facilitating a direct link between compatible serial and network interfaces.
Compatibility
This adapter is designed for broad compatibility with any serial device featuring a standard DB9 male connector and any network device or cable terminating in an RJ45 female port. It functions as a passive adapter, meaning it does not require external power or software drivers. Its utility extends to various applications, including connecting serial consoles for network equipment management, integrating serial printers into networked environments, or extending serial data acquisition systems where Ethernet infrastructure is already in place.
Installation Notes
The StarTech GC98MF requires no special installation tools or software. Simply connect the DB9 male end to the serial port of your device and the RJ45 female end to your network cable or port. The adapter's compact dimensions (3.3 in. / 8.5 cm length, 1.3 in. / 3.4 cm width, 0.6 in. / 1.6 cm height) and lightweight design (0.6 oz. / 17.5 g) make it unobtrusive in any setup. Ensure the connected serial device is configured for the appropriate baud rate and communication protocol for successful data transmission over the Ethernet link.
