Serial Extension via Network Cable
The SMUGDESK DB9 RS232 Female to RJ45 Female Adapter converts a standard DB9 serial COM port to an RJ45 interface. It lets you transmit RS232 signals over ordinary CAT5, CAT5e or CAT6 cable for long-distance runs. No external power supply or driver is needed, making it a simple plug-and-play solution for industrial equipment.
Passive Wiring Distance Limits
Because the adapter uses a passive wiring design, the practical extension distance depends on cable quality and the serial device itself. The supplier notes reach of up to dozens of metres, but signal integrity will vary with baud rate and electromagnetic interference. Plan for shorter runs at higher speeds or in electrically noisy environments.
Check Your Port Gender and Pinout
Before ordering, confirm that your equipment presents a DB9 male connector and an RJ45 female jack for the network cable. Verify the RS232 pin assignment matches the adapter’s straight-through wiring, as some industrial gear uses non-standard pinouts. This unit is not suited for setups requiring active signal conversion or protocol translation.
