Grey USB to DB25 serial adapter cable with PVC jacket

Bolton Technical

Bolton Technical USB RS232 DB25 Serial Adapter Cable 16ft

SKU CH-6DJR-EWM7Z

Connects USB to RS232 DB25 for Fanuc CNC DNCLINK configuration using an FTDI FT232RNL chip over a 16ft pure copper cable

  • USB connectivity for Fanuc CNC DNCLINK configuration
  • FTDI FT232RNL chip ensures reliable serial communication
  • 26 AWG pure copper conductors for signal integrity
  • 0 mm PVC jacket protects against wear
  • 16 ft length suits workshop layouts

Industrial serial link

This Bolton Technical adapter converts a USB port to an RS-232 DB25 connection for Fanuc CNC DNCLink configuration and copy setting tasks. The 16ft cable uses an FTDI FT232RNL chip to provide reliable serial communication with industrial equipment. It targets technicians and engineers who need to interface modern computers with legacy machine-tool controllers.

Plug-and-play integration

The DB25 male connector mates directly with Fanuc CNC ports while the USB-A plug fits any standard host port, requiring no external power supply. A 26AWG pure-copper conductor and 4.0mm PVC jacket protect signal integrity across the 1.8m or 5m length options. This frees up PCIe slots and avoids the need for dedicated serial expansion cards inside the control cabinet.

Sustained data transfer

The FTDI chipset maintains stable throughput during long configuration uploads or multi-megabyte program transfers without timing errors. Shielded construction resists electromagnetic interference from nearby servo drives and spindle motors on the shop floor. The cable is not suited for applications that demand galvanic isolation or voltage levels outside standard RS-232 specifications.

Questions about this item

Will the 26AWG pure-copper conductors handle continuous data transfer without signal loss?

The cable uses 26AWG pure copper with a 4.0 mm PVC jacket, which maintains signal integrity over the full 16 ft length during sustained CNC configuration sessions.

Does the FTDI FT232RNL chip run hot or draw noticeable power during all-day CNC use?

The FTDI FT232RNL is a low-power USB-to-serial bridge that stays cool and draws minimal current even during continuous DNCLINK copy operations.

Must the Fanuc CNC already have a DB25 RS232 port for this adapter to work?

Yes — the DB25 male connector plugs directly into the Fanuc CNC's RS232 DNCLINK port, so the machine must provide that interface.
