Yamaha KAX-M657E-010 RS-232C Data Cable Adapter

Yamaha · Robot Programming · Serial Communication · In stock

The Yamaha KAX-M657E-010 is a dedicated RS-232C serial data cable adapter used to program, commission, and troubleshoot Yamaha industrial robots and pick-and-place equipment. It bridges a PC serial port (DB9) to the dedicated programming port on a Yamaha RCX-series controller, allowing engineers to upload and download motion programs, I/O tables, point data, and servo parameters through the official RCX Studio / VIP+ toolchain.

For B2B industrial automation integrators, system builders, and field service engineers, the KAX-M657E-010 is the standard service cable referenced in Yamaha SCARA robot documentation. It is the same harness shipped with new YK / YAS / YSM series robots as the factory programming lead, and is also the most widely used replacement cable when the original is lost or damaged on a working cell.

KOEED stocks the KAX-M657E-010 alongside the broader nine-brand industrial automation portfolio (Allen-Bradley, Siemens, Mitsubishi, Omron, Fanuc, Schneider, Yaskawa, Panasonic, KEYENCE), so a single BOM can cover both the Yamaha robot cell and the surrounding PLC, HMI, and vision-system serial interfaces that share the same RS-232C / RS-422 / RS-485 landscape.

Key Specifications

Datasheet Highlights

• Null-modem wiring profile. The KAX-M657E-010 is wired as a cross-over (null-modem) harness so the PC's DTE signals line up with the controller's DCE programming port without an external converter. RD ↔ TD, RTS ↔ CTS, DTR ↔ DSR are crossed per the Yamaha RCX-series service manual.
• Shielded twisted-pair construction. Each signal pair is twisted and overall foil-shielded to reject the common-mode noise found around servo drives, VFDs, and welding lines — the same noise budget that any RS-232C link in a factory automation cell has to survive.
• Plug-and-play with RCX Studio. No driver or option-board configuration is required on the host PC. Once the cable is connected and the controller is in TEACH or AUTO (REMOTE) mode, RCX Studio detects the controller and exposes upload / download / monitor functions out of the box.
• Cross-platform Windows host support. Verified against Windows XP / 7 / 10 / 11 hosts using the official Yamaha USB-to-serial bridge or native DB9 COM port. Default communication parameters are 9600 bps, 8 data bits, no parity, 1 stop bit — matching the RCX-series default.
• Direct replacement for the original service lead. Pin-for-pin compatible with the cable Yamaha ships in the YK / YAS robot accessory box, so it is a drop-in spare for cells where the original cable has been lost, damaged, or routed through a cable carrier beyond its flex rating.

Typical Applications

• Initial commissioning of Yamaha SCARA cells. Used by system integrators during factory acceptance testing (FAT) to load point tables, I/O maps, and motion programs into a fresh YK-X / YK-TW robot before the line is handed over to production.
• Field service & troubleshooting. Field engineers keep a KAX-M657E-010 in their service kit to read fault histories, dump servo parameters, and recover programs from controllers that have lost their backup battery.
• Pick-and-place programming in SMT lines. The cable is the standard service lead for the YAS series pick-and-place heads used in surface-mount assembly, where recipe upload / download and feeder calibration are routine maintenance tasks.
• Robot-to-PLC data handshake validation. When integrating a Yamaha cell with a ControlLogix or SIMATIC S7 PLC, the same RS-232C channel is often used for diagnostic handshakes before Ethernet/IP or PROFINET is brought up. The KAX-M657E-010 is the local engineering access path during that bring-up window.
• Robotics training & education cells. Technical schools and OEM training rooms use the cable to teach RCX programming on YK-series didactic cells, since the same lead works on every RCX40 / RCX240 controller in the lab.
• Refurbished-equipment recommissioning. Third-party refurbishers and used-equipment exporters re-flash and re-teach incoming Yamaha robots before resale; the KAX-M657E-010 is the cable referenced in their standard work-instruction set.

Related Modules & Cross-Reference

The KAX-M657E-010 lives in the same RS-232C / RS-422 / RS-485 world as the serial communication modules and vision-system serial ports across the KOEED nine-brand matrix. The table below maps typical cross-brand replacements and companion parts engineers look at when building a Yamaha cell into a larger line.

Warranty & Authenticity

• Pre-shipment continuity test. Every KAX-M657E-010 is continuity-checked end-to-end (pin ↔ pin) before packaging, so a known-good cable is what reaches the integrator's bench.
• Genuine Yamaha service-cable spec. Sourced through KOEED's China Sourcing Company supply chain against the original Yamaha wiring diagram, not a third-party clone with a substituted pinout.
• Worldwide shipping. DHL / FedEx / UPS dispatched from Shenzhen and Hong Kong with full export documentation, typically 3–5 business days to most major automation markets.
• 24-hour quote turnaround. Send a single-line RFQ or a full BOM to Moritta@KOEED.COM and KOEED replies with availability and a quote within one business day.
• B2B-only quotation model. Pricing is held on the quote, not on the page — this keeps the cable in line with KOEED's standard industrial-automation sourcing workflow and supports the larger BOM each robot cell usually sits inside.
