Unfortunately, there is no information about how to attach a load cell cable to this device. From what it seems, the product comes with one control cable - CR-6460 and 8 sensor input conversion cables - CR-6186. Also, it can be connected to a PC using a USB cable. If you need to plug in another cable, you will need to consult a specialist. I suggest you contact Tokyo Sokki Kenkyujo for further information.
