About this task

Note: The NAE85 model does not support diagnostic mode at the serial port. Use the USB drive capture method instead.
Note: The SNE and SNC do not have a built in RS-232 interface. To enable RS-232 communication, use a ACC-USBRS232-0 or ACC-USBRS485-0. Refer to SNE/SNC Product Bulletin (LIT-12013296) for ordering information.

Procedure

  1. To activate diagnostic mode, connect a null modem cable between the computer's serial port and the NxE port (RS232C A or RS232C B), or connect the certified ACC-USBRS232-0 USB-to-RS-232 adapter to the SNE or SNC and then connect a null modem cable between the computer's serial port and the adapter.
  2. Start a compatible serial communication program on the computer, for example, HyperTerminal or PuTTY. Configure the communication settings for the diagnostic messages according to the values in Table 1.
