Use of USB OTG
The drive performs USB host function to search for firmware files in the USB memory and download
them to flash memory inside the drive. You can easily update the firmware using the USB memory and
OTG cable without a PC. The update procedure is as follows:
(1) Prepare a download cable (USB OTG cable) and a USB memory.
Use a USB OTG cable, consisting of USB Female Plug Type A and USB Mini B 5 pins, as the
download cable.
+
(2) Copy the firmware file (L7NH_FW.bin) to update to the USB memory.
*Caution
1. The L7NH_FW.bin file should be placed in the root directory of the USB memory, and the full
file name including the extension should match.
2. The formatting type of the USB memory has to be set to FAT32 (default).
(3) After connecting the USB memory to the USB OTG cable, connect it to the USB terminal and
power on the drive.
(4) When 7-Segment for servo status display shows ‘boot’ and then ‘otg’, it indicates that update is in
progress. Three horizontal bars of FND Digit5 are sequentially turned on from bottom to top, it
indicates that download is complete. At the time, remove the USB OTG cable and USB memory.
(7-segments display a message when downloading the firmware using the OTG)
