Usb Firmware Update - microHAM ARCO Manual

MOTOR: During rotation shows calculated current [A] taken by the rotator's motor.
TEMPTERATURE: Shows motor driver heatsink temperature [ºC]. Internal fan automatically
starts cooling if temperature exceeds 57 ºC until drops down below 47 ºC.
If ARCO firmware cannot be updated over the internet under SYSTEM menu, alternative
method is to use USB FLASH ("thumb") drive:
1. Copy the update file arco.upd available at our webpage Downloads section to the root
directory of a USB FLASH drive. Don't place the update file to any subdirectory. Don't
rename the file.
2. Turn off main power switch, push and hold the LEFT ← button, then turn main power
switch on. The red FAULT led starts to flash. The display will remain blank.
3. Insert the USB FLASH drive to the FW connector on the rear panel. POWER and
MOTOR leds will briefly flash and the MOTOR led than blink while the update file is
getting recognized and loaded into ARCO. This process should not take more than a
minute. The new firmware will be started automatically.
4. Remove the USB FLASH drive from ARCO and continue operating.
If the update process fails the POWER, FAULT and MOTOR leds will indicate the possible
cause of failure:
MOTOR and POWER leds flash – arco.upd file not found in the root directory of USB
•
FLASH drive.
POWER led lit, FAULT led flashes – connected device is not recognized as standard
•
Mass Storage Class USB FLASH drive. This might be a nonstandard device, a complex
device, e.g. embedding an USB HUB (such as the older U3 "smart drives", or the
FLASH/fingerprint combinations, etc.), or simply a different device such as a keyboard,
connected by mistake.
MOTOR led lit, POWER led flashes – USB FLASH disk's format is unknown. This may
•
happen, when the FLASH disk is partitioned or formatted in an unusual way. Use simple
and low capacity USB FLASH disks, which usually come with traditional simple partition
table and FAT file system.
Please note, that current supplied through the USB-A connector is limited to approximately
100mA, and does not allow using traditional rotary USB disks.
