66 480 Legend Series
Example:
If the standby parameter set to 1 second, the weight threshold to 100, and the display division threshold is set to
10d, once in sleep mode, the indicator will wake up every second for about half a second to check to see if a key is
being pressed, the weight threshold is over 100 (WGTHRH), or the weight has change more than 10d (DDTHRH)
since the last time it checked.
Setting the standby parameter to a higher value reduces the amount of time the indicator is awake, this will increase
battery life.
An
OFF
setting stops the indicator from waking up. The only way to wake up the indicator is to press the
Power
key.
The Power key is the only key that will wake the indicator, unless the Standby parameter is set to any setting
other than NONE. Then any key press will work to wake the indicator from standby.
9.7 Internal Battery Option
In Firmware version 1.03 and later, an optional internal rechargeable Li-ion battery is available. The battery can
replace the AC power when needed. Typical run time is 12 hours (single load cell, no options, with LED display).
The amount of time the indicator will operate on the battery depends on:
• Type of display (LED)
• If sleep mode is used or not
• How may load cells are attached
• What options are installed
The battery is automatically charged when the indicator is connected to AC power. It automatically switches to
battery power if the AC power is removed. The battery is designed to only be charged by connecting to AC power.
When operating on battery power, the indicator features a sleep mode that allows the indicator to go into a low
power mode. Using the sleep mode helps improve battery life. See Section 9.6 for more information about the sleep
mode.
When the battery life reaches 5-10 percent of capacity, the
Lo Bat
flashes on the display. When the battery life is
less than 5 percent, it will flash faster, at 0 percent, the indicator will turn off. Battery charge time is approximately
16 hours to 100 percent.
9.8 USB Option
In firmware version 1.03 and later, an optional Ethernet/USB board is supported.
The USB connection is capable of being either of the following:
• USB device (connected to a PC and appearing as an available communication port)
• USB host interface to a flash drive
• USB interface to printer
The mode of the USB option is selected in the User Menu.
9.8.1 HOST
When set to HOST mode, the USB port can be connected to a USB connection on a PC. An HCC Driver is required
on the PC.
The HCC driver is available on a CD (PN 171153) that is included with the USB/Ethernet Option. Use the
documentation (PN 171152) for the option to install the driver on the PC.
When connected to a PC, the connection will appear to applications as another serial communications port. Using
the USB trigger parameter in the
482 user menu, it is possible to set the port to act as both a serial command port
and demand print port (
DEMAND
), or as a serial command port only (
COMAND
). All EDP serial commands can be
used through the USB HOSTPC port.The USB port cannot be used to stream data.
9.8.2 Flash Drive
When set to Drive mode, the USB port can be connected to a flash drive to allow the upload and download of the
indicator configuration parameters. The data is written to the drive in a FAT32 system format; no special drivers are
required.
To use with a flash drive, first configure the
USB
parameter in the user menu to
DRIVE
. Saving the configuration to
the drive, or loading it from the drive, can only be done in the configuration menu.
