7.2 Memory card
The gripper control unit has a slot to insert a MicroSD memory
card. Although all common variants are supported (SD and SDHC),
we recommend the use of the following memory cards:
MicroSD card:
Made by: SANDISK, type: SDSDQM-002G-B35, capacity: 2 GB
The memory cards hold the following data:
• Software needed to operate the product
• Configuration data
• Documentation and software tools (can be called up via the
web interface)
• Scripts and other user.specific data in the /user directory
The card installed by the manufacturer has a capacity of 2 GB. The
required operating software is already installed on the card. User-
specific data and scripts can be saved in the "user" subdirectory.
Please do not change or delete any files outside of this directory
as, otherwise, fault-free operation of the product can no longer be
guaranteed.
NOTE
The memory card and the software which it contains are needed
to operate the product. Should you wish to replace the memory
card, please copy the contents of the original card onto the new
one using a suitable card reader.
7.3 The boot process
The product has a boot loader, which loads and runs the unit’s
software from the memory card when the unit is powered up. The
indicator for the operating state will light up blue during this. If
there is an error, the indicator will light up red for 5 seconds. After
this the boot loader will automatically be restarted. This will
continue until the firmware can be loaded correctly.
If there is a VT100 compatible terminal connected to the serial
interface, the boot loader prints a status messages to this interface
and the indicator will turn to violett. The terminal adapter must be
configured to 115200 bps, 8 data bits, no parity, 1 stop bit.
NOTE
To identify the terminal adapter, the module will output the byte
sequence „ESC [?1;“during startup with the interface settings
described above. If using the serial interface as command
interface, the host application must be configured in a way that
doesn’t cause any problems when receiveing this byte sequence.
