Removable Media Troubleshooting
Description
Action
XL7 OCS does not read media card. The media card should be formatted with the XL7 OCS.
XL7 OCS will not download project
file.
Make sure the project file is saved as a .pgm file and
not a .csp file. In addition, to file must be .pgm, the
file's I/O configuration must match the XL7
configuration for it to download.
23.5 USB Interfaces
•
Plugging and unplugging USB devices while the OCS is powered up can cause the OCS
to reset. In general, branded USB memory sticks will not cause this problem, however,
with the advent of USB 3.0 and larger / faster memory devices this cannot be
guaranteed.
•
Larger USB devices such as hard-drives etc. should only be attached and removed
when the OCS is powered down.
•
The resets are caused by short sharp current spikes when devices are added or
removed from the OCS, these spikes can exceed the USB specification but are usually
very short and mostly do not cause problems. Some devices however draw a longer
larger current as they power up causing a brief dip in the OCS internal supplies leading
to a reset.
•
Standard SanDisk and Kingston ranges with read times less than 120MB/sec. should
not cause resets. The display will flicker when a device is added or removed.
