5.1 Host Link issues
During the DSTREAM-XT system boot sequence, the LEDs identify the progress of the boot
sequence. On the XT probe, to indicate that the units are successfully linked, the
Host Link
LED
briefly flashes
blue
, then illuminates
green
.
If the
Host Link
LED fails to illuminate
green
, the link connection has not been established.
Host Link LED fails to illuminate green
If the
Host Link
LED does not illuminate
green
within 12 seconds, the link connection is
incomplete. This might be due to one or more of the following reasons:
• The XT probe factory firmware version requires updating.
• The flash memory on the XT probe is corrupt. If the flash memory is the cause, the
STATUS
LED illuminates
red
.
• The connection of the AUX 60-way ribbon cable is not complete.
Solution
1. Disconnect the AUX 60-way ribbon cable.
2. Ensure the Aux connector pins on the DSTREAM-ST unit and XT probe are not damaged.
3. Ensure the 60-way ribbon cable is not damaged.
4. Reconnect the 60-way ribbon cable. Ensure both ends of the cable are securely connected.
5. Reset the DSTREAM-XT system. Use the reset button on the rear of the DSTREAM-ST unit.
6. If a reset does not fix the
Host Link
connection, restore the DSTREAM-XT system. For more
