7. No Ethernet communication can be established
If it is not possible to communicate with BioMax2 / KBio2-Online via Ethernet, try
the following:
- Check the status of the red ETH_LINK LED, next to the Ethernet connector
- If the LED is off, physical link has been established. Then, make sure that there is
no duplicate IP address, and that IP configuration is correct. It should be
possible to contact the electronics board by means of the KSearch application,
at least when the Broadcast response is selected.
If the ETH_LINK LED is on, the physical link could not be achieved. Then:
- Try replacing the Ethernet cable, or check the Ethernet switch status.
- If BioMax2 / KBio2-Online was connected at 100 Base-T and then we try a 10
Base-T connection (or viceversa), try with a hard reset of the electronics.
- If the LAN is NOT Gigabit Ethernet compatible, we may restrict negotiation
options by activating bit 4 (add $10) on parameter CFG_ePHY (See Table 11 in
Subsection 8.2.1.).
- We may choose to reconfigure parameter CFG_ePHY to value $07, so that a full
re-negotiation starts with the Ethernet switch (after hard-reset).
