The communication module has a Service LED that
indicates the status of the module itself and the
network. This LED is useful for verifying communication
between the communication module and the
network, and for diagnostic purposes. Table 18 provides
a description of the LED activity. Refer to the LonWorks
Communication Module Installation Manual, IM 927, available
on www.DaikinApplied.com.

Q:
A: The communication module may not be installed properly,
the hardware may be defective, or the LED itself may be
defective.
• Remove the communication module and then re-install it,
making sure the connector snaps into place on all four of
the pins. Use caution as it is easy to either miss just one
• Verify if the BAS recognizes the Neuron ID, even if the
LED is not lit.
• If the communication module is properly installed but
no Neuron ID is broadcast, remove the communication
not function correctly and/or the BAS still does not
recognize the Neuron ID, replace the communication
module.
Q: The BAS does not “see” some or all
A:
it is likely that the BAS is not allowing access to these

Flasher serial cable is connected to the computer.
• Additionally, check that the communications port selected
in the ‘Communications’ section of the ‘Options’ menu is
set to the correct port (i.e. the port to which the Flasher
