Front Panel Indicators and Buttons
PWR LED (Green) - Indicates condition of DC input power or a “Wink” command.
 Always On: Correct DC input power is present.
 Flashing Continuously: DC input to module is below minimum required voltage.
 Flashes for 2 Seconds: A “Wink” network management command has been sent to the Control
Neuron Processor.
ERR LED (Red) – Indicates a possible error condition.
 Always On: A diagnostic error has been detected. Press the “RESET” button. If the “ERR” LED now
stays off, the EEPROM contained invalid data and has been reinitialized. Any non-volatile
information must be re-entered by using the NCB/Plug Configuration Plug-in or the DOS NCBCON
program. If the LED stays on solid, a hardware problem is indicated. Contact technical support for
assistance.
 Slow Flash: (once per second) LonWorks configuration information is insufficient. Using a Network
Management Tool, re-commission the internal router nodes (and optionally, the Control Neuron
Processor node).
 Quick Flash: (twice per second) A serial port configured for use (“BAUD” switch set to a value that is
not ‘0’) does not detect an attached modem or is in the process of initializing it. In Ring Mode, this
could also indicate that duplicate Unit Numbers have been detected in the Ring.
ACT LED (Yellow) - Indicates a packet has been passed by the NCB router.
