Have a stand alone 75 ton RTU with a LCI-I Lon-Talk comm. interface, all com. lights ok on LCI-I board except for red service light flashing every second. Indicates LCI- I is unconfigured. Intergrating with Honeywell WEBS AX. Have A Jace 600 and 30 xl10 vav controllers. Tried all different ways to discover the LCI-I and no luck. Started a new station hooked up directly and tried different Domain Id and length. No problem communicated to xl10.
