The SYS ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red light will
indicate there is a system error on the Simplicity Linc. If this occurs, contact UP Tech Services at 1-877-874-7378
COMM
ERROR
COMM ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady red light will
indicate the communications problem if there is a configured node connected to the Simplicity Linc that is offline.
Config
ERROR
Config ERR LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. A steady amber light will
indicate a configuration error exists in the active configuration. If this occurs, contact UP Tech Services at 1-877-

Node Offline
Node Offline LED will go on solid 15 seconds after power up. It will turn off after 5 seconds. If the Node Offline LED
stays on solid, a node offline condition has occurred.
Unused
15 seconds after powering up the 4 unused LEDs will turn on solid for 5 seconds, then turn off.
RX
On normal operation of Simplicity Linc, the RX LED will flash when a message is received on the field port.
TX
