Message
BAD EE

replacement.
EC XX
The XX refers to the Modbus register 8 message code shown in
Register
message codes in hex.
DX80 display shows *ERROR: The Gateway uses fully-acknowledged polling to ensure each Node
radio link is robust. If a prescribed number of sequential polling cycles are not acknowledged by a
Node, the Gateway considers the radio link with that Node to be timed out. All outputs on the Node in
question are set to the user-selected default state or the output holds its last state, depending on
user configuration options set using the User Configuration Tool. If the Node's radio link recovers
and the Gateway or Gateway Pro determines enough acknowledged polling messages have
accumulated, the link is reinstated.
EC 53
Radio Device (polling/heartbeat) Timeout. (Decimal value 13569.) A Node dropped out of the
wireless network based on the parameters defined for polling or heartbeat. For more information,
see Message Code 35 in
EC 54
Modbus time-out. A Gateway timeout (time of inactivity on the serial channel) was detected. For more
information, see Message Code 36 in

All DX80s display "POWER" on the LCD for the first 5 to 10 seconds after applying power. A
Gateway's LED 1 is solid green when power is connected. Nodes flash a red LED 2 every 3 seconds
or a green LED 1 every second depending on the radio link status.
