10.3 LCD Message Codes

These message codes display on the device's LCD.
Message Solution
BAD EE System Error. A system error typically represents a failure of the EE PROM. Contact the factory for replacement.
EC XX The XX refers to the Modbus register 8 message code shown in
78. The LCD displays the message code in decimal; host-controlled systems read the 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 GatewayPro 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
Message Codes for Register 8
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
No LCD 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.
• Battery-powered devices turn off the LCD after 15 minutes (factory default). Push any button to reactivate
the LCD. Battery-powered devices may be in storage mode. To put battery powered devices into storage
mode, hold button 1 for 5 seconds. To return from storage mode, hold button 1 for 5 seconds.
• Recheck the power connections and power requirements. Battery-powered devices require 3.6 to 5.5 V dc.
Non-battery powered devices require 10 to 30 V dc.
• After replacing the battery, allow up to sixty seconds for the device to power up.

10.3.1 Modbus Message Codes for Register 8

Register I/O 8 is reserved for device messages or Site Survey data when in Site Survey mode.
Conditions are detected as they occur and are reported to the Gateway. After the message is sent to the Gateway, the
Node does not resend the message until the condition changes or there is a higher priority message. The higher the
message code, the higher the priority. For more information about how Site Survey data is stored in registers 7 and 8,
refer to Conducting a Site Survey (Gateway and Nodes)
The following are the Modbus message codes, shown in hex, that may appear on the SureCross devices' I/O 8 Modbus
register.

Description
Normal operation. Device message register contents 0x0080 indicate the Node is synchronized
to the Gateway. (Decimal value 128.) A value of zero (0) indicates there is no device present.
Unknown message. The message was received correctly (correct checksum), but it is not a
recognized command. This type of message is usually caused by devices with poor radio links
or collocated networks that are not uniquely separated by binding codes and Network IDs.
Network performance is not affected. (Decimal values 256 through 511.)
Radio Device (polling/heartbeat) Timeout. (Decimal value 13569.) A Node dropped out of the
wireless network based on the polling or heartbeat parameters. Refer to the User Configuration
Tool documentation for polling or heartbeat parameters and the timeout operation. When the
least significant bit is on (1), an error condition exists.
• Run a site survey to determine the quality of the radio link. If no communication exists
between the Gateway and Node, verify the power at the Node and all antenna
connections. Blocked radio communications may also be a result of recently changed
environmental conditions.
• Replace the battery of a battery-powered Node. Although the LCD and device may
appear functional, the battery may not have enough capacity to handle radio
communication.
Modbus time-out. A Gateway timeout (inactivity on the serial channel) was detected. (Decimal
value 13825.) When the least significant bit is on (1), an error condition exists.
Modbus register 8 device messages are disabled. The Modbus register 8 clears or disables
messages using the Gateway's Modbus register 15. (Decimal values 65024 through 65279.)
