7. Double-click Gateway push button 2 to return to the Device Configuration (*DVCFG) menu.
8. Click Gateway push button 1 until reaching the *RUN menu option.
5.10.3 Set the Parity
Parity bits are used to detect errors in data.
1. Single-click button 1 to advance between menus. Stop when you reach the DVCFG menu.
2. Press button 2 once at the *DVCFG menu to enter the Device Configuration menu.
3. Press button 1 to advance through the items in the *DVCFG menu. Stop advancing when you've reached the setting
for the PARITY.
4. Single-click Gateway push button 2 to display the current setting. Single-click Gateway push button 1 to cycle
through the available options. Stop on the desired setting.
The options are NONE, EVEN, ODD. The factory default is NONE.
5. Single-click Gateway push button 2 to save the new setting.
6. If using a network ID (NID), adjust both rotary switches back to the NID value.
To avoid losing the network connection between the Gateway and Nodes, reset the rotary switches back to their
appropriate values before leaving the *DVCFG sub-menus. If the Gateway and Nodes lose their connection, the
network may take up to 20 seconds to re-synchronize.

5.11 Default Output Conditions
The timeout structure of the SureCross wireless network sets relevant outputs to user-defined conditions when radio or
host communications fail.
If the timeout features are enabled, the outputs are set to default states or the last known state before the error. The timeout
error conditions are cleared by either a reset command sent from the host, using the front panel display, or using the auto-
recover feature. Communications timeouts occur in three areas within the SureCross wireless system:
• Host Link Failure to the Gateway (Modbus Timeout)
• Gateway Link Failure with any Node
• Node Link Failure with the Gateway
5.11.1 Host Link Failure
A Host Link Failure occurs when the defined timeout period, typically about four seconds, elapses with no communication
between the host system (or Modbus master device) and the DX80 Gateway.
