TDC-0909-003 100W and 100WP Datalogging ERT Module Installation Guide 10
Proprietary and Confidential
100W Encoder Start-up
The 100W automatically:
• Detects the connected register type at the top of the hour, exits Factory mode, and enters Run mode
(programming is not required for the 100W to initiate Run mode in the default Mobile mode).
• Detects an Itron Leak Sensor.
100W encoder programming is required to:
• Change the operation mode (for example, to change the ERT module from the default Mobile mode to
Fixed Network mode).
• Enter a Utility ID or Lock Type.
• To enter an E-Coder 8-digit driver.
Itron strongly recommends performing a Check ERT with a handheld computer running FDM to verify the
ERT module is operating correctly after installation. Performing a Check ERT will:
• Generate an immediate register read.
• Align the 100W's time with the handheld's time.
Important Periodically dock or cradle the handheld computer or Mobile Reader to keep the time
current.
• Verify communication with the Leak Sensor.
• Check for tamper flags.
Programming the 100WP
Programming the 100WP requires one of the following handheld computers running Field Deployment
Manager (FDM) version 1.0 or later.
• FC200SR handheld computer (Itron part number FC2-0005-004 or FC2-0006-004)
• FC300 with SRead
For normal activation, connect the 100WP to the water meter register and program the ERT module with
FDM.
