Chapter 3 OpenWay Riva 500G ERT Module Programming Caution: You must program the 500G ERT module before use. Programming Itron ERT modules requires an understanding of: • Your meter's drive rate and the number of dials ◦ The drive rate and number of dials is important for programming the module to count correctly and roll over to zero at the correct time. For example, a four-dial, 2 cubic-feet meter configuration will count two cubic-feet for each rotation and roll over to zero after 9999.
OpenWay Riva 500G ERT Module Programming Programming the 500G ERT (direct mount) module Program the meter drive rate into the ERT module using a compatible programming device. 1. Verify that you have the correct programming mode (OpenWay Riva Network Mode, or Mobile High-Power Mode, Mobile/Handheld Mode, or Hard-to-read Mobile/Handheld Mode) for your application. 2. For all programming and Check Endpoint operations using a handheld computer, hold the handheld as close to vertical as possible.

OpenWay Riva 500G ERT Module Programming Programming example: Endpoint programmed for 6 dial, 1000 cubic feet CCF. 1. Enter the initial index read. For this example, the initial read is 123456 where 6 = 600 cubic feet. After the initial programming, an endpoint read will result in a reading of 1234560 where the least significant digit is in 10's of cubic feet.
OpenWay Riva 500G ERT Module Programming Note: Itron recommends that users only enable the configurations used by your business unit. Having only one meter configuration option enabled (with the endpoint variable being checked in the FDM business unit) eliminates the need to enter the number of dials. Field Collection System (FCS) (Mobile Mode only) In FCS, a Read Type Code can be assigned to a meter session.
Chapter 4 Specific Meter Manufacturer Installation This chapter provides 500G ERT module installation instructions for the compatible meter types. See each section for a listing of those meters.
