To: Randy Clark From: Jon Mueller (Itron, Inc.) Date: 11/06/07 Re: Description of changes from ERG-5000-001,002, 003, 004, to ERG-5000-007, 008. Summary Itron is in the process of rolling out the 100G product line. Currently, we have the first 6 models of endpoints released (p/n’s: ERG-5000-001,2,3,4,5&6) under FCC ID: EO9100G and IC: 864D-100G. We wish to add the next 2 models in the 100G rollout (p/n’s: ERG-5000-007&8) to the family, and use the same FCC and IC identification numbers. Differences Like the 40GB product line, the 100G comes in different mechanical packages, in order to attach to different gas meters. In the case of the first 4 models released, the same circuit board is used by all models. In the case of the -007 & -008 models, the PCB layout is identical; however, a different tamper switch is used on the circuit board, due to mounting the board in a horizontal position (as opposed to vertical). This switch detects tamper and has leads that allow it to remain vertical when the circuit is in a horizontal position. The plastic housings are different, as is the case with all models, but the most noticeable difference when looking at the inside of the unit, is the addition of a metallic piece. This bronze metallic piece is added to these two models to correct the polarization of the unit. This is due to the board being contained in the housing in a horizontal position. In the previous models, the circuit is mounted in the housings in a vertical position. This metallic piece is added to correct the polarization only, it does not further enhance the signal strength (relative to previous models), which is evident in the emissions report that is also provided. For FCC purposes, I wish to address this by means of a Class 2 permissive change. For IC purposes, I wish to add these 2 new part numbers to the 100G family. Itron Confidential
