Sumario:Read-out boards (ROB) are one of the key elements of readout system for CMS barrel muon drift chambers. To insure proper and reliable operation under all detector environmental conditions an exhaustive set of tests have been developed and performed on the 30 pre-series ROB's before production starts. These tests include operation under CMS radiation conditions to detect and estimate SEU rates, validation with real chamber signals and trigger rates, studies of time resolution and linearity, crosstalk analysis, track pattern generation for calibration and on-line tests, and temperature cycling to uncover marginal conditions. We present the status of the ROB and tests results. (5 refs).
