A first row of optically transparent (132) and non-transparent positions forms a calibration code pattern (130) disposed within a first area of the port-insertion region (126). A second row of optically transparent (142) and non-transparent positions forms a synchronization code pattern (140) disposed within a second area of the port-insertion region (126). The second area is different from the first area. The synchronization code pattern (140) corresponds to the calibration code pattern (130) such that the synchronization code pattern (140) provides synchronization of the serial calibration code pattern (130) during insertion of the port-insertion region (126) into the receiving port of the analyte meter.
