•If the unit length of the board is a problem
For a horizontally formatted board, the HSDEC_SEL or H_RCV signal may have been interrupted.
For a vertically formatted board, the VSDEC_SEL or V_RCV signal may have been interrupted.
•When there is a problem within the 8 sensor unit
For a horizontally formatted board, the HSEN_ADR signal may have been interrupted.
For a vertically formatted board, the VSEN_ADR signal may have been interrupted.
•When there is a problem with the 8 LED sensor cycle
For a horizontally formatted board, the HSEN_SEL signal may have been interrupted.
For a vertically formatted board, the VSEN_SEL signal may have been interrupted.
The illustration shows the block diagram of the sensor board (applicable to SEN-H to SEN-N).
For both horizontally and vertically formatted boards, the block structure is the same. If any of the three problems listed below are
encountered, use the checkpoints listed below.
