Compatibility: VMEbus specification-compatible double height form factor During on-line operations, the relay drivers are active and the read-back feature of the output registers is Built-in-Test Features: This board is designed with disabled. In this condition, when data is read back from internal logic that contains the state of each relay coil. the board, it is inverted. For example, when a logic one is This data can be read by the host during on-line or written to a positive true board, the data read back will be off-line operations to monitor the condition of the board. a logic zero because the driver inverts its input data. The The data read back by the host will depend upon the logic levels are reversed for negative true boards. Here a board’s mode of operation. zero is written to activate a relay and a logic one will be read back. During off-line operations, the test mode is active.
