These switches are accessible behind a removable panel, located above the 25-pin connector on the back plate of the camera. Figure 3 illustrates the timing details in Master Mode. Slave Mode is to be selected when the camera’s operations are to be synchro- nized with the user’s unique system. In slave mode, the camera requires an external Master Clock signal (MLCK) to define the output video data rate, as well as a properly timed Line Transfer (LT) signal to initiate the line readout. Figure 4 illustrates timing details in slave mode. Table 1 details correct DIP-switch settings for both Master and Slave Mode. Within slave mode, there are two alternative settings for unique appli- cations. Alternative Slave Mode 1 allows the user to supply the camera with Line Reset (LR) and LT signals, but allows the camera to run at the maximum data rate determined by the internal oscillator. Alternative Slave Mode 2 instructs the camera to ignore LR signals, which allows users to bypass the exposure control feature of the camera. Table 1 details all DIP- switch settings for all operating modes. 12586 Final Art 2 5/9/01 4:51 PM Page 3 |
