The software controls the routing of these signals to/from the connectors on the rear panel through the Sync. Input Signals and Sync. Output Signals properties. Note The BSA F/P50, F/P60 and F/P80 processors requires the 62N560 Synchronisation option to make use of these inputs and outputs The synchronisation input connectors are the three BNC connectors named Programmable Input 1, 2 and 3, and the 25-pin D-sub connector underneath these as shown on the figures below. The Optional Input connector is reserved for future extensions of functionality. BNC connectors for TTL level inputs Figure 6-36 The synchronisation input and output connectors on the BSA The pin numbering of S1 and assignments are shown in Figure 6-37 and Table 6-3. Please note that some of the pins are assigned to Sync outputs which are described in the next section. Figure 6-37 Pin numbering on the S1 connector Shutter output for PDA BNC connector for TTL level outputs S1 Connector: 25 pin D-sub connector for SYNC inputs and outputs S2 Connector: 9 pin D-sub connector for Analog Monitor option 6-34 BSA Flow Software: Options and Add-ons

Input Signals properties Table 6-3 Pin assignments on the S1 connector Cyclic phenomena data can be sorted either according to the time passed from the last reset, or according to the physical angle of rotation of an encoder. To sort according to time, use the Sync. 1 for a reset pulse (once per cycle pulse) . Bursts will be stamped with the time from the last Sync. 1 pulse. To sort according to physical angle using an encoder, use Reset Encoder and Encoder. Bursts will be stamped with the encoder count from the last Reset Encoder pulse. It is possible to map the same inputs both to the Sync.1, Sync. 2 and to the Reset Encoder and Encoder inputs. In this case, each burst will have an arrival time and an encoder count associated, and each Sync pulse will be time stamped. BSA Flow Software:Options and Add-ons 6-35
