X64 Xcelera-HS PX8 User's Manual
J9: Board Sync
Interconnects multiple X64 Xcelera boards to synchronize acquisitions to one trigger or event. The
trigger source can be either an external signal or internal software trigger. The board receiving the
trigger is the Master board. while the boards receiving the control signal from the Master board are
Slaves.
Hardware Connection: Interconnect two, three, or four X64 Xcelera boards via their J9
connector. The 4 pin cable is wired one to one — i.e. no crossed wires. The cable must be as
short as possible and the boards must be in the same system.
Master Board Software Setup: Choose one X64 Xcelera as master. The Sapera parameter
CORACQ_PRM_EXT_TRIGGER_SOURCE is set to either Mode 1–Output to Board Sync or Mode
2–Control pulse to Board Sync. See Sapera documentation for more details.
Slave Board Software Setup: The Sapera parameter CORACQ_PRM_EXT_TRIGGER_SOURCE
is set to From Board Sync.
Test Setup: The control application starts the acquisition on all slave boards. The acquisition
process is now waiting for the control signal from the master board. The master board
acquisition is triggered and the acquisition start signal is sent to each slave board (with ~0.8μs
delay max).
