If data was not generated by the local node, it is placed in the receive FIFO. The receive FIFO then places data in RAM and into the transmit FIFO to be sent to the next node on the link. Data can be mixed from the local VME and the link based on which arrives at what time. Just because two data transfers arrive in one node back-to-back does not guarantee a transfer cannot be inserted between them by the local VME card. Priority is given to the local VME card in case of a simultaneous access to the RAM and the transmit FIFO by the local VME and the receive FIFO. In any other case, the other must wait for the current cycle to finish to gain access to the RAM.
IACK DAISY CHAIN
If there are empty slots to the left of the VMIVME-5576, then IACK Jumpers must be installed for the empty slots. Otherwise, the VMIVME-5576 will intermittently fail to respond to VMEbus reads and writes.This section of the technical manual provides information relative to the care and maintenance of VMIC’s products. Should the products malfunction, the user should verify the following: a. Software b. System configuration c. Electrical connections d. Jumper or configuration options e. Boards fully inserted into their proper connector location f. Connector pins are clean and free from contamination g. No components of adjacent boards are disturbed when inserting or removing the board from the VMEbus card cage h. Quality of cables and I/O connections
