FAQ

1. Q: Can Ramix PMC422FP work on non-PMC standard slots?
   A: It is PMC mezzanine card, must be installed on host board with PMC slot, cannot be used directly on PCI slot.
2. Q: What are typical card failure symptoms?
   A: Partial or all serial ports no response, data packet loss, PMC bus communication failure, port cannot receive/transmit data.
3. Q: How to complete commissioning and diagnosis?
   A: Insert card into PMC slot, power on, install driver, connect serial devices and test data send & receive of each channel.
