Inaccurate Timing Issue of PCMCIA-FBUS Series 2 card
When you use PCMCIA-FBUS Series 2 card (rev A) as Link Master and Time Master of the H1 segment, if you connect this segment to NI-FBUS Monitor, you will find the interval between TM (Time Distribution) packets has a slight jitter (about 4%); for example, the interval between two TM packets should be 5 seconds, but if you measure the time-stamp of these two packets from Monitor software, you will find the interval is about 5.2 seconds.
The problem is caused by improper flash ROM settings of the PCMCIA-FBUS Series 2 (rev A) card, which can generate a 4% deviation on clock separation.
The NI PCMCIA-FBUS Series 2 Card Update Utility is developed to solve this problem thoroughly. You can simply refer to the README file and run the utility in your laptop to update the flash ROM settings of PCMCIA-FBUS Series 2 card.
