serve as a pacer trigger for A/D conversions. The counter chip is an
82C54 or its equivalent, which incorporates three 16-bit counters on a
10 MHz clock. One of the three counters is used as an event counter
for input channels or pulse generation. The other two are cascaded
into a 32-bit timer for pacer triggering.
Short Circuit Protection
The MIC-3716 is equipped with short circuit protection device
(polyswitch) on the +12V
power supply pins are shorted to ground (i.e. short circuit occurs), the
protection device will shut off the current output automatically. After
the short circuit has been released for about two minutes, the power
supply pins will return to output current.
Board ID
The MIC-3716 has a built-in DIP switch that helps define each card' s
ID when multiple cards have been installed on the same CompactPCI
system. The board ID function is very useful when users build their
system with multiple MIC-3716 cards. With the correct Board ID
settings, you can easily identify and access each card during hardware
configuration and software programming.
Note:
1. Pace trigger determines how fast A/D conversion will be done in pacer
trigger mode.
