The H901CIUA board is a general interface board. It provides the input and output clock source for the system and supports functions such as input and output of alarm digital parameters.
Figure 1 Appearance
The H901CIUA board supports the following functions:
7 inputs of alarm digital parameters and 1 output of digital controlling parameters
2 inputs of 2 Mbit/s or 2 MHz BITS clock signals
2 inputs of 1PPS+TOD time signals
1 output of 2 Mbit/s or 2 MHz clock signals
1 output of 1PPS+TOD time signals
External monitoring Ethernet port to transparently transmit monitored data
