H901CIUA Board Description

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

Functional Specifications

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

Parent Topic: Universal Interface Board (GPIO)

Working Principle

Figure 2 Working principle of the H901CIUA board



Indicates the control signal channel.



Indicates the service signal channel.



Control module: manages the entire board and the service boards, and communicates with the fan tray through the extended serial port.



  • Ethernet physical layer module: provides the GE transparent transmission port.

  • BITS clock module: recovers the 2 Mbit/s clock signals or shapes the 2 MHz clock signals, which can function as the system clock source.

  • Digital parameters detection module: detects the statue of the digital parameters of the environment monitor device.



Indicates the power or clock signal channel.



  • The power module supplies power to each functional module of the board.

  • The clock module provides clock signals for each functional module of the board.
