Chapter 3 Hardware Structure and Operation Theory
NR ELECTRIC CO., LTD. 10
NOTE: The above 2 figures are only examples to show the hardware structure of
RCS-9698G/H . Please refer to corresponding contracts and technical schemes for
hardware configuration.
Each equipment rack can be equipped wi th the following modules:

Motherboard : This board provides connections for various boards of the equipment.

CPU board (on the 2nd, 3rd, 4th and/or 5th (optional) slot). As a central processing unit
and communications board based on distributed multiple CPU structure, main
components and functions of the equipment are included in this board, such as CPU
system, Ethernet port and serial port management and so on.

Serial port extension board (on the 5th (optional), 6th and 7th slot): this board provides
four insulated serial links. When the COM board is installed in the 7th slot, it can provide
1 GPS input interface and hard-wired ports for dual system switchover.
COM board can be equipped in the 5th (optional), 6th or 7th slot, but MDM board can
only be equipped in the 5th (optional), 6th slot. Slot 7 can only be equipped with COM
board.

PWR board (on the 1st slot). This board includes auxiliary power supply DC/DC
converter, four binary outputs and four binary inputs.

HMI board : This is for local man machine interface (MMI) management, including LCD ,
keypad, LED indicators, alarm circuit, etc.
3.2 Basic Enclosure
The basic enclosure for the equipment is an electronic equipment rack with an adequate number
of slots for the CPU board, serial port extension board and PWR board. The basic rack is
equipped with a motherboard. The mother board provides some motherboard lines for distributing
signals within the enclosure.
There are 7 slots in the rack of a single machine, which can be populated with the boards such as
CPU board, serial port extension board( COM board or MDM board) and PWR board. Typical
allocation of the slots is showed in the following figure.
