中间和底部位置的保护。上的三位滑动开关
右侧用于选择Modbus（RS232）端口的通信参数设置。
下图显示了CPU11302可用的三个选项。
将滑动开关设置到顶部位置将ASCII功能分配给端口；这个
以下通信参数已设置且无法更改。
将滑动开关设置到中间位置将分配远程终端单元（RTU）
端口的功能；设置了以下通信参数，但无法：
被改变。
注：当前面板开关处于以下状态时，CPU硬件默认为桥接模式
设置为RTU或ASCII模式。连接控制器时，面板设备连接

Two, three-position slide switches are located on the front of the CPU. The left
switch is used for memory protection when in the top position and no memory
protection in the middle and bottom positions. The three-position slide switch on the
right is used to select the communication parameter settings for the Modbus (RS232) ports.
The following figure shows the three options that are available for the CPU11302.
Setting the slide switch to the top position assigns ASCII functionality to the port; the
following communication parameters are set and cannot be changed.
Setting the slide switch to the middle position assigns remote terminal unit (RTU)
functionality to the port; the following communication parameters are set and cannot
be changed.
Note: The CPU hardware defaults to bridge mode when the front panel switch is
set to RTU or ASCII mode. When networking controllers, a panel device connected
to the CPU Modbus port can communicate with the controller to which it is
connected, as well as log into any nodes on the Modbus Plus network.

Rear Panel
Switches
Two rotary switches are located on the rear panel of the CPU. They are used for
setting the Modbus Plus node and Modbus port addresses.
SW1 (the top switch) sets the upper digit (tens) of the address; SW2 (the bottom
switch) sets the lower digit (ones) of the address. The illustration below shows the
correct setting for an example address of 11.
The following figure shows SW1 and SW2.
The following table shows the SW1 and SW2 address settings.
Note: The highest address that may be set with these switches is 64.
SW1 and SW2 Address Settings

Note: If "0" or an address greater than 64 is selected, the Modbus + LED will be
"on" steady, to indicate the selection of an invalid address.

Pinouts
All Quantum CPUs are equipped with a nine-pin RS-232C connector that supports
Modicon’s proprietary Modbus communication protocol. The following is the Modbus
port pinout connections for nine-pin and 25-pin connections.

Connections
The following figure shows the Modbus port pinout connections for nine-pin and 25-
pin connections.
Note: Although the Modbus ports electrically support existing Modbus cables, it is
recommended that a Modbus programming cable (Part # 990NAA2620 or
990NAA26350) be used. This cable has been designed to fit under the door of a
Quantum CPU or NOM module.
