Front Panel
Switches
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.
Setting the slide switch to the top position assigns ASCII functionality to the port; the
following communication parameters are set and cannot be changed. The following
table shows the ASCII communication port parameters.
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 (refer to the illustration and table that follow) 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 switches.
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
Node Address SW1 SW2
1 ... 9 0 1 ... 9
10 ... 19 1 0 ... 9

50 ... 59 5 0 ... 9
60 ... 64 6 0 ... 4
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.

Modbus
Connector
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.
Modbus Ports
Pinout
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 # 990NAA26320 or
990NAA26350) be used. This cable has been designed to fit under the door of a
Quantum CPU or NOM module.
