Hardware Platforms
The 460 Product Line supports a number of different hardware platforms. There are differences in how
they are powered, what serial settings are supported, and some diagnostic features supported (such as
LEDs). For these sections, be sure to identify the hardware platform you are using.
To find which hardware platform you are using:
1) Look on the front or back label of the unit for the part number.
2) On the webpage inside the gateway, navigate to the dropdown menu under Other and select
Utilities. Click the Listing of Revisions button. The full part number is displayed here.
Once you have the full part number, the platform will be the number following the “-N”:

Accessing the Main Page
The following steps will help you access the browser based configuration of the gateway. By default,
DHCP is enabled. If the gateway fails to obtain an IP address over DHCP it will Auto IP with 169.254.X.Y.
1) Insert the provided CD-ROM into a computer also on the network.
2) Run the IPSetup.exe program from the CD-ROM.
3) Find unit under “Select a Unit”.
a. Change Gateway’s IP address to match that of your PC if DHCP has failed.
i. You will know DHCP has failed if the gateway’s IP address is AutoIP at
169.254.X.Y.
ii. If successful, it will say DHCP’d at ex: 192.168.0.100 or however your DCHP
Client is set up.
b. If you do not see the gateway in this tool, then your PC is most likely set up as a static IP.
i. Change your PC’s network settings to be DHCP. If DHCP fails, then it will change
to be on the 169.254.x.y network.
ii. Relaunch the IP Setup tool to see if gateway can be discovered now.
4) Click Launch Webpage. The Main page should appear.
Default setting is set to DHCP. If DHCP fails, default IP Address is 169.254.x.y

Error: Main Page Does Not Launch
If the Main Page does not launch, please verify the following:
1) Check that the PC is set for a valid IP Address
a. Open a MS-DOS Command Prompt
b. Type “ipconfig” and press enter
c. Note the PC’s IP Address, Subnet, and Default Gateway
2) The gateway must be on the same Network/Subnet as the PC whether it’s setup for DHCP or
Static.
Once you have both devices on the same network, you should be able to ping the gateway using a MS-
DOS Command Prompt.
The Screenshot above shows a gateway that is currently set to a static IP Address of 192.168.0.100.
If you are able to successfully ping your gateway, open a browser and try to view the main page of the
gateway by entering the IP Address of the gateway as the URL.

Committing Changes to the Settings
•All changes made to the settings of the gateway in Configuration Mode will not take effect until the
gateway is restarted via the webpage. Changes will not be stored if the gateway’s power is removed
prior to a reboot.
•NOTE: The gateway does not need to be restarted after every change. Multiple changes can be
made before a restart, but they will not be committed until the gateway is restarted.
•When all desired changes have been made, press the Restart Now button.
•The webpage will redirect to our rebooting page shown below:
•The reboot can take up to 20 seconds. You will know the save was successful if the red box is no
longer present.
oIf the IP address has not been modified, the gateway will automatically redirect to the
main page.
oIf the IP address was modified, a message will appear at the top of the page to instruct
the user to manually open a new webpage at that new IP.

Main Page
The main page is where important information about your gateway and its connections are displayed.
Mode (orange box below):
Running Mode:
-Protocol communications are enabled
-Configuration cannot be changed during Running Mode. If changes are needed, click
the Configuration Mode button shown in the green box below
Configuring Mode:
-Protocol communication is stopped and no data is transmitted
-Configuration is allowed
Navigation (green box below):
You can easily switch between modes and navigate between pages (Configuration, Diagnostics,
and Other pages) using the buttons on the left hand side.

Device Configuration
The device configuration area is where you assign the device description paramter. Changes can only be
made when the gateway is in Configuration Mode.
Once you are done configuring the Description, click the Save Parameters button.

Network Configuration
The network configuration area is where you assign the IP address and other network parameters.
Changes can only be made when the gateway is in Configuration Mode.
Once you are done configuringthe Network Settings, click the Save Parameters button.
If you are changing the IP Address of the gateway, the change will not take effect until the unit has been
rebooted. After reboot, you must enter the new IP Address into the URL.
It is recommended to leave the DNS Gateway set to 0.0.0.0 and the Ethernet Link as
Auto-Negotiate. If configuring the gateway to use E-mail, the DNS Gateway must be
set.

Modbus RTU Master Configuration
Click the Modbus RTU Master button to access the configuration page.
1) Serial Port: Select which serial port is being used for communication. This port must be
configured on the Port Configuration page. If it has not yet been configured, it will display
Disabled after the Port descriptions in this dropdown.
2) Delay Between Messages: Enter the length of time to delay between read and write scan line
requests (ms).
3) Response Timeout: Enter the amount of time the gateway should wait before a timeout is
issued for a read/write request (ms).
4) Dependency Protocol: If enabled, Modbus RTU Master communication will stop if
communication to the selected protocol is lost.

Modbus RTU Master Device Configuration
The bottom area of the Modbus RTU Master Configuration page lets you configure up to 32 external
Modbus RTU Slave devices.
1) To add additional Slave connections, click the -Select- dropdown under Modbus RTU Master
Device List and select Add Generic Slave option.
-To remove a device, navigate to the slave to delete using the << and >> buttons and click
the Delete Slave button.
-To create a new slave with the same parameters already configured from another slave,
click the -Select- dropdown and select the Add from Modbus RTU X option (where X
represents the slave you wish to copy parameters from). Once created, you can make any
additional changes needed to that new slave.
2) The Enable check box should be selected for the device.
3) Enter a Device Label to identify the device within the gateway.
4) Enter a unique Modbus RTU Slave Address for the device on the network.
5) Force Function Code 15/16 for Single Writes: Only select this if the Modbus RTU device does
not support Modbus Function Code 5/6.
6) Enable 0-Based Addressing: Check ONLY if the Slave you are connecting to begins their register
numbering at 0 OR they specify that their device addresses are 0-based.

7) Bit Pack: Select the formatting of the Coil Status/Input Status. Automap will use this packing size
to map coils to/from the other protocol. The bit pack selection here should match that of the
other protocol. The starting address is considered Bit 0 and is the low-order bit.
8) Enable Modbus ASCII: Only select this if your Modbus device is also using ASCII messaging. By
default, the device will use Modbus RTU.
9) To enable data swapping, select the required Swap Indicator. If the bytes appear in the wrong
order, enable swapping to change the data. This swapping does NOT change Coils and their
ordering inside the Bit Pack.
10) Enter the number of Read Scan Lines and Write Scan Lines.
11) Click the Generate Scan Lines button to have the read and write scan lines auto-generate for
you. You may manually configure the read and write scan lines after they have been generated.

Configuring Read Scan Lines
Follow these steps to manually configure Read Scan Lines.
1) Select View Read Scan Lines if not already selected.
2) Select a Point Type for each Scan Line. Options include: Coil Status, Input Status, Input Registers,
and Holding Registers. Note: Input/Holding Registers also have a data type associated with
them.
a. String Point Type- If the mating protocol supports strings, you may select string as a
point type in Modbus. With this point type, 2 characters will be packed into a single
register and the first register will be set aside for the length.
EX: 4x Hold Reg (String) with a Starting Address of 1 for a length of 5 Registers
This means that Register 1 will hold the length of the string and Registers 2-5 will hold
the string contents. This string can contain a max of 8 characters.
3) Enter a Starting Address (This will be 1 based if Enable 0-Base Addressing is unchecked, or 0
based if checked).
4) Enter the # of consecutive points to read for that point/data type. See the Scan Line Data Limit
section at the bottom of the webpage for max values in a scan line.
