Introduction
This manual is intended to provide a description of the Calmotion LANCNC-FAD FTP
file server for Fadal CNC’s. Some knowledge of LAN is required to setup the device onto
a network. Some examples of possible network scenarios are provide later in this
manual.
Requirements
The LANCNC-FAD device will work with any Fadal CNC control versions with an
available DB25 serial connection located at the back of the machine. +12VDC will be
required for the device. This can be acquired from the Fadal power supply. Only service
personnel with appropriate knowledge should install this device. Calling a local Fadal
distributor to help install is not required, but recommended.
Installation
1. Power off machine.
2. Connect the power plug to +12 volts in the electrical cabinet. The white-stripped
wire must be connected to +12 volts and the solid black wire connected to ground.
If possible, label the wires for future reference.
3. Locate a position for the Din rail.
4. Mount the LANCNC-FAD board to the din rail using the supplied clips.
5. Route CAT5 cable into the electrical cabinet.
6. With the black power unplugged from the LANCNC, check the power at the plug
end. The inside sleeve should be +12 volts and the outside sleeve of the plug
should be ground. Do not proceed unless the proper polarity has been established.
7. Plug in the power to the LANCNC-FAD. A green power light should light up.
8. Plug the CAT5 Ethernet cable into the LANCNC-FAD.
9. Install the SD card into the LANCNC.
10. Plug the DB25 cable coming from the Fadal CNC into the LANCNC.
11. At ENTER NEXT COMMAND, execute the INI+ command. See the command
section below. Verify that the communication to the Fadal CNC is in working
order before continuing.
12. Set up network as desired to connect to the LANCNC FTP server.

Description of Operation
The LANCNC-FAD acts as an FTP server for file storage that in turn can be accessed by
a Fadal CNC. Connection to the FTP server can be done with standard software tools that
are provided with most PC’s. A logon is not required as the LANCNC FTP server
accepts anonymous logins. Special software is not required. The most popular of these
are Explorer and Internet Explorer from Microsoft. Anyone on the network can drag and
drop files to the CNC server where they can be transferred to machine memory or drip
fed (DNC). Conversely, files residing in CNC memory can be sent to the data server
where they can be accessed by anyone on the network.
File information is stored on an SD card resident on the LANCNC-FAD. A 1 GB or
greater SD card is provided as standard. Other sizes may be substituted. In the event of a
network outage, the SD card may be removed and inserted into a PC. Files can be added
or stored at the PC and replaced in the LANCNC-FAD.
Note: Files should follow the 8.3 format for proper operation. E.g. File name should not
exceed 8 characters and the suffix should not exceed 3 characters.
The operator interface to the data server on the CNC side is done on the pendant of the
Fadal CNC. Special ‘+’ commands are used to active the data server on the CNC side.
The correct CD,# must be used for proper operation.
The CNC command CD,8 sets a baud rate of 9600 to the LANCNC-FAD.
The CNC command CD,10 sets a baud rate of 38400 to the LANCNC-FAD.
The CNC command CD,11 sets a baud rate of 57600 to the LANCNC-FAD.
(The above assumes that the version of Fadal control supports the baud rates listed.)
Once a CD command is entered, a LANCNC-FAD plus command may be used. A plus
command activates the LANCNC-FAD device and allows it to take control of the CNC
machine. When the command is finished, the LANCNC-FAD will issue a BYE command
to the machine. Another CD,# will be needed before another plus command can be sent
to the LANCNC-FAD device. The following demonstrates the order of operation to
execute a LANCNC-FAD command:
1. Enter the CD, Change Device, command for the LANCNC-FAD connected to
machine (example: CD,10 CD,11 or CD,8).
2. Type in the LANCNC-FAD command desired, ending the entry with a + sign and
not a carriage return (enter key).
3. Wait for command to be processed (a couple of seconds if a SD card has just
inserted).
4. Command is finished after the BYE command.

Example of Use
The LANCNC-FAD utilizes a new set of commands that are based on existing Fadal
commands. These new commands are called “plus” commands. These new commands
are called plus commands because a + is used at the end of the commands to tell the
LANCNC-FAD device to operate on these commands. The enter key is not used at the
end of the LANCNC-FAD commands.

Deciding on a network configuration
There are several ways to design a network. Some knowledge and experience with setting
up networks is highly suggested. The simplest example shown below is of a peer-to-peer
network where there are only two devices connected. The other examples shown below
expand the number of computers and LANCNC possible on the network.
Using the simple peer-to-peer network is a good starting point when setting up a new
network or before integrating the LANCNC and Fadal CNC into a larger company
network.
The following are the suggested manufacturers of routers and access points:
Belkin 4-Port Cable/DSL Gateway Router F5D5231-4
Belkin Wireless G Router F5D7230-4 (this can be configured as an access point)
Belkin Wireless G Router P57612-G (this can be configured as an access point)
Example 1, Simple Peer-to-peer Network connection to the LANCNC-FAD
The diagram below shows a simple peer-to-peer configuration of integrating a computer
(i.e. desktop or laptop computer running Windows, MAC or Linux OS), the Calmotion
LANCNC controller and a Fadal CNC. This simple setup is good starting point when
setting up a new network or before integrating it into a larger company network.

The figure above shows the display on a PC when the ftp site has been opened from the
previous step. At this screen, files can transferred from any file folder on your PC and the
FTP site. If you wish to create a new directory on the FTP site, create a file folder
somewhere on your PC such as “My Documents”. Select the folder and drag and drop
with your mouse to the ftp window shown above. The file directory as well as any files
inside the directory will be copied to the LANCNC-FAD ftp site.
As an alternate, there are a number of ftp software programs that are available that offer
additional ftp options for managing your files. Additional features offered are logging
file transfer activity, data rate transfer, and comparisons of directory data.

The IP address of the router is required to setup the LANCNC. There maybe some
changes on the router also. The following are the suggested settings on the router:
DHCP enabled (On)
IP Address: 192.168.2.1
Subnet Mask 255.255.255.0
IP Pool Starting Address 192.168.2.2
IP Pool Ending Address 192.168.2.100
Using these settings on the router will allow computers on the network to automatically
get their own IP addresses in the range of 192.168.2.2 to 192.168.2.100. And it leaves
192.168.2.101 and above to be available to static IP address like the LANCNC devices.
It is important to note that only one device can use an IP address at a time. The router,
computers, printers, and LANCNC devices need to have their own number in the network
range provided by the IP address and Subnet Mask. In the suggested settings above the
only address available to the network devices is between 192.168.2.1 and 192.168.2.254.
The following is and example of IP addresses that could exist:
192.168.2.1 is the Belkin Routers IP address (fixed in the router settings)
192.168.2.2 is a desktop computer IP address (automatically provided by the DHCP)
192.168.2.3 is a laptop computer IP address (automatically provided by the DHCP)
192.168.2.4 is a printer IP address (automatically provided by the DHCP)
192.168.2.101 is a Calmotion LANCNC IP address (set in LANCNC.INI on the SD card)
192.168.2.102 is a Calmotion LANCNC IP address (set in LANCNC.INI on the SD card)
192.168.2.103 is a Calmotion LANCNC IP address (set in LANCNC.INI on the SD card)
- 16 2008-2009 Calmotion LLC, All rights reserved
The following is an example of what a network router LAN configuration page should
look like. You typically access the LAN settings via a web browser and type in the
routers IP address, in this example it is 192.168.2.1. This is a typical IP address of
routers.
A
B
C
Figure 9
A
This is the IP address of the router. If you type in 192.168.2.1 into a web browser, the
displayed router settings shown above should be displayed. The first three numbers will
need to be the same on the connected Calmotion LANCNC devices. The last number is
essentially the device number. The router is 1, the computers will be provided a number
from 2 to 100, and the Calmotion LANCNC will need to have a number from 101 to 254.
B
This is the subnet mask. This should never be changed.
C
Basically, these settings will provide 99 IP addresses to the DHCP, so that 99 computers
can automatically get an IP address from the router’s DHCP. It also frees up IP addresses
from 101 to 254 to static IP address devices, i.e. Calmotion LANCNC.

Example 3, Wireless Network connection to the LANCNC-FAD using a router and a
Wireless Bridge
The diagram below shows a Wireless Network connection to the LANCNC-FAD using a
router and a Wireless Bridge. It is suggested to use the router settings shown in the
previous section. This configuration will use the wireless router with wireless bridging
turned on to connect to another wireless router set up as an access point.

Use the following step-by-step procedure to setup the router and then the access point.
These settings are based on using a Belkin Wireless G router and access point:
Router Configuration
1. Open a Web Browser
2. In the address bar, type http://192.168.2.1
3. Click on Wireless Bridge in the left hand column under Wireless
4. Enter your password if any and click Submit
5. Check the box that says Enable Wireless Bridging, click Apply Changes.
6. Click Home, note the WLAN MAC address under LAN settings
Access Point Configuration.
1. Open a Web Browser
2. In the address bar type http://192.168.2.254
3. Click on Wireless Bridge in the left hand column under Wireless
4. Enter your password if any and click Submit
5. Check the box that says, Enable Wireless Bridging
6. Check the box that says, Enable ONLY specific Access Points to connect and
enter the WLAN MAC address from the router, click Apply Changes.
Note: The channel must be identical on both the router and the access point.
It is important that the router and access point use the same Channel, SSID, and security
settings. The access point will become another device on the routers network. When
both devices are using the same wireless communication parameters, they will be able to
communicate with each other.
Changing the IP address on the LANCNC-FAD device
The LANCNC-FAD defaults to IP address 192.168.2.111. If a different IP address is
desired, use a PC to create a text file on SD card with the file name LANCNC.INI in the
root directory. This file must be text only and have carriage returns at end of each line.
In order to change the IP address of the LANCNC to 101, the contents of the
LANCNC.INI file should contain the following:
CNC=57600
BYE=ON
IP address=192.168.2.101
IP mask=255.255.255.0
IP gateway=0.0.0.0
IP dns=0.0.0.0
Remember the last number on the IP address will be that Fadal’s “number.” To access
the files on that Fadal LANCNC file server, type in “ftp:192.168.2.101” in a web browser
to view the directory contents stored on the machines 1GB SD card.
- 19 2008-2009 Calmotion LLC, All rights reserved
Changing the baud rate on the LANCNC-FAD device
The LANCNC-FAD defaults to 38,400 baud. If a different baud rate is desired, verify
that the CNC can support the new baud rate to ensure that the CNC and the LANCNCFAD can communicate. To change the LANCNC-FAD device baud rate, an INI file must
be changed that resides on the LANCNC-FAD. Use a PC to create a text file on a SD
card with the file name LANCNC.INI in the root directory. This file must be text only
and have carriage returns at end of each line. To change the baud rate on the LANCNCFAD device to 9600 baud, type CNC=9600 in the first line of the LANCNC.INI file. The
LANCNC.INI file must be text only. The current version of LANCNC-FAD has been
tested at 9,600, 38,400, 57,600 and 115,200 baud.
Example how to change the LANCNC-FAD ftp address to 192.1678.2.113 and the baud
rate to 57600:
CNC=57600
BYE=ON
IP address=192.168.2.113
IP mask=255.255.255.0
IP gateway=0.0.0.0
IP dns=0.0.0.0
To complete the baud rate change, cycle power on the LANCNC-FAD. Enter the correct
baud rate on the CNC with the corresponding CD,8 CD,10 or CD,11.
Using the BYE= parameter
The BYE=OFF is for older CNC's that clear the screen after receiving the BYE
command. The BYE command is important because it closes the serial port and allows
the keyboard of the Control to start functioning again. If the BYE is not sent, press the
MANUAL key or the ENTER key to regain keyboard control. Set the BYE=OFF in the
INI file only if the control version clears the screen after a BYE command. Otherwise
keep it at the default of BYE=ON.
Trouble Shooting Guide
Problem: There is no response from the LANCNC-FAD device.
1. Verify the +7 to +30 VDC power supply is plugged into the device.
2. With power applied, at least one LED should be lit on the device indicating
power.
3. The straight through DB25 cable provided should be connected directly into the
machine. Do not use a null modem cable between the LANCNC-FAD device and
the machine.
4. Verify that the machine version supports the baud rate being used. CD,10 is for
38,400 baud machines. CD,8 is for 9600 baud machines. To verify the machine’s
- 20 2008-2009 Calmotion LLC, All rights reserved
capability, use the MU command at the ENTER NEXT COMMAND prompt and
go to page for Change Device.
5. Verify the LANCNC-FAD device matches the baud rate expected. The
LANCNC.INI file sets the baud rate on the device. Otherwise, 38,400 is the
default.
6. The LANCNC-FAD command set requires a plus to be used instead of the enter
key. After entering a command, end the command with a plus and do not press the
enter key or return key.
7. The CD,10 and CD,8 commands are CNC commands, not “plus” commands for
the LANCNC-FAD device. Press the enter key after the CD commands, do not
press a plus key at the end of the commands.
Problem: The CNC gives an error that the command is not recognized.
1. The LANCNC-FAD command set requires a plus to be used instead of the enter
key. After entering a command, end the command with a plus and do not press the
enter key or return key.
2. The CD,10 and CD,8 commands are commands for the CNC and not the
LANCNC-FAD. Press the enter key after the CD commands. Do not press a plus
key at the end of CD commands.
Problem: Program stops for no apparent reason when using DNC mode.
1. Use the DNCX X-modem feature if available on the Fadal.
2. Certain Fadal versions require comment block lines to have an N word on the
comment line. If they do not have the N word, the CNC will give an error. Delete
the comments or add N words to the comment lines. The same comment line can
be used if desired. The LANCNC dynamically adds an N1 before a comment
character. The comment character must be the first character in the line.
Problem: Part of the file is missing.
1. When using a PC, always use the “Safely remove hardware” icon before
removing the SD card from a computer.
2. On the LANCNC-FAD device, wait for the file to be completely saved after
