1INTRODUCTION
Summary
- This device (software and hardware) adds a Wi-Fi interface to any Yamato products that use a VS-
4, VS-6 operating in VS-4 mode, or CR5A Planar controller board. Examples include all DKN series
ovens and FO series muffle ovens. It enables operators and managers to remotely interact with an
oven located anywhere on a provisioned local network (or the internet).
- Oven remote operations/monitoring/logging can be done securely by using a PC or Smart phone
connected to same network as the Bridge, either with a web browser accessing the built in pages on
the WBV bridge or by customizing your own web pages and accessing the bridge using its provided
API.
- All functionality present on current VS-4 RS485 communication interface (OP-19) is also available
through the Wi-Fi bridge but in a more user-friendly way: The low level RS-485 serial
communication protocol is encapsulated into Web Socket packets over TCP/IP, which is supported
by all Internet web browsers and other IoT platforms like IBM's Node-Red. No need to calculate
checksums, delay times, etc. The bridge does all that.
- In addition, extra information can be stored in the Wi-Fi bridge and retrieved remotely using any
web browser remotely. Ex: Temperature logs for any past date.
- The software API (Application Programming Interface) adds convenient functions like Program
Upload/download from a PC, in-browser Program editing /save back. Real Time Status monitoring,
data logging, etc. Because it is built on top of HTTP/Web socket server standards, adding even more
functions to the final application is easy (for an HTML / JavaScript programmer, that is).
- The Wi-Fi Bridge and API should also work on CR5A equipped ovens “as-is” and they can be ported
to VS-5 and other Yamato controllers running Modbus with minimum effort, saving customer
application development and deployment time as the remote control and monitoring User Interface
would be the same for all ovens.
- Thousands of Wi-Fi bridges (and ovens) can co-exist on the same network. Each one gets its own
‘network’ name automatically assigned by the Wi-Fi bridge device based on its Network MAC
address, which is unique by definitions. Ex: A Wi-Fi bridge with MAC address A6:55:F3:1A:2B:3C will
assign itself the name "WBV-2B3C". Traditionally, all devices with an Ethernet interface (Wi-Fi or
wired) should have a label on the unit indicating its MAC address. The WBV4 Wi-Fi bridge is no
different. A locator function makes it easy to locate one particular Oven in a sea of ovens: an user
can issue a “ID ON” command to a Wi-Fi bridge and it starts blinking its bright Yellow LED, making it
easier to spot.

2INSTALLING THE WI-FI BRIDGE ON A DKN-XXX OVEN
1. VS-4 Wi-Fi Bridge modules:
The Wi-Fi Bridge is implemented as two interconnected modules: One module is installed inside the oven, next
to the Planar board, and another module is installed outside the oven, next to the Option Terminal Block
located on the right side of the oven. To install the module inside the oven, first make sure AC power cable is
disconnected from main Power and Main circuit breaker is set to Off.
2.1.1 Power Supply and RS485 to TTL converter module installation
The Power supply/RS485 module has two harnesses and one USB type A female connector: The AC power
harness is terminated two female receptacles (blue or Pink color). Those receptacle should be inserted on
vacant positions of Terminal Blocks TM1, labeled “1” and “2”, The two wire communication harness should be
connected to VS-4 CN3, pins 3 and 4. If you received a unit with a shielded cable on a 4 pin header block, plug
this connector on VS4 connector CN3 so that the coaxial cable “sits” above CN-3 pins 3 and 4, not pins 1 and 2.
If your device has a two wire connector, the Black wire should be aligned to pin 4 of CN3, while the lighter color
wire (white or yellow) should be on pin 3. The supplied USB “A” to Micro USB 6’ cable should be connected to
the power Supply module on the “A” side. The Micro USB end of the cable should be routed to the outside of
the oven enclosure and connected to the Control and RF module. Remove the extra metal cover plate located
next to the Option Terminal block and use that opening to string the cable out. See figure 1.

2.1.2 Control and RF module installation
The control and RF module contains a microcontroller and a 2.4 GHz b/g/n Wi-Fi radio. It needs to be placed
outside of the oven enclosure to increase Wi-Fi communications range (antennas don’t work well inside
shielded metal boxes.) Connect this module to the cable coming from the Power supply module and attach it
to the side or top of the oven.
This module has a magnetic base that should be used to keep the module attached to the oven’s metal
chassis. Best performance can be achieved by placing the Wi-Fi module on top, or on the right side face near
the top and close to the oven door, with the antenna pointed up. Avoid spots that get unusually hot (ex:
don’t place the unit near the exhaust ports).

3CONNECTING THE BRIDGE TO A WI-FI NETWORK
2. Choosing a Wi-Fi access point.
Although the Wi-Fi Bridge has a powerful radio, it conforms to international standards for EMI emissions,
which limit the maximum radio power that can be used. That being said, the maximum recommended distance
between the Wi-Fi Bridge and the Wi-Fi access point it will connect to is 50 meters on an unobstructed area.
Walls and other large metal barriers will reduce the Wi-Fi range. Ideally, the Wi-Fi Bridge should be placed on
top of the oven.
IMPORTANT: In order to use the Temperature Logging function and to evaluate its License status,
the Wi-Fi Bridge must have access to a Network Time Server (ntp) on the internet. If the device is
not allowed to connect to “ntp://us.pool.ntp.org” or “ntp://ntp1.aliyun.com”(Chinese builds)
another time server on the local network must be provided by the DHCP server.
3. Connecting to a Wi-Fi Access Point for the first time.
To configure the Wi-Fi Bridge to connect to an Access point, the following procedure should be used:
If there is no Access Point name pre-programmed on the Wi-Fi Bridge, or if it cannot connect to a previously
configured Access Point, the bridge enters Wi-Fi Setup mode: It starts its own Access point and activates its
bright Red LED light. The installer should use a PC or cell phone and connect it to the Wi-Fi bridge’s Access
Point, with SSID “WBV-nnnn”. The value of ‘nnnn’ can be found on a sticker placed on the Wi-Fi Bridge itself.
After connecting to the Bridge’s Access Point, open a web-browser and navigate to http://192.168.4.1. A
configuration web page will be displayed. Click “Configure Wi-Fi” to see a list of detected Wi-Fi networks.
Select the correct one for your installation and enter the Wi-Fi password. Click “Save”. The Bridge turns its
Access point OFF, reboots and try to connect to the new Access point. If connection fails, the bridge resets and
re-enable its Internal AP. If connection is successful, the Bridge will light itself Yellow and then Green.

4ACCESSING THE WI-FI BRIDGE
4.1 Testing Wi-Fi connectivity
On a computer or smart-phone connected to the same local network as the Wi-Fi Bridge, navigate to
Http://WBV-nnnn/ or http://WBV-nnnn.local/ .NOTE: Some Wi-Fi access points and Routers do not allow
clients to broadcast its mDNS or NetBIOS names. If you can’t find your Wi-Fi bridge after it is showing a Green
color LED, ask your IT person to find out the IP address of the WBV device and use it to access the bridge (ex:
http://123.123.123.123/ and also ask for the WBV-nnnn be added to the local DNS server. Once the Bridge
gets an IP address it will always try to use that same IP, even after Power off.
Before the Main Menu screen is displayed, an authentication pop-up appears. It asks for Username and
Password information. For now, the Use name is fixed at “WBVuser” and password is “Yamato”. After
entering these credentials, the Main Menu screen should be displayed. There, you can easily go to the local
File Editor tool, see temperature log charts, update the firmware or navigate to the Remote Operations page.
Just click one of the available buttons. Use the command line field to enter pre-defined commands to the
Bridge and see results in the window immediately below it. They are case insensitive (typing “help” is same as
typing “HELP”, “T” = “t”, etc. The “help” command will display the available commands for the firmware
version you have on that device.

4.2 Wi-Fi Bridge’s Home page (Main Menu)
The Home Page of a WBV web interface consists of three areas: Sub-menu buttons, a Command Line frame
and a Oven Status frame. A WBV model A displays a chart with the last 240 temperature samples from that
day’s Temperature Log, if logging is enabled. WBV models B and C home page always display the current
temperature and oven status on a large window next to the Command Line frame. Typing the letter ‘T’ or ‘t’
on the command line and pressing Enter will also returns the current temperature on the response box. (NOTE
commands are not case sensitive). The Bridge queries the Oven, gets a reply, formats it and sends it to the web
browser (in Celsius). If, after a few seconds, the Oven does not reply to the bridge, a communication error has
occurred. The Wi-Fi Bridge will start blinking the color Magenta until the communication with oven is restored.
4.2.1 Differences between WBV4 models A, B and C.
This user manual includes information for features available in model A. However, models B and C support
only a subset of those features. Model C units do not support functions related to Data Logging or Remote
operations. Model B units do not support functions related to Data Logging.
When any WBV4 unit is turned on for the first time, it assumes the identity of a WBV4 model A for 30 days.
After that, the unit will assume the identity of Model C unless the user activates it with a License For model A
or B. The customer should have received a License file corresponding to the purchased model by e-mail. If
that has not happened or customer wishes to upgrade the unit to a model B or A, contact Yamato-USA. To
activate the License file on a WBV4 unit use the File Editor utility (from Home page), click ‘Chose File’ and
Upload the license file. Once user clicks Browser’s ‘back’ button, a message will be displayed on the
Command Line frame indicating the acceptance or failure of the License file. If accepted, the unit will reset
and it should assume the identity matching that of the license.
4.3 Commands available on the Command Line interface
Most commands listed below have two versions: the one listed and another one followed by a J. Ex: 12 and
12J. The J version returns the information requested as a JASON string. It is useful for creating you own
custom scripts.
4.3.1 Getting Oven status: command ‘12’.
The Bridge’s home page display’s the oven status on top of the temperature (all models). Remote Operators
can also type command ‘12’ on the Command line frame and the status will be displayed on the response box.
Alternatively, Model A and B bridges also display status information on the ‘Remote Operations’ page. If oven
is idle, no further status is displayed. If oven is running a Program or Fixed temperature, more details are
shown.
keypad:.... Locked
Run/Idle:........ Idle
Op. mode:.... Fixed temp
Output Monitor: 10000
Target Temp:..40

4.3.2 The “Nickname” command
The “Nickname” command allows the user to assign a more familiar name to an Oven, which is displayed on
several screens. Once set, the oven’s network name (mDNS and NetBios) changes to the set name. After that,
the Wi-Fi Bridge is accessed at http://nickname.local/ (Apple Mac and IO/S) and http://nickname/ (Windows
PC). Command Usage:
“NN” : displays current Friendly name;
“NN new_name” : sets Friendly name to new_name and reboots bridge
“NN .” : deletes the Nickname, if any, and resets the bridge name to its original name.
After the command is executed, the Bridge will re-start.
4.3.3 Restart: Command ‘00’.
This command will cause a bride to re-start. It may take up to 20 seconds for the bridge to connect to the
programmed Wi-Fi Access Point and another 30 seconds for it to get the current GMT time from an NTP Time
Server. Operations will not resume unless the bridge can acquire the GMT time from the network. To access
the home page again, press your browser’s refresh button.
4.3.4 Wi-Fi Reset command: ‘13’
The ‘13’ command will erase the Bridge’s current Wi-Fi settings and cause a re-start. Upon re-booting, the
Bridge will start its internal Acess point and the user will need to re-configure the local Wi-Fi AP name and
password, just like on the initial installation procedure.
4.3.5 Bridge information command: ‘14’
Enter 14 at the command line to see information on your Wi-Fi Bridge. This may be useful on a technical
support call. The same information is shown on the Bridge’s home page when it is loaded or refreshed
(response panel).
4.3.6 Bridge Locate commands: ‘ID on’, ‘ID off’
The ‘ID on’ command will cause the bridge to glow itself Amber color (blinking) until the command ‘ID off’ is
issued. Used when remote operator needs to locate one particular oven amongst many.
4.3.7 Read VS-4 Register command: ‘RABC’ (models A and B)
Type ‘R’ followed by the 3 letter VS-4 register name to read the value programmed in that register. Register
name must be typed in CAPS. EX: to read register PV1, type ‘RPV1’ on the command box. Bridge returns the
register name followed by the value in it.
4.3.8 Write VS-4 register: command ‘WABCnnnnn’ (models A and B)
Enter ‘W’ followed by the 3 letter register name and a 5 digit numeric value on the command box. . Register
name must be typed in CAPS Ex: writing the Operation start/stop register RUN with value 00000. Oven
replies OK or Error.

WI-FI Network Bridge um-R1.3

4.3.9 Saving an Oven program into a file on the Wi-Fi Bridge command ‘PnS’
Enter ‘P’ followed by Program number (1, 2 or 3) and letter ‘S. A file named ‘Program’n’.txt’’ will be created
or updated on the Wi-Fi Bridge. It is a simple text file that can be edited by the built-in File Editor or
downloaded to a computer on same network. Likewise, there are commands to Upload a program file to the
bridge and then load them back into the oven for use.
4.3.10 Loading a program file into Oven: Command ‘PnL’
Enter ‘P’ followed by the program number you wish to load into oven and the letter ‘L’. If exists, the program
file will be loaded into the oven.
4.3.11 Starting Fixed Temperature operation remotely. Command ‘SFT ttt’ (models A and B)
On the command line, enter “SFT nnn” where nnn is the three digit target Temperature. The oven will change
state from Stop to Run and the heating element will be turned on. The oven will heat up until the Target
temperature is reached. It will then keep the chamber at that set temperature until the “Stop” command is
issued. This function is also available on the Remote Operations page (graphical interface).
4.3.12 Starting a Program remotely. Command ‘RUN np’ (models A and B)
If this option is enabled, you can start one of the three programs stored into the Wi-Fi Bridge by entering the
command “RUN np”, where ‘n’ is the program number and ‘p’ is desired pattern within that program.
Program execution will stop once the last step has finished or the Stop command is issued. . This function is
also available on the Remote Operations page (graphical interface)
Because this involves loading the oven with a complete program, it may take up to 30 seconds for the Bridge
to acknowledge the command.

5LOGGING OVEN TEMPERATURE (DATA LOGGER FUNCTION)
WBV-4A Wi-Fi Bridge model supports data logging functionality. It can be set to periodically save a record
containing a precise date/time (derived from GMT time) and the corresponding oven temperature. By default,
this data is appended to daily log files, which are created at 00:00 AM and closed at 11:59 PM. These daily log
files are kept in the Bridge’s Flash memory until the Operator downloads/deletes them using the File Editor
utility. The file name correspond to the file creation date. EX: file 20200325.txt contains all data points collected
on March 25th, 2020.
To setup the data logger configuration, use the ‘Log’ command, on the Command line window as follows.
5.1 “Log [nn]” command
The ‘Log’ command can be issued without parameters, in which case it returns the Log operation state and the
current log interval. When used with the ‘nn’ parameter, it sets the number of minutes between data point
captures. If ‘nn’is set to ‘00’, logging will not occur (disabled).
NOTE: Whenever the user changes the Log interval or enables/disables Logging, the Wi-Fi Bridge will re-start.
FIGURE 9-LOG STATUS QUERY FIGURE 10 –SETTING LOG FUNCTION
On the left figure above, the ‘Log’ command is issued without parameters and the Bridge returns the current
setting. The factory default for Model A is Logging Enable with Sample interval = 1 minute.
The figure on the right shows user setting Log sample interval to 10 minutes. After Enter is pressed, the new
value is saved and the Bridge resets itself. The user needs to manually refresh the page. If Log Sample
Interval is set to ‘00’, No logging will occur (Log Disabled).

WI-FI Network Bridge um-R1.3
14
5.2 Viewing/Retrieving the log files:
The log files are not deleted by default. They will remain in the Bridge’s Flash memory until the operator
deletes them using the built-in file editor. When the Flash memory fills up, data logging will stop until older
files are downloaded/deleted. The daily log file size is dependent of data sample interval and the number of
minutes the oven is running. Each data sample saved is 16 bytes long.
Ex 1: Logging temperature every minute, 24h/day will consume 23Kilo bytes per day. At this rate, the Bridge
can save 60 days of data in its Flash memory. (Worst case scenario). Operator needs to download/delete older
files at least every 60 days.
Ex 2: The sample rate is set to 4 minutes and the oven only operates 8 hours per day (by default, capture only
occurs if the oven is ON and temperature inside the chamber is >= 25 Celsius). In this case, the bridge can keep
about 2 years of data in its Flash memory before it fills up.
By default, the Home page of WBV4 model A displays Today’s temperature chart as taken from the log file
corresponding to Today’s date. The chart is dynamically updated every minute to include a new data point
even if Log function is disabled. On that web frame, the user can chose another date to display its Temperature
chart (if logging was enabled for that date and the file was not deleted…) or chose how many point to display
(from the file tail). A larger chart view can be reached by clicking Temperature Logs button. To view/download
or delete Log files, use the File Editor tool (see next chapter and refer to figure below).

6THE FILE EDITOR:
One important function of the Wi-Fi Bridge is its powerful file Editor. It can be accessed by clicking the “File
Editor” button present on some of the Bridge’s web pages. The file editor utility is an open source javascript
editor that can run on any modern browser. However, due to its size, it is not located in the Wi-Fi Bridge itself.
Instead, the browser fetches it from a public repository on the internet when it is invoked. Therefore, to use
this function, the client PC or device that is accessing the Wi-Fi Bridge has to have internet access. Only text
files are available for viewing/editing or downloading. Selecting a files from the file list on the leftside of the
window causes the editor to load the file on the screen. In this example, “Program2.txt” was selected. This file
is generated with command “P2S” issued on Bridge’s main web page.
FIGURE 12:JAVASCRIPT EDITOR PAGE
6.1 Standard file names and descriptions:
The Wi-Fi bridge has a simple built in File System that stores files necessary for the bridge configuration, its
Web interface and other programs for communicating with an oven. For security reasons, only .txt files are
displayed.
readme.txt: almost same as the Help command, but may contain revision information and other tips
YYYYMMDD.txt: Log files are saved with this file name convention: YYY is the Year, MM is the month, DD is
the day). If logging is enabled, the current file is closed at midnight and a new file is created to continue
logging operations.
Programn.txt: Program files contain program patterns. Generated by ‘PnS’ commands or upload from PC
using this file editor page. These files are stored on the Wi-Fi bridge and not on VS-4 controller. If the file has
been modified, the operator must load that file into VS-4 controller before it can be used. Use API command
“PnL” to upload Program file ‘n’ into VS-4. Or use command “RUN np”, which does that automatically.

6.2 Working with files
Left clicking a file name with the mouse will load the file into the editor right side of the screen and it can be
edited by simply typing over the file data and saving it by pressing ‘Ctrl’ + ‘S’.
Right clicking on a file name will display a pull down menu with a choice of Edit, Download or Delete the file.
The download file option will cause the browser to download the file into the PC or phone that started that
operation. On this example, Program3 file is being edited. NOTE: Deleting a file cannot be undone.
FIGURE 13:WORKING WITH FILES
NOTE: Another way to download files from the Bridge to a computer without using the editor utility is to
point your browser directly to the file you want. Ex: to download file Program2.txt, just navigate to page
Http://wbv-nnnn.local/Program2.txt . The file will be displayed on the browser window and you can save it to
the computer by using mouse Right click and selecting “Save as…” option.

7UPDATING THE FIRMWARE
Should it become necessary to update the Firmware of the Wi-Fi Bridge, a binary file (.bin) will be made
available to the customer. It can be programmed into the Bridge by the Firmware Update function, accessed by
clicking the button of same name at the Wi-Fi Bridge main menu page. The procedure should happen as follows:
a) Make sure you can access the new binary file. It should be between 350KB and 500KB in size.
b) Open a Web browser session on the Bridge you want to update.
c) Click Firmware update button on Wi-Fi Bridge main menu.
d) Select the new (.bin) file by clicking Chose File button (An OS pop-up window help you with that.)
e) Back to the Update firmware web form, the Update button.
f) You can track the file upload progress on the bottom of the browser window
g) Once the firmware file has been uploaded, the Bridge will validate its content (MD5 hash) and proceed to
self-update. This phase should take approximately 30 seconds and the Web Browser will disconnect from
the Bridge if the update is successful.
h) Reconnect your Web Browser session to the Bridge’s main page as you would for a new session.
