1 Overview
1.1 General
This manual describes the features and options of theWayWORD RV-DT-8R Mobile
Data Terminal (MDT). It also includes a section describing how the MDT’s features are
utilized within Raveon’s RavTrack PC GPS tracking and messaging application.

2 WayWORD Mobile Data Terminal
The WayWORD is optimized for GPS tracking and two-way data communications with
vehicle operators.
With 8 pre-defined status buttons, operators can quickly relay their status to a control
center. Users may add custom captions on the label area on the bracket below the status
buttons.
.
In summary, the WayWORD has these features:
192 X 64 pixel graphics LCD capable of 4 lines of 24 characters each.
8 buttons to automatically report pre-set statuses.
2 more buttons to allow data entry of digits 0-9 for two-digit event codes.
The LCD will display any text message sent to the radio modem it is connected to.
A simple code entry mode for the user to enter a two-digit event code. The code is
sent over the air, and can be displayed in RavTrack PC.
Mount bracket for connecting a RAM mount with 1” ball.
RFID reader option. If the RFID reader option is ordered with the MDT, it can read
an RFID key fob. If the operator holds an RFID tag near the RFID side of the
MDT, it will read the RFID tag number and transmit the number over the air.

3 Operating the WayWORD
3.1 Receiving Text Messages
When a new text message is received, the blue “NEW” led above the message window
will illuminate. The operator may press the or Xbutton to respond to the message. If
one of these two buttons is pressed the NEW led will turn off and the or X response
message is sent back to the radio modem that sent the text message. The WayWORD
will support displaying messages up to 96 characters.
3.2 Sending One-Button Status Messages
Pressing one of the 8 status buttons will toggle the state of the particular status.
If the state is not active and the button pressed, the state is set to active, and the green
led above the status button will illuminate. If the state was active, then pressing the
button will deactivate it and the green LED above the button will turn off.
When the radio modem that is connected to the WayWORD transits its GPS position
and status, the status of the 8 status buttons is transmtited every time.
3.3 Sending Two-Digit Event Codes
Pressing and holding any one of the numeric buttons(0 –9) for more than one second will
put the MDT into the two-digit event entry mode. The LCD will display the message
“Event Code: X”, where X is the first digit used for the event code and the corresponding
LED will flash, if applicable. The operator can then enter another digit (0-9) multiple times
until the intended code is entered, then press the check button to send it. Once sent,
the code is sent out the serial port to the radio modem.
3.4 Entering the UI Menu
By pressing buttons 1 and 2 simultaneously, it is possible to enter the User Interface
menu. From here, it is possible to change the LCD contrast, backlight, and flash timer

values in the LCD settings screen, check the current registered RFID tag, vehicle run time
and load count in the driver stats screen, and the model number, manufacturer and
current software version under the device info screen. Navigating through these menus
can be done by scrolling with the 0 and 9 buttons, and moving forward or backward with
the or Xbuttons.
3.5 Backlight Level
Pressing the light bulb button will result in the backlight dimming, then turning off, then
turning back on to full brightness.
3.6
Button
This button is responsible for confirming any prompts that come up on screen, and
navigating forward through the user interface menu. Inside of the UI menu, it may also be
used to choose the selected option.
3.7 X Button
This button is responsible for canceling out of every text prompt the MDT displays. In the
UI menu, it also functions to allow the user to move back a screen at a time until they exit
the menu.
3.8 Function Button
This button is implemented for future use in the event that additional features are added,
or existing features changed. Currently, this button does nothing.
3.9 Operator ID
To identify the operator of the WayWORD or the vehicle it is in, the WayWORD has a
Radio Frequency ID (RFID) tag reader that can read common RFID tags and key FOBs.
When the operator holds the RFID key fob near the RFID reader, the text display on the
MDT will display “YOUR ID: xxxxxxxxx” where xxxxxxxxx is the ID code of the RFID tag
read.
Upon reading a valid tag, the WayWORD will send the RFID code over the air. The
WayWORD will not store the RFID read upon power cycle, but the current operator will
be shown correctly in RavTrack.
4 System Setup and Configuration
4.1 GPS Tracking Systems
The reporting interval is programmed into the radio modem. Refer to the technical
manual of the radio modem to learn how to configure it for GPS status and position
reports.

Raveon Technologies Corp.
Company Confidential, 04/2013
4.2 Messaging Only Systems without GPS tracking
The WayWORD can be used in systems that do not utilize GPS tracking. Raveon’s
data radio modems will work well with this type of system. All MDT features work the
same as they do when used with or without GPS tracking.
5 Text Messaging Protocol
Text messages are sent to the WayWORD over-the-air from base stations or even
other WayWORDs. The WayWORD itself is a serial communication device,
compatible with Raveon data radio modems, but the WayWORD may also be used with
other modems or communication systems.
Each Raveon radio has a unique ID in it, so text messages can be sent to specific IDs or
to the preset group-ID for multi-cast messaging.
The WayWORD and the RavTrack PC application handle all of the technical aspects of
text messaging. Text protocol information is included here for users who want to write
their own text messaging application.

5.1.3 Parameters
To send information over the serial communications link to/from the WayWORD,
Raveon utilizes the Group Separator character to enable binary data and various
parameters to be communicated. Parameters start with the Group Separator (ASCII 29
or Hex 0x1D), followed by one ASCII character designating the parameter type, and then
the parameter. The end of parameter is the last byte, or a GS indicating another group is
coming. Parameter Codes

should be a ASCII 30/0x1E RS record separator character.
For example to send the text Hello World followed by flashing the text screen for two
seconds, the ASCII sequence of characters would be:
H e l l o <SP> W o r l d <GS> F 2 <RS>

11
Raveon Technologies Corp.
Company Confidential, 04/2013
5.1.4 End of Message
The <RS> character is interpreted as the end of the message. If a message is coming
into the MDT, and it pauses for more than 20mS, then the WayWORD will assume the
message has ended.
5.2 Status Button Messaging
If using a modem with WMX mode enabled, WMX will use a control byte (0x44) to
transmit status to the radio. The command SETBITS will be used to specify the bit pattern
of all the status bits in the form of:
SETBITS XXXX[cr]
Where:
XXXX is the bit representation of all status bits.
[cr] is a character return
BITS:
0-3: External Digital Input Bits From MDT
4-7: Digital Output Bits From MDT
8-15: Status Bits 1-8 of MDT Inputs and Outputs
5.3 Text message Format
All text entering the WayWORD will be displayed as a message on the text display of
the MDT. To put the phrase Hello World onto the display, simply send the phrase
Hello World to the display using a radio modem or its RS232 serial port.
However, the WayWORD has many additional advance features that you may utilize if
you properly format the text to put on the display.

6.4 Connector Wiring
For those interested in how the I/O connector is wired inside the WayWORD to the
microcontroller of the WayWORD, below is a schematic diagram of the connections.
6.5 RS232 Serial Interface
An RS232 serial port on the MDT connects to a radio modem. Typically, that radio
modem will communicate with a base station. All WayWORD units will ship with a
3m(10ft) male-to-female straight cable to ensure quick and easy setup between a radio
and the WayWORD.
6.5.1 RS-232/EIA232 Serial I/O Connector
The RS-232 9-pin serial I/O connector is a male 9-pin D-subminiature connector having
the following pins configuration. It is pinned out so that it may be plugged directly into a
radio modem (such as the M7).

6.6 Command Mode
The WayWord may be put into a “Command Mode”, by entering a sequence of three plus
characters (+++). To keep the WayWord from unintentionally entering the Command
Mode because of the +++ pattern occurring in a stream of data entering the modem, there
must be a pause in the data stream before the +++ as well as a pause after the +++ is
sent. If either pause is missing, the modem will not enter the command mode.
Using serial communications software such as HyperTerminal, send the 3-character
command sequence “+++”.
When the WayWord first enters the Command Mode, it sends the phrase “RV-DT-8R” out
its serial port, and then an “OK” sequence. The “OK” sequence is a sequence of 4
characters:
“O”, “K”, <CR>, and <LF> characters (<CR> = ASCII 0D, <LF> = ASCII 0A)
Note that the internal power-management function may turn the product off to save
power. When the radio powers on, it will send an “OK”.
To ensure the device is on, and able to be put into the Command Mode, you may turn the
unit off, and then back on.
6.7 Setting a Parameter
To set a parameter in the WayWord, enter the Command Mode as described above.
Then enter the proper command, a space, the parameter, and then a carriage return
(enter). For Example, to set the destination address of the WayWord to 1234, enter the
following command:
ATDT 1234 <CR>.
Once a Parameter is changed, it will be permanently saved and the modem will begin
using the new parameter.
Reading a Parameter
To read the value of a particular setting, issue the command with no parameter. The
modem will return the value followed by an “OK”.
For example, if the user enters the command to read the WayWord’s destination address
and its address was 1234, the user would issue the following command:

16
Raveon Technologies Corp.
Company Confidential, 04/2013
ATDT<CR>
and the modem will respond with:
1234 <CR> <LF>
OK <CR> <LF>
To get on-line help with a command, enter the command and put a question mark in for
the parameter. For example, to see what the ATDT command is used for, type ATDT ?.
The modem will respond by listing a brief description of the command. To see a list of all
commands, type HELP.

7 Radio Modems
The WayWORD connects to a radio modem that is used to send and receive its data.
Raveon has a number of modems ideal for WayWORD data communications:
7.1 RV-M7 Series GPS Transponders
This transponder is available in either the UHF frequency band or VHF band. The M7-GX
has 4 connectors:
1) GPS antenna connector
2) RF I/O antenna connector
3) DC power in
4) Digital inputs (RS-232).
At a programmable interval, the M7 transmits a short, compressed, and encrypted

a. Configure the System Communication channel that is linked to the base
station radio modem to use WMX. The communication device to select in
the System Communications is a “WMX Radio Modem”.
b. For M7 base stations, select “WMX Radio Modem, (38.4k baud)”as the
Device. Any Device that uses WMX as the communication protocol should
work.
c. On the Program Properties > Mobile Data tab, make sure the computer that
is connected to the base station has the “This Computer is the Message
Server box checked.
d. On the Program Properties > Mobile Data tab, choose the channel to use for
outbound messages or check the box “Use Last” to send the message on
the channel the data terminal or GPS transponder was last received on.
8.4 Configure the IO Profile.
New in RavTrack PC version 6.0 is the concept of a “Profile”. A profile describes the
configuration and use of the IO bits, status bits, and event codes. Any number of
Profiles may be created, and every tracked object must be assigned to some profile.
A “Default” profile will be used by all new tracked objects that are added to the system
until they are assigned to a different profile. You may create your own profiles or edit
the default profile to suit the system needs.
To edit and configure Profiles, go to Tools > Configure Status and Event Codes > and then
select Status bits, Input Bits or Event Codes. This will bring up the edit window to edit the
selected profile information.
Click Add Profile to create a new profile.

In any of the description columns, click on any description to edit it. Hit <enter> key
when you are done editing the field. When done editing, select File>Save to save your
edits.
The Profiles are stored in the SQL server’s RavTrack database, so all other computers
running RavTrack PC will use the same profile settings. If you edit or create a profile,
restart RavTrack PC on any other RavTrack PC computers so that they use the new
Profile settings.
Set the “Active State” to either 0 or 1 depending on which state you want to consider as
active. When a particular bit is “Active” it will display with the arrow symbol in the
status window, as shown below where the status code 1 was active.
