NOMAD™ - NRT202
O
PERATINGINSTRUCTIONS
The NRT302 data terminal is a hand-held wireless keypad and display for
entry of numeric data. This terminal provides the primary data entrymethod
of the NOMAD system.
Data entry is guided by menus displayed on the graphic display.
The terminal is powered by rechargeable batteries with a built in charger
that draws DC power from a charging adapter. In an emergency, the
rechargeable battery may be replaced by standard alakaline batteries
providing no attempt is made to charge the unit while fitted with the nonrechargeable battery.
The terminal does not have to be in radio range for data entry to take place.
All data entered is stored in the terminals own memory (the memory is
maintained even if the battery is discharged) and then sent to the NOMAD
system whenever there is a good communication link. To the operator this
is a seamless process. This is a key strength of the NOMAD system essential operation is guaranteed regardless of sporadic radio interference.

PERATINGINSTRUCTIONS
3. SETTING UP A TERMINAL FOR FIRST USE
Before a terminal can be used on the NOMAD network it must be assigned
a node number so that the system can distinguish it from other terminals in
the system. This will also clear the memory of the terminal and inform the
system that all relevant menus should be uploaded into the terminal.
3.1 ENTERING A NODE NUMBER
Every terminal on a given system must be uniquely identified by a node
number. Entering a node number on a terminal also initialises it for use on
the system by clearing the terminals memory and requesting a full update
from the system of all menus.
After inserting the batteries or removing the terminal from its charging
station a startup message is displayed.
PAGE 6 of 15
To set the node number, press the 3 and the 9 keys simultaneously while
this message is displayed. The prompt “Node ?” will be shown.
The node number is entered as 5 decimal digits: xyzzz
zzz = the node number.
y = the language.
x= the system number.
The node number itself can be in the range 1 to 231. It is these three digits
that identify the terminal on the system.
Page 7
NOMAD™ - NRT202
O
PERATINGINSTRUCTIONS
The language number can be in the range 0 to 3 and indicates which
language the menus should be. The default system language is 0.
Additional languages (up to three) can be defined in the system setup for
NOMAD and individual nodes then initialised to one of these. This way
employees of different languages may work on the system side by side.
Note that to change language the terminal has to re-initialised and its
memory cleared as above. If a language number is entered that hasn’t
been defined in the NOMAD system then the default language is used.
The system number can be in the range 0 to 3. The default system number
is 0. Different system numbers can be entered in the Radionet application
and a terminal will only communicate with a system on its own number.
This allows adjacent systems to work independently.
After entering the node number as above press the ‘ENT’ key. The terminal
will then initialise its memory after which the startup message will be
displayed again.
PAGE 7 of 15
3.2 CHANGING OPERATING MODES
The terminal can be set to be used by an individual or by a group. The
normal mode after initialisation is for individual use.
Multi-user mode is intended for the situation where a supervisor is entering
in data for several employees. It allows the operator number and time to be
set for each data entry.
The mode is changed in a similar fashion to setting the node above. During
the startup screen press the ‘4’ and the ‘CLR’ keys simultaneously. Each
time this is performed the mode will toggle between normal and multi-user.
4. THE LCD SCREEN
4.1 STARTUP MESSAGE
The start-up message indicates the firmware versions for the terminal along
with the system and node numbers.
Page 8
O
In the example above the firmware bootstrap is version 5.0.5, the main code
version is 5.7.4, the system number is 0 and the node number is 002.
The start-up screen shows for 5 seconds and is shown whenever the
terminal is removed from the charging station or the batteries are inserted.
4.2 STANDBY MODE
The default display for the terminal takes the general form below,
NOMAD™ - NRT202
PERATINGINSTRUCTIONS
PAGE 8 of 15
A typical display after removing a terminal from the charging station. It
shows the time, the node number and the percentage of memory used. It
also shows the operator number and name of the person registered to the
terminal along with the currently selected task for RFID use.
This shows that operator 1 has clocked on. There is one message (01%)
waiting to be sent to the system (the clock on message).
Page 9
NOMAD™ - NRT202
O
PERATINGINSTRUCTIONS
The message has been sent (00%) and confirmation that operator 1 is
recognised in the system is shown by displaying their name. If operator 1
had not been recognised then the following would be displayed.
PAGE 9 of 15
If the battery starts to get low the “Batt” symbol will alternate with the battery
voltage in the lower left corner. When the battery has insufficient power to
operate the terminal reliably the “Batt” symbol will be displayed
continuously.
4.3 PAGING FACILITY
There is a facility within the NOMAD system to send short text messages to
specific terminals. When such a message is received and the terminal is in
standby mode it will give a series of beeps and the standard display will be
replaced by the text message, which will flash on and off.
To cancel the message and return to normal standby mode press and hold
the 4 and 6 keys as if about to enter data. This will cancel the page
message. Press the ‘CLR’ key to return to standby mode.
4.4 FEEDBACK
If operator feedback is enabled on the NOMAD system a message is sent
to the operator after each task code (for which feedback has been defined)
has been received by the system. When the terminal receives the message
a double beep will be emitted.
Page 10
O
To view the feedback message press and hold the up arrow key while in
standby mode. Releasing the up arrow key will return the terminal to
standby mode.
4.5 MULTI-USER
If in multi-user mode the operator number/name will be replaced by “MUSER”
NOMAD™ - NRT202
PERATINGINSTRUCTIONS
PAGE 10 of 15
5. ENTERING DATA
The normal state of the terminal is standby - the keypad is locked against
accidental operation.
5.1 NORMAL MODE
To exit the standby mode press and hold the 4 and the 6 keys together. A
prompt inviting the user to “Enter Command” will be displayed.
Note that all or some of the prompts may have been redefined in the
NOMAD system depending on the language settings.
Key in the number of the task to be entered. As the digits are keyed in a
menu prompt will be displayed if the task code is one that has been
defined.
Alternatively, if the task code is not known press and hold up or down arrow
keys to scroll up and down through the available task codes.
Press the ‘ENT’ key when the desired task code is displayed. Further
prompts may be displayed requesting the user to in turn enter any additional
parameters required by the task code. For example, after pressing ‘ENT’ for
Page 11
O
“Clock In” the user is prompted for “Operator” and should enter their works
number.
The number of digits that the terminal will accept will vary depending on the
parameter and the setting made in the NOMAD system.
Note that the terminal will only accept codes other than “Clock In” (code 0) if
the user has clocked in. Once clocked in the prompt for code 0 will change
to “Clock Out”. After pressing enter to “Clock Out” the user will be prompted
to “Confirm”. This is done by pressing the ‘ENT’ key again.
5.2 MULTI-USER MODE
To exit the standby mode press and hold the 4 and the 6 keys together. A
prompt inviting the user to “Enter Operator” will be displayed.
Enter the operator number for the task to be entered and press ‘ENT’. A
prompt inviting the user to “Enter Time” will be displayed.
NOMAD™ - NRT202
PERATINGINSTRUCTIONS
PAGE 11 of 15
The current time will be display in the lower right corner of the screen. To
accept this press the ‘ENT’ key, else key in the required time and press the
‘ENT’ key.
The rest of the process is as per section 5.1 above.
6. RFID ENTRIES
All entries can also be made with the built in RFID reader. Pressing the
scan will activate the RFID reader for 10 seconds or until a valid tag is
found. The terminal should be placed with the rear of the casing adjacent to
the RFID tag/card to be read.
6.1 WARNING TONES
There are three possible results of reading an RFID tag and each produce a
different type of beep from the terminal.
The tag is read and accepted – single beep
The tag is read correctly but rejected (for example, an attempt to
enter a task before being clocked in) – three distinct beeps.
Page 12
O
The terminal was unable to read the tag – long waning tone with two
distinct pitches.
6.2 RFID TYPES
The standard terminal will only recognise MIFARE RFID tags or cards.
6.3 MAKING AN ENTRY
A typical sequence for operator 1 and task number 3, interrupted by task
100 might be as follows.
1. Scan “clock in 001” label (in the canteen/entrance area)
2. Scan “select task 003” label (in the canteen/entrance area)
3. Scan “row” label (in the glasshouse)
4. Scan “row” label (in the glasshouse)
5. Scan “enter task 100” (in the canteen/entrance area)
6. Scan “row” label (in the glasshouse)
NOMAD™ - NRT202
PERATINGINSTRUCTIONS
PAGE 12 of 15
In the above sequence, the first scan (clock in) results in an entry in the
terminal. The second scan (select task) does not produce an entry in the
terminal. The third and fourth scans produce entries for task 3 with the row
number scanned. The fifth scan (enter task) produces an entry in the
terminal.
The meaning of the task numbers depends on how the system has bee set
up, task 3 might be to de-leaf a row of fruit and task 100 might be a coffee
break.
Note that the selected task remains selected in the terminal even when a
directly entered task (such as coffee) is scanned. In this way the operator
can continue with their selected task by scanning the next row number.
6.4 KEYPAD ENTRIES
It is also possible to use a combination of keypad entries and RFID entries.
It might be desirable for the operator to use keypad entries for clocking
in/out and selecting tasks and only using the RFID labels for the rows for
instance.
Page 13
NOMAD™ - NRT202
O
PERATINGINSTRUCTIONS
Conversely, some customers might not appreciate the benefits of labelling
every row within a glasshouse yet want greater security over clocking in and
task selection. With this in mind a RFID only mode is available.
6.5 RFID ONLY MODE
In RFID only mode, it is still possible to enter a row via the keypad but all
other entries, including task selection, must be made via the keypad. RFID
only mode is indicated on the screen via “BC” in the top right corner.
To activate/deactivate the RFID only mode the ‘0’ and ‘2’ keys should be
held down while the start-up screen is shown (see section 2).
7. ERROR MESSAGES
PAGE 13 of 15
7.1 CLOCK NOT SET
If the internal clock has not acquired the current time from the NOMAD
system then an error message will be displayed “CLOCK NOT SET”. If this
message is displayed ensure that the terminal is within range of a link unit
to allow the terminal to acquire the time. Once the time is acquired the
internal clock of the terminal will maintain the time until power is lost.
7.2 FLAT BATTERY
If the rechargeable battery is at a level where safe data entry cannot be
guaranteed the terminal will prevent the operator from entering data and a
“Flat Battery” message will be displayed whenever data entryis attempted.
The terminal should be placed back in its charger and the battery allowed to
charge. Alternatively, the battery could be replaced with a spare fully
charged battery.
DATA WILL NOTBE LOST IF THE BATTERY FULLY DISCHARGES.
7.3 MEMORY FULL
If the memory has insufficient space to make another entry the “Memory
Full” message will be displayed. If this happens ensure that the terminal is
Page 14
O
in communication range of a link unit to allow the system to extract the data
and therefore free up memory. While this is happening the % meter in the
lower right corner of the display will be seen to decrement as each
message is sent.
8. CHARGING
There is no on/off switch on the terminal. It is intended that it is either in
use or on charge. No harm will be done to the battery if the terminal is left
on charge for indefinite periods.
To charge the terminal place it in the charging station so that it is sitting with
the display showing and ensure that the terminal is slid all the way down in
the charging station. After a second has elapsed the terminal will beep and
the message “CHG1” or “CHG3” will be displayed. These messages
indicate that the terminal is charging.
NOMAD™ - NRT202
PERATINGINSTRUCTIONS
PAGE 14 of 15
The charging cycle and the meaning of the “CHG” messages is as follows.
CHG1 The battery is very discharged and is being slow charged.
When sufficient charge has been put into the battery it will
switch to fast charge.
CHG3 The battery is being fast charged. When the battery is fully
charged it will switch to trickle charge.
CHG4 The battery is fully charged and is now being trickle charged to
maintain its charge.
A fully discharged battery will take around 7 hours to recharge.
9. MAINTAINENCE AND CARE
The NRT302 terminal has been designed to give reliable service in the
intended environment and is largely maintenance free.
9.1 BATTERIES
With normal use the expected life time of the supplied batteries is 500
charge/discharge cycles, after which they should be replaced. For optimum
performance it is recommended that the batteries be replace annually.
Page 15
O
9.2 KEYPAD
On no account should the keys of the terminal be pressed with sharp or
hard objects - including fingernails. Use of such objects may result in
premature failure of the keypad.

10.1 COMMUNICATION RANGE
Communication range is subject to local environmental conditions. The
NRT302 terminals are designed to have a typical communication distance
of 50m from a link unit in a glasshouse.
Communication range will be affected by local conditions and no guarantee
can be made of the actual communication range encountered in an
individual situation.
It should be noted that during periods of communication blackout the
terminal will continue to function normally (with the exception of feedback
and paging) and any entered data will be automatically transferred when
communication is re-established.
