IMPORTANT INFORMATIO

NRT202

FCC ID: This device complies with part 15 of the FCC rules. Operation is subject to

the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Warning!

approved by Maynetronics Limited, will invalidate the authorisation of this device. Operation of an unauthorised device is prohibited under Section 302 of the Communications Act of 1934, as amended, and Subpart I of Part 2 of Chapter 47 of the code of Federal Regulations.

INTRODUCTION

The NRT202 data terminal is a hand-held wireless keypad and display for entry of numeric data. This terminal provides the primary data entry method of the NOMAD system.

Data entry is guided by menus displayed on the graphic display.

OOANRT202

Any modification or changes made to this device, unless explicitly

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.

NOMAD

PERATING INSTRUCTIONS

SETTING UP A TERMINA

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 num

ber. 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.

NRT202

L FOR FIRST USE

AGE

After inserting the batteries or removing the terminal from its charging station a startup message is displayed.

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 5

AGE

NOMAD

PERATING INSTRUCTIONS

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 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

NOMAD

PERATING INSTRUCTIONS

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.

NRT202

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

NOMAD

PERATING INSTRUCTIONS

The NOMAD system has distinct categories of barcodes so that the terminal can recognise whether the difference between clocking in operator one or entering task one. There are two types of task barcode. One is for entering the task there and then, for instance coffee break. The other is for selecting a task that will requires further information (such as a row or path number to indicate the operator s location) that will be entered later.

NRT202

6.3

Categories are

Clock in Clock out Enter task Select task Row/Path General

MAKING AN ENTRY

A typical sequence for operator 1 and task number 3, interrupted by task 100 might be as follows.

Scan clock in 001 label (in the canteen/entrance area)

Scan select task 003 label (in the canteen/entrance area)

Scan row label (in the glasshouse)

Scan row label (in the

Scan enter task 100 (in the canteen/entrance area)

Scan row label (in the glasshouse)

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.

6.4

The meaning of the task numbers depends on how the system has bee set up, task 3 might be to debreak.

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.

PERATING INSTRUCTIONS

It is also possible to use a combination of keypad entries and barcode entries. It might be desirable for the operator to use keypad entries for clocking in/out and selecting tasks and only using the barcode labels for the rows for instance.

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 barcode only mode is available.

BARCODE ONLY MODE

In barcode 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. Barcode only mode is indicated on the screen via BC in the top right corner.

NRT202

To activate/deactivate the barcode only mode the 0 and 2 keys should be held down while the start-up screen is shown (see section 2).

6.6

SUN SHIELD

For scanning in high ambient light environments, such as the glasshouse, the barcode labels should be fitted in the optional sun shields. It is also recommended that the sun shields should be used wherever possible as they also act as a guide to correctly position the terminal which minimises time lost to operators not correctly aiming their terminal.

ERROR MESSAGES

7.1

LOCK 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

Page 13

AGE

NOMAD

PERATING INSTRUCTIONS

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 entry is 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 NOT BE LOST IF THE BATTERY FULLY DISCHARGES.

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 in communicat 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.

ion range of a link unit to allow the system to extract the data

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.

The charging cycle and the meaning of the CHG messages is as follows. CHG1

CHG3 CHG4 A fully discharged battery will take around 7 hours to recharge.

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.

The battery is being fast charged. When the battery is fully

charged it will switch to trickle charge.

The battery is fully charged and is now being trickle charged to

maintain its charge.
