CERTIFICATION 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. 2. INTRODUCTION The NRT102 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 16 character by 2 line display. The terminal is powered by a rechargeable battery with a built in charger that draws DC power from a charging adapter. In an emergency the rechargeable battery may be replaced by a standard PP3 providing no attempt is made to charge the unit while fitted with the non-rechargeable 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™ - NRT102 O PERATING INSTRUCTIONS PAGE 4 of 10 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 loaded into the terminal. 3.1 ENTERING A NODE NUMBER After inserting a battery or removing the terminal from its charging bracket a startup message is displayed. While this message is displayed hold the 3 and the 9 keys down until prompted with the message “Enter node”. 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 199. It is these three digits that identify the terminal on the system. 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 ab…

TECHNICAL DECRIPTION FOR NOMAD NRT102-2 TERMINAL The NOMAD system comprises a PC, a controller, multiple link units and terminals. The controller connects to the PC via a RS232 link. A RS485 bus connects the controller to the link units. Each link unit has a low powered UHF transceiver which communicates with the terminals. The number of link units depends on the size of the site. The aim of the whole system is to get data from the terminals onto the PC. The NRT102-2 terminal is a battery powered device consisting of a numeric keypad, a 2 line by 16 character reflective LC display and a wireless link to the NOMAD system. Data entry is guided by menus which are downloaded from the NOMAD system. The terminal is optimized for job logging of personnel and is essentially an electronic time sheet. A small embedded processor with a 1MHz clock provides all the peripheral and control features. An on-chip UART interfaces to the RF section. Data and menus are stored a 64k bit serial EEPROM with an I 2 C interface to the processor. The 4x4 matrix keypad is connected to the processors peripheral pins with the strobe lines sharing the same pins as the data bus for the display. A piezo sounder provides audible response to keypad presses and other abbuciations. Power is supplied from a 8.4 volt NiMH rechargeable battery which is recharged under the control of the processor. The battery is followed by a linear regulator which steps the voltage down to 5 volts. An op-amp and a few discrete components form the charging circuit which charges at 3mA or 22mA. The wireless section is centered around a TR1000 hybrid transceiver from Radio Monolithics. This device contains all the necessary RF circuitry with just a few passive components, a 3.3V regulator, and a couple of transistors to perform level shifting of the logic signals. The antenna is a loop type integral to the PCB. Operating frequency is 916.5 MHz and the modulation type is OOK.
