Chapter 1.Introduction

The BCP-760 is a programmable and flexible data collection device that can be utilized in a variety of data

acquisition applications. It can be used as a portable data entry device and it can also be used as a

programmable dedicated computer that receives and runs application programs downloaded from a host

computer.

The BCP-760 is controlled by a 16-bit INTEL 8088 compatible microprocessor, and has a 256K user

programmable FLASH MEMORY that includes a rich set of DOS functions and device drivers for application

development, including bar code decoding, display, keypad, communications, and real time clock/calendar.

The BCP-760 can be purchased with 2.5MB or 4.5M on-board RAM. All RAM memory is powered by the

main Li-ion battery and a back-up lithium battery, which retains the data stored in RAM and real time clock

when the main battery is drained. The BCP-760 has a 128x64 pixel backlit graphic LCD display, an integral

27-key keypad, a built-in bar code laser scanner/CCD module and an RS-232 serial port for data

communication with a host PC.

1.1 Programming

The BCP-760 system kernel includes three basic modules: 1. Device driver, 2. File manager and 3.DOS

manager. The BCP-760 terminal can be programmed using an E-PROM resident application program called

FormBuilder, Microsoft C, Borland C, Turbo C, Turbo Pascal and IBM PC macro assembler. The ROM

based firmware of the terminal provides emulated MS/DOS function calls. The programmer can design the

application programs by calling those functions just like in a DOS environment. The calling and parameter

passing conventions are compatible to that of MS/DOS and the programs are in the EXE format.

Programming details are included in the BCP-760 programming manual in these technical manuals.

The intelligence level of the terminal is determined by the configuration of the FormBuilder application or

supported language compiler. Once the program has been started up, the terminal operates as a stand-alone

unit, storing transaction data in the RAM disk area or linked to a host/personal computer.

1.2 Subsystems

The following describes several subsystems and related I/O interface functions, the DOS manager and file

manager functions. Detailed calling process is explained in the Programming Reference Guide included in

these technical manuals.

BCP-760 Operation Guide Page 4 of 31

1.2.1 Keypad Subsystem

The keypad subsystem scans the key matrix, converts the scan code to its associated key value and stores the

value in the keyboard input buffer for program utilization. The table below shows hexadecimal values assigned

to each key.

1.2.2 Display Subsystem

The BCP-760 display subsystem supports a character oriented 8-line by 20-character or 4-line by 16-

character LCD display. The origin (0,0) is always at the top-left hand corner. This subsystem provides the

program interface functions to display characters, set cursor position, get cursor position and clear screen

display.

1.1.1 Serial Port Subsystem

The BCP-760 terminal has an RS-232 serial port for data communication. The communication subsystem

consists of point-to-point protocol for general processing. The BCP-760 also supports a built-in Kermit server

for point-to-point communication.

1.1.2 Real Time Clock Subsystem

This subsystem allows users to set and obtain system date and time from the Real Time Clock Integrated

Circuit (IC) in the BCP-760.

1.1.3 Bar Code Input Port

The BCP-760 has a built-in barcode decoder. The terminal reads bar code labels through an integrated laser

scanner module or CCD module.

1.3 Diagnostics and Power-On-Test

The system diagnostic routines exercise the ROM validity check, test the RAM, system parameters, the keypad,

the real time clock, the RS-232 port, LCD and scanner port. The power-on-test is a subset of the system

diagnosis that only includes the ROM validity check, system parameter check sum test, and back-up battery

level check.

1.4 Application Module

Although applications run on the BCP-760 are classified into resident and transient categories, the BCP-760

operation cannot decipher the difference between them. The only difference is the location of the executable

files. For resident applications, the Job Scheduling EXEC "jumps" to the entry point in the EPROM and begins

execution. For transient applications EXEC "loads" the executable file from the RAM file into the RAM

memory and then begins execution.

1.5 Kernel Module

The BCP-760 kernel provides basic system services. The kernel module includes the DOS Manager, File

Manager, COM Manager and several interrupt service routines.

DOS Manager The DOS manager emulates most MS DOS function calls to control BCP-760 peripherals

and files.

FILE Manager The File manager implements a DOS-like file subsystem to support essential file operations.

COM Manager The COM manager controls the communication link between the BCP-760 and the host

through a RS232 serial port.

LOADER The function of the loader is identical to that of the MSDOS loader except for the memory

allocation/deallocation scheme being simplified. The loader's operations are:

1. read .exe header

2. find enough memory for .exe

3. read binary into RAM

4. relocation based on RAM allocation

5. set up all registers

BCP-760 Operation Guide Page 6 of 31

6. jump to the entry point

LCD Manager The LCD manager handles the cursor positioning and graphic pattern display. Two

character pattern fonts are supported. BCP-760 can support both 6x8 font (20 column by 8

lines) and 8x16 font(16 column by 4 line).

EXEC The EXEC is the job scheduler. It manages top-level operation flow of the BCP-760 system.

The EXEC program is analogous to the COMMAND.COM program in MS DOS-based

machines.

1.6 Operation Flow

The EXEC program controls the BCP-760. When the portable terminal is powered up, EXEC performs the

power-on-test (POT). EXEC proceeds to verify if the BCP-760 should make a warm or cold booting. A warm

boot resets the system without clearing any RAM program or data files. Device configurations preserve the

same values as they had before the warm boot. On the other hand, a cold boot will clear the RAM and

initialize the BCP-760 to default values.

The BCP-760 is always testing its main and backup batteries. The LCD will display a warning message when

the test fails.

Power on Test Test failure message

Main battery test "WARNING MAIN BATTERY LOW"

Backup battery test "WARNING LITHIUM BATTERY LOW"

When the main battery is low, a warning message will be displayed on the LCD when BCP-760 is power on.

For BCP-760, it can automatically detect battery status, a warning sign will be display on battery icon on the

upper side of LCD.

During the start-up process, EXEC also initializes the BCP-760 barcode scanner and RS232 communication

port, and creates all dynamic data structures; e.g. keypad queue and COM buffer. Once the initialization

procedure has been completed, EXEC checks if a supervisor menu has been requested. The supervisor menu

can be requested if the operator holds down both [CMD] and [] keys while powering up the BCP-760.

NOTE: 1) Cold start, will clear all data stored in the RAM and reinitialize the portable terminal to

system default.

2) There are two system flags, “Start” flag and “Save NOT OK” flag, which will be verified

each time the unit is turned on.

3) When the “Start” flag verification fails, it indicates that there is probably a defective RAM

chip or that the backup battery power is low. A data back up and hardware diagnostics are

recommended in these cases.

4) The “Save NOT OK” flag is used to check if the previous turn-off process was made

normally or not. The system will not return to the last turn-off point if the “System Resume”

is set to On when this flag verification fails.

A program downloaded to the BCP-760 may be automatically executed each time the portable terminal is

turned on. In order for the program to be auto-ran, it must be downloaded to BCP-760 with the name

AUTOEXEC.EXE. When the BCP-760 is turned on, the system will scan the file directory and execute the

program, otherwise it will enter a mode of operation called the READY mode. In this mode, the BCP-760

will standby for keypad-entered commands, or commands from the Host PC.
