Introduction
The PT630 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 PT630 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 PT630 can be purchased with
512K, 1.5MB, 2.5MB, 3.5MB 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 PT630 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 PT630 system kernel includes three basic modules: 1. Device driver, 2 File manager and
3.DOS manager. The PT630 terminal can be programmed using an E-PROM resident application
program called FormCaching, a Windows-based, high-level application generator JobgenPlus,
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 PT630 programming manual in this binder.
The intelligence level of the terminal is determined by the configuration of the FormCaching
application or the downloaded program generated by JobgenPlus or supported language compiler.
