Description
The DS87000 is a programming solution that provides a convenient, inexpensive method of programming
Dallas Semiconductor's family of EPROM-based Microcontrollers. The system comes complete with the
programmer, menu based PC software, power supply, and RS-232 cable. The programmer may be operated
in a stand-alone or PC hosted mode. Initially, a PC loads programming information into the DS87000. Once
loaded, there is no further requirement for the PC and the programmer may then be operated completely from
its front panel if desired. This allows the DS87000 to be easily moved to where it is needed. When a PC is
available, the DS87000 may be operated from the menu-based software provided.
Operations in front panel in stand-alone mode are initiated via the programmer's four push buttons. Three
lights (LEDs) provide feedback on system status. The convenient plug-in transformer provided with the
programmer supplies all necessary power.
When operated in PC-hosted mode, the user is offered full flexibility of the programmer through a system of
pull-down menus. All commands, options and menus are arranged to provide convenient access to each
command. The main menu screen is divided into DOS, Buffer, Encryption, Device, and Script Definition
menus. Each of these menus contains sub- for controlling various parts of the system.
The DS87000 also offers a unique feature typically found only in more expensive programming equipment.
This feature allows the DS87000 to write a unique identification number to every device programmed. After
initial conditions are established, the programmer automatically writes and subsequently increments a serial
number unique to each device.
The following sections describe operational details and installation procedures of the DS87000. The overall
programming environment is comprised of the programmer, the device to be programmed (or simply the
device), the system software, and the optional standard personal computer (PC).
