DS87000
Program Button
The Program button initiates a sequence of events that are specified by the current script (see “Script
Definition” section above). One of these events will be to transfer data from programmer's buffer memory
into the device's EPROM (that is, program the device). While these programming events are being
performed, the Busy light blinks. If an error occurs, the process is stopped immediately, and the Error light
begins flashing. If all operations are successful, the Complete light will flash.
By allowing the program button to initiate a script, complex operations may be performed in the absence of
additional equipment. This allows the programmer to be configured where a PC is conveniently available,
then easily carried to where the devices are actually programmed (possibly an assembly area) without the
need for additional equipment. Note that since the script settings are stored in non-volatile memory, the user
should verify them before a programming session to ensure the device(s) will be programmed as desired.
Like the Read button, the Program button must be pressed for 2 seconds before the programming function
begins. This feature protects against accidental initiation of the program operation.
Installation
System Software
The system software for the DS87000 is provided on a floppy disk. Copy the contents of the disk to the
desired hard disk directory or a working floppy disk and store the distribution disk safely for future use.
At the DOS prompt, enter the command "DS87000". This will start the menu driven system software. Using
the mouse or "hot keys" (shown on the menu), enter the DOS sub-menu and select the COM port to which
the programmer is connected. Communications with the programmer will begin automatically. The program
can also be started with the port number as a command line option. For instance, if the programmer is
attached to port 2, the command “DS87000 2” can be entered at the DOS prompt.
Hardware
Installing the DS87000 hardware consists of plugging the power supply into a wall outlet and connecting the
supplied RS-232 cable. The United States version of the programming kit (DS87000-000) includes a
standard 110 volt power transformer. A 220-volt transformer is provided with the DS87000-220 version of
the programmer. This transformer is equipped with a two prong cylindrical plug, and may require a
mechanical adapter for operation in some areas. The end of the transformer's cable contains a D.C. power
connector that plugs into the opening in the rear wall of the programmer. When power is applied, the red
LED will illuminate.
The programmer kit also contains an RS-232 cable with RJ11 connectors on both ends. Please note that this
is not a standard telephone cable, and replacing it with one may cause damage. Plug one end of the cable
into the mating connector on the top of the programmer. The other end of the cable should be plugged into
the supplied RJ-11-to-DB9 adapter. That adapter is then connected to an available serial COM port on the
PC. The DS87000 system software allows the use of COM ports 1, 2, 3, or 4.
