Overviewof the PTC-960X

The Telxon PTC-960X is a battery-powered,hand-held computer used to collect, store, andtransmit data. The PTC-960X has a built-in bar-code scanner. Options for transmitting data overtelephone lines and printing are also available.The PTC-960X automates your data collectionprocedures and is custom programmed to effi-ciently handle your organization’s unique datacollection applications.

The PTC-960X is designed for use in areaswhere dust, dirt, or moisture can be excessive.The PTC has been specially sealed to resist thesehazards.

Because the PTC-960X is custom programmedfor each organization, this manual does not in-clude the specific operating instructions for yourorganization’s unique PTC data collection pro-gram. Operating instructions and training foryour PTC’s application program should be avail-able from your supervisor.

The PTC runs an application program speciallydesigned to collect data for your organization.This program leads you through the applicationwith a series of display messages, prompts, andbeeps. Messages tell you when you make anerror and provide information on the applicationor the PTC’s status. Prompts and beeps tell youwhen to enter data, what type of data to enter,and when you complete certain operations.

ÄÄ

12

© Entering data

You can enter data into the PTC-960X usingeither the keyboard or the built-in scanner.When you press a key on the PTC’s keyboard,the corresponding number or letter appears onthe display. Pressing the ENTER key stores thedata in the PTC’s memory.

The built-in bar-code scanner can “read” a barcode. A bar code is a series of vertical bars andspaces that you find on nearly every item inbusiness today. The PTC interprets the scanneddata, may show this data on the display, and canstore the data in the PTC’s memory.

© Communicating data

After collecting the data, the PTC must eithertransmit the data to a host computer for process-ing or send it to a printer, or both, to make thedata useful to you and your organization. ThePTC-960X is capable of transmitting datathrough an optional communication cradle or bybeing connected by cable to a host computer,printer, or other accessory.

© Flash programming

The PTC-960X contains a flash EPROM, whichis an electronic chip that contains the PTC’sapplication program. The flash EPROM can bereprogrammed (flashed) while it is inside thePTC, making updating and changing applicationprograms easy.

Programmingthe flash EPROM

The application program instructions for yourPTC-960X are stored in an electronic componentinside the PTC called a flash EPROM. This is atype of read-only memory, but unlike standardEPROMs, flash EPROMs can be erased and re-programmed while they are inside the PTC. Thisallows you to update your application programquickly and easily.

To write over existing programs on the PTC’sapplication flash EPROM, you must connectyour PTC to an MS-DOS-based personal com-puter and then run the FLASHPC.EXE utility todownload the special file (ROM image file) con-taining the new application.

© Before you begin

Make sure the PTC’s battery pack is fullycharged. If the battery pack runs low, the repro-gramming process will abort. You will lose theapplication program already in the PTC.

The following procedure assumes

• you are familiar with operating an MS-DOS-based personal computer,

• you have read the “Communication andconnections” section on page 29,

ÄÄ

41

• you will connect the PTC’s downloadcable to the personal computer’s COM1serial port,

• you will use the default settings for theFLASHPC.EXE utility, and

• you will run FLASHPC.EXE in interac-tive mode.
