- TRAKKER TROUBLESHOOTING GUIDE
-
- Parallel Port Usage Codes:
- Some parallel ports will not handle the faster default
- settings and you may need to slow them down using the tape
- configuration program. To reset the parallel port codes, go
- to the tape (or Trakker) subdirectory. Type CD\TAPE (or
- CD\TRAKKER). Then to start the program, type config from
- the C:\TAPE prompt (or C:\TRAKKER prompt) and then press
- ENTER... for example:
-
- C:\TAPE>Config (press ENTER)
-
- This will load the tape configuration program and you will
- then need to select hardware configuration. Answer the
- questions and look for the question that asks, "DO YOU WANT
- TO PERFORM ADVANCED OPTIONS?" The next screen will say,
- "Please note your parallel port(s) type:." It may say
- something like, "LPT1 Parallel Port Type: Unidirectional."
- Then go into the next screen that will say PARALLEL PORT
- USAGE: 2. It will usually default to 2 for Unidirectional
- parallel port or a 5 for Bidirectional parallel port. Either
- way, you will want to test your system by slowing down the
- parallel port usage to 0 on a Unidirectional parallel port
- or 4 on a Bidirectional port. If it works on a
- unidirectional port, you may want to try setting number 1 to
- see if it will run faster. Listed below is a brief summary
- of the codes by parallel port type.
-
-
- Unidirectional Bidirectional
- Fast 2 5
- Slow 1 4
- Slowest 0

-
- The following is a list of suggestions for ERROR 194, ERRORS 122
- and 123, ERROR 90 and optimizing your backup.
-
- ERROR 194
- 1. Make sure the power plug is all the way in the Trakker.
- If the drive comes on when a tape is inserted, it is
- getting power.
- 2. Make sure the data cable is plugged into your parallel
- (LPT) port and not your serial port.
- 3. Make sure the data cable is plugged in securely and
- oriented properly.
- 4. Make sure the data cable is plugged into the port
- marked "To Computer" on the Trakker.
- 5. Try plugging the Trakker directly into the PC if you
- have a parallel switch box, or any other parallel
- devices installed.
- 6. If you have documentation on your parallel port card or
- documentation on your computer system, verify that your
- parallel port interrupt is set to IRQ 5 or IRQ 7 and
- the parallel port address is set to 378h, 278h or 3BCh.
- You can usually enable the hardware interrupt, change
- the hardware interrupt or set the parallel port address
- by changing jumpers on your parallel port card, or by
- making parallel port changes through your CMOS setups.
- In some cases the interrupt and/or address may not be
- selectable at all. Refer to the documentation for your
- parallel port or the documentation for your computer
- system for more information.
- 7. If your Computer system is a PS/2 check the following:
- PS/2:
- Some PS/2s are equipped with a "processor type 2" that
- allows for IRQ sharing (Arbitration levels). The
- Parallel Port Arbitration level is found in the CMOS by
- pressing Ctrl-Alt-Insert simultaneously at bootup or by
- booting with the reference diskette.
- 1. On some PS/2s the "Parallel Port Arbitration"
- level choices are 0-7 and Disabled. Set the
- "Parallel Port Arbitration" level to
- Disabled.
- 2. On some PS/2s the choices for Parallel Port
- Arbitration levels are 0-7 only, and the
- arbitration level cannot be Disabled.
- Trakker is unable to operate on these
- systems.
- 8. Reinstall your Trakker software. First delete the files
- in the Tape directory and then run the "Install"
- program from your Trakker Software installation
- diskette. There is a QICFAX document available on
- de-installation of the Colorado Backup for DOS and
- Colorado backup for Windows software.
- 9. Try a different parallel port or install another
- parallel port card.
- 10. See Calling Technical Support at the end of this
- document.
-
- ERRORS 122 and 123
- 1. Clean boot your PC (refer to the end of chapter 6 in
- your Colorado Backup manual for help) to eliminate TSRs
- (see TSR in the Glossary of your Colorado Backup manual
- for an explanation of TSR). TSRs loading in your
- CONFIG.SYS or AUTOEXEC.BAT files can interfere with
- Trakker operation. If the Trakker operates with a
- "Clean Boot" you can then add TSRs back into the
- CONFIG.SYS or AUTOEXEC.BAT files one at a time until
- the Trakker will not operate. This will pinpoint the
- conflicting TSR which may need to be removed. Another
- option is to "Clean Boot" with a floppy disk when you
- want to use the Trakker.
- 2. Change the "Concurrent disk/tape operation" in the
- software setups to "N" or delete the "X".
- 3. Change the parallel port usage to 0, if the problem is
- corrected increase the usage number until you find the
- optimum setting.
- 4. Turn Off your turbo switch or, Turn On your turbo
- switch.
- 5. Reinstall your Trakker software, by first deleting the
- files in the Tape directory and then running the
- "Install" program from your Trakker Software
- installation diskette. There is a QICFAX document
- available on de-installation of the Colorado Backup for
- DOS and Colorado backup for Windows software
- 6. If you are comfortable and understand your CMOS setups
- (settings generally apply to 486DX systems):
- a. Verify your bus timing is set to 8-12 Mhz.
- b. Turn off 486 cache -- With Trakker Software 3.04
- and above this can be done with the "/Y" switch.
- 7. If your computer is an IBM PS/2 with a processor type
- 2, set IRQ 7 and IRQ5 to "Dedicated" in the IBM system
- setups.
- 8. Try a different parallel port or install another
- parallel port card.
- 9. See Calling Technical Support at the end of this
- document.
-
- ERROR 90
- 1. Enable the hardware interrupt on the parallel port.
- (see step 6 under error 194)
- 2. Change the hardware interrupt on the parallel port.
- (see step 6 under error 194)
- 3. Repeat the steps for Error 122 and 123.
-
- Tips to optimize backup times
- 1. Use the "Optimize Time" option for compression when
- doing a backup.
- 2. If using DOS 5.0 or above, load DOS high (see your DOS
- manual for information).
- 3. Load high as many device drivers and TSRs as possible
- (see your DOS manual for information).
- 4. Run the software from the command line or in a batch
- file (see your Colorado Backup manual for information)
- 5. Use the /-p option from command line to disable
- printing of files to the screen.
- 6. Try turning Turbo on if it is currently off.
- 7. Set the "Sort Type" to "No Sort" in the Tape software
- setups.
- 8. Add buffers to your config.sys file.
-
- Approximate Backup Speeds
- The following chart is an estimation of the backup times we have
- seen in our testing of different classes and speeds of CPUs.
- Your backup times may vary due to free memory, hard drive access
- time, hard drive optimization, data set and data compression.
- Backup times will usually be slower when using data compression,
- except on faster CPU's.
-
- CPU/Speed Approx. MB/Min
- 286/12 1.5-2.5
- 386/16 2.0-3.0
- 386/20 2.5-3.5
- 386/25 3.0-4.0
- 386/33 3.0-4.5
- 386/40 4.0-6.0
- 486/20 3.5-4.5
- 486/25 3.8-4.8
- 486/33 3.8-5.8
- 486/40 4.0-7.5
- 486/50 4.0-8.0
- 486/66 4.0-9.5

-
- Using the "Print Dir" option with Trakker
- If you have only one parallel port in your computer, and
- your printer and Trakker are installed on the same port, you will
- not be able to print the tape directory from the Trakker
- software. You can print to a text file and dump that file to hard
- copy after exiting software. If you have at least two parallel
- ports (LPT1, LPT2, LPT3), then Trakker and the printer must be
- installed on separate parallel ports in order to print the tape
- directory from the Trakker software.
