... Introduction Thank you for purchasing a TechTools product. We make every attempt to provide quality tools at reasonable prices. If you have any questions, comments or suggestions, please feel free to contact us by FAX, Voice, email or mail and express your opinions. How To Reach TechTools You can reach us at any of the following : ...

... If the floppy contains a PATCH, you will be instructed to install the software from the CDROM and THEN apply the patch. If the floppy contains a full install, the CDROM is not needed and any ER3 software it contains is out- dated. We still include the CDROM because it contains a wealth of information. ...

... EPROM EMULATOR in backwards, it applies reverse voltage to the device or emulator, causing permanent damage. If your target uses DIP sockets or a TechTools’ PLCC adapter fairly easy to ensure the cable is plugged in properly. Simply check (twice) that the RED stripe on the cable is aligned with the PIN 1 end of the socket ...

... If you are not sure, ask ‘sparkie’ (a technical term for the hardware engineer that designed the board). Call our technical support if you are unsure about which output to use or where to connect to your target. EconoROM III User’s Manual 4 Copyright © 2000, TechTools ...

... If your target operates at less than incapable of supply the extra emulator current, then you must use an external power supply. External power supplies are available from TechTools or your local dealer. The external supply must provide a regulated 5VDC at 300ma or greater. ...

... RESET to keep the target from running until it has received a download. The flashing GREEN LED indicates target activity. - Verify the RESET line is connected - Verify your selection of the RESET attachment point - Verify your selection of RESET polarity.

... If you are using multiple EconoROM IIIs, we recommend that you test them collectively to ensure reliable operation in the final configuration. Type “ER3TEST32” to run a full speed test over printer port 0x378. You can change the printer port by using a /P parameter. For example, if your emulator is connected to a printer port at 0x3bc, you would enter “ ...

... This establishes a solid base-line. You can always come back to this file to verify everything is functioning (except perhaps your last code revision). If you choose to use the ER3LD32 program, run it without parameters to see a simple help screen. You can also refer to the section below on ER3LD/ER3LD32. ...

... ER3LD and ER3LD32 load binary and HEX files into one or more emulators. They can also perform a VERIFY-ONLY if you suspect that the emulator contents have been corrupted. ER3LD32 uses our ring-0 drivers to access the low-level printer port registers. It works under ALL 32 bit versions of Windows (including NT and 2000). ...

... EXAMPLE 1 If you have two emulators daisy-chained together, and wish to split a file between them, you would specify: “ER3LD filename /e2 /f1”. The /f1 is optional since the default is start with emulator #1. The /e2 parameter tells the loader that two emulators are involved in this transfer. ...

... The self-test program does a reliability test at a specified speed setting. Re-run the ER3TEST program with a faster speed setting (lower /Dx number). If the reliability test shows that the system is reliable at this speed, you will be able to use this same parameter on the program. EconoROM III User’ ...

... Troubleshooting The distribution software contains a test program called ER3TEST32.EXE. ER3TEST32 verifies the port address, its reliable at the selected transfer speed and the emulator’s functionality as well as proper installation of the ring-0 drivers. The first step in troubleshooting is to run this program and make special note of any problems it reports ...

Page 17

... The ER3TEST program verifies transfer reliability. Test the desired transfer speed reliability with “ER3TEST /dx” (where x is 0,1,2,3 or 4). /d0 is the fastest setting. If you are daisy-chaining several emulators, their combined load can slow down the printer port rise times, resulting in a need to slow down the transfer speed to avoid over-running the port signals ...

... The file may be too large for the emulator, causing the data to wrap-around truncated. For example, an ER3-1M can hold up to 1Mbit of data (128Kbytes). Any file larger than 131,072 bytes would overflow an ER3-1M (as well as a 1Mbit EPROM/FLASH). Look at the BINARY file size and verify that it is less than or equal to the emulator’s maximum size. ...

... DIP to 32 pin PLCC adapter. Smaller devices usually need a 28 pin DIP to 32 pin PLCC adapter but MIGHT need the 32 pin version. Give us a call if you are not sure. EconoROM III User’s Manual 15 Copyright © 2000, TechTools ...

... EconoROM III draws more current than the EPROM it is replacing. The target may be able to supply enough current during downloads, but may not be able to hold the voltage up when it starts running, causing power fluctuations or noise. EconoROM III User’s Manual 16 Copyright © 2000, TechTools ...

... The 16bit software will sometimes work on these systems, but through a virtualization mechanism that is VERY slow. Our 32bit software uses ring-0 drivers to access the hardware at about 2.5Mbit/sec. Use Quickloader or ER3LD32.EXE. If these tips did not solve the problem you are experiencing, please contact our technical support people at support@tech-tools ...

... Can I use EconoROM III target? YES, but you will need an external power supply. Connect 5VDC at 300ma or greater to the emulator’s external power connector. External power supplies are available form TechTools. What is the lowest target voltage supported? EconoROM III was designed to support 3.0V to 5.0V targets. However, it CAN support lower voltage targets within limits. Three things set the lower limit ...

Page 23

... Can EconoROM III emulate DIP/PLCC/TSOP… packages? Yes. TechTools stocks low cost PLCC adapters and all emulators ship with DIP cables. We find that DIP and PLCC packages cover about 95% of our customers’ needs. For other packages, we refer you to the standard adapter companies. They can provide adapters for all common EPROM, SRAM and FLASH devices ...
