... Introduction Thank you for purchasing a TechTools product. We have made 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 or Mail and express your opinions. How To Reach TechTools You can reach us at any of the following : ...

... NOTE that this table shows the configuration information for all EconoROM II models. Some of these configurations may not apply to your particular model, depending on its capacity and data width. For example, an ER2-512- 64Kx8 emulator and therefore, can NOT be configured to emulate 16 bit or 128Kx8 and larger devices. ...

... DIP cables. Use the 28pin cable if you are emulating a 28pin EPROM; the 32pin cable if emulating a 32pin EPROM. 16 bit EconoROM IIs include a 40 pin cable for 16 bit DIP devices. If you are emulating PLCC type devices, you will need to purchase a DIP to PLCC adapter. These are available from TechTools as well as all popular adapter manufacturers. ...

... WILL DAMAGE THE EMULATOR! Run self-test Run ER2TEST.EXE. This file is located on the ERII Loaders Diskette. This self test will verify proper operation of the parallel port and all EconoROM II functions except the target interface buffers. If any of these tests fail, refer to the troubleshooting section for assistance. If the troubleshooting section does not resolve the problem, call our technical support people for help ...

... If binary is not an option, have the programmer store the file in Intel HEX or Motorola ‘S’ format. ER2LD.exe loads binary files into one or more EconoROMs. If your image file HEX format, use HEX2BIN.exe to convert it to binary before running the ER2LD.exe program. Both HEX2BIN and ER2LD are batchable, allowing fully automated loading of binary and HEX files ...

... The emulator senses target power and isolates its SRAM from the target power when the target is turned off. This permits safe target power cycling without the maintenance issues of batteries. The memory retention feature will work as long as the PC is powered up. EconoROM II User’s Manual 6 Copyright © 1996, TechTools ...

... Transfer speed set too high for this port. The transfer reliability is verified by the ER2TEST program. Make sure you are not trying to use a faster speed than the test program recommended. Also note that the test program tested the transfer speed to a single emulator. 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 ER2-1M can hold up to 1Mbit of data (128Kbytes). Any file larger than 131,072 bytes would overflow an ER2-1M. Look at the file size and verify that it is less than or equal to the emulator’s maximum size. ...

... For example, if the file is 60,000 bytes long, it would load into an ER2-512 and verify properly, regardless of the jumper settings. However if the emulator is configured to emulate a 27256, the target would see only the first 32Kbytes mirrored into both halves of the 64KByte space ...

... Low system voltage could behave in a similar manner possible that we could load and verify with a target voltage that is well under spec, but the target will not execute properly. EconoROM II draws more current than the EconoROM II User’s Manual 10 Copyright © 1996, TechTools ...
