Do I _REALLY_ need to connect the reset line?
This seems to be the biggest hurdle for first-time users. While the reset line may not be essential in some
specific cases, it is ALWAYS a good idea and OFTEN a requirement for consistent, reliable operation.
There is a lot to be said for consistency during debug! It is well worth the minimal time necessary to figure
out how to connect the reset line. It serves several functions:
- It keeps the target from running garbage immediately after the emulator is powered-up. The reset
will be automatically released after the first code download.
- It keeps the target from running garbage DURING a download or verify.
- It ensures the target gets a clean reset and starts running the new code after a download.
- It ensures proper power-up synchronization when the emulator is being powered from external
power and the target power is cycled.
- It makes the entire download/verify/run operation fully automatic and consistent.

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.
Can I use a longer target cable?
Maybe. We use ‘soft” drivers and 6” cables to minimize our impact on your target. This combination has
worked very successfully for us for nearly 10 years. Lengthening the cable increases the probability of both
cross-talk and line reflections.(depending on your target drivers’ rise-times). Longer cables also add
capacitance to the bus. If your target access times are considerably longer than ours (45ns), and/or your
drivers are fairly soft, you may be able to tolerate a considerable cable length increase. On the other hand,
if you need every last nanosecond of our access time and your bus has very fast rise-time drivers, you
should probably stick with our proven solution.
Can I use a longer Download cable?
Yes. You can use up to 25’ of download cable between the PC and the first emulator. However, we
recommend that you use the 12” daisy-chain cable provide to link multiple emulators together. This
provides a more ‘lumped load’ at the end of the line.
If you replace the flat cable, make sure the cable is wired 1-to-1. Most data cable is wired 1-to-1. Most
voice cable is wired reversed (1-to-8). If you extend the download cable by inserting a DB25M-DB25F
cable, make sure all 25 pins are connected.
