| The EMP-21 was the world’s first universal device programmer that uses both USB and the Parallel Port. With over 6600 devices supported and Windows based software all at an affordable price, the choice whether to connect to your PC via either USB or Parallel Port, is completely up to you. NEI’s all new “automated one touch” system allows you to blank check, erase, program, verify or any combination of these functions with the ease of pushing a button. The low profile, lightweight design of the EMP-21 makes it ideal for any desktop or briefcase, proving useful for programming devices in the field. The inexpensive cost of the EMP-21 lends well to a wide variety of budgets and with the absence of a fan or power switch, wear and tear is almost nonexistent.
PORTABILITY
The EMP-21 is extremely portable, you can pack it up and take it with you anytime you wish. At only 10 1/2" x 6 1/2" x 1 1/4", with a 2" high power transformer, the EMP-21 fits into a briefcase or toolbox with ease. The programmer, parallel and usb cable, transformer, and Family Modules, together weigh in at less than five pounds!
STABILITY
The EMP-21 carries a 1 year warranty on all parts and labor, and a 30 day money-back guarantee (restocking fee may apply).
The EMP-21 is static-protected at the ZIF Socket, Family Module socket, parallel and usb port, and power connector. The static protection on the parallel port also protects the parallel port on the EMP-21 from the 12 volts of a serial port.
It's case is made of tough .125" thick ABS plastic.
There is almost nothing to wear out on the EMP-21; no fan, not even a power switch. The only moving part on the EMP-21 is the Family Module, and that only moves when you switch device families.

FAMILY MODULES
Family modules are not an entirely new idea. They have been used in other programmers from time to time, to inexpensively route power and ground to the device. When you’re programming devices fairly slow, then straight slide-in connectors are just fine. However, the EMP-11 and EMP-21 program at speeds near the theoretical limit devices, so the digital signals traveling to the device must be clean, and the power and ground lines must be solid. Slide-in connectors can experience noise problems and higher resistance. The connectors that the EMP-11 and EMP-21 use are the same snap-in SIMM connectors that you may have holding the DRAM in your PC.
The purpose of Family modules is to allow us to use a few high quality pin drivers, instead of using a cheaper pin driver on each pin on the ZIF socket. This translates to cleaner, more manageable waveforms, at a much lower price.
