Device programmer with USB/parallel port connection
August 2003
PLCs, DCSs & Controllers
Needham's EMP-21 universal device programmer from ProMicro offers the user a choice of whether to connect to a PC via USB or via the parallel port. Supporting over 4000 devices and Windows-based software, the programmer's 'automated one touch' system allows the user to blank check, erase, program, verify or any combination of these functions.
The low profile, lightweight design of the EMP-21 allows it to fit in a briefcase and makes it practical for use on a desktop, proving useful for programming devices in the field. The comparatively 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. The only moving part on the EMP-21 is the Family Module, and that only moves when device families are switched.
The EMP-21 uses the new USB I/O scheme, so transfer times are greatly improved. The device programmer 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. 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 appropriate pins on different families of devices.
For USB connection, an IBM-compatible PC, Windows 98SE, ME, 2000 or XP is needed. For parallel port connection an IBM-compatible PC, Windows 95 and above, with 16 Mb of RAM is required. At least 40 Mb of free space is required and interface is via the USB port, or a standard parallel port.
