LabProg+

Introduction

LabProg+ is a universal programmer that supports
programmable integrated circuits or devices manufactured in
various technologies. Powerful internal pin-driver electronics
controls logic levels, pull-up/pull-down, clock, ground, one
power supply and two programming supplies and is able to
read all 48 pins independently. This advanced design gives
LabProg+ the ability to handle almost every programmable
device in DIL package up to 48 pins without any adapters
and/or family modules. This design philosophy allows ELNEC
to easily add new devices to the device list, giving you the
freedom to implement the optimum device in your designs.
LabProg+ is also a tester of TTL/CMOS logic circuits and
various memories. Furthermore, it can generate user-definable
test pattern sequences. LabProg+ is a true universal and a
true low-cost programmer, providing the best "value for money"
in today's market.
LabProg+ works with the IBM PC 486 compatible or higher,
portable or desktop personal computers. No special interface
card is required to connect to the PC since LabProg+ uses the
standard parallel printer port. The LabProg+ control program
also supports bi-directional protocols for the parallel connection
to the PC printer port providing fast and reliable
communication speed.
The programmer has on-board intelligence and is controlled by
powerful microcontroller system and support devices.
LabProg+ has been designed for multitasking operating
systems and is able to perform time-critical programming
sequences independently of the PC operating system status
and without being interrupted by any other parallel process
running on the PC. Consequently, LabProg+ works without any
problem on systems running Windows 95/98/Me/NT/2000/XP.
LabProg+ performs device insertion test (wrong or backward
position) and contact check (poor contact pin-to-socket) before
it programs any device. These capabilities, supported by
current limit protection and signature-byte check, help prevent
chip damage due to operator error.
Built-in protection circuits help prevent damage of the target
device due to mains supply fluctuations, communication errors
or if the PC operating system fails. In the event of such errors
the LabProg+ performs independently of the PC exactly
specified special sequences so that the target device remains
intact. LabProg+ performs selftest (diagnostic tests), including
verification of pin-driver voltage/level, for accurate timing of the
