INSTALLATION INSTALLATION
CONNECTING MP AVR-51 TO THE PC
Please refer ro figure 4. Switch off PC and programmer. Insert the communication cable included
with Your MP AVR-51 programmer package to a free printer port on your PC. If Your computer
is equipped with only one printer port, substitute the programmer cable for the printer cable
Connect the opposite cable end to the programmer. Screw on both connectors to counter-connectors.
This is very important. It may be uncomfortable to switch between printer cable and programmer
cable, but it is not possible to operate the programmer through a mechanical or an electronic.
However You can install a second multi-I/O in your computer, thus obtaining a supplementary
printer port, say LPT2. So your printer may remain on LPT1 while the programmer on LPT2.
Connect the mains connector of the power supply (or the wall-plug power supply itself) to a mains
plug, then connect the mini-DIN connector to the programmer’s connector labeled “12VDC”. Then,
on the programmer lights up LED POWER and the programmer MP AVR-51 is ready to run. Next
switch on the PC and run the control program.
! CAUTION !
If You don’t want to switch off your PC when connecting the programmer, proceed as follows:
- When connecting the programmer to the PC: FIRST insert the communications cable and
THEN the power-supply connector.
- When disconnecting the programmer from the PC: FIRST disconnect the power-supply
connector and THEN the communication cable.
From programmer’s point of view the connecting and disconnecting sequence is irrelevant.
Protection circuits on all programmer inputs keep it safe. But think of your PC, please.
PROBLEMS RELATED TO MP AVR-51 TO PC CONNECTION
Due a large variety of parallel port types, a case may occur when the programmer cannot “get
concerted” with the PC. This problem may be shown as none communication between the PC and
the programmer, or by unreliable communication.
- If this behavior occurs, try to connect your programmer to some other PCs or other parallel ports
near you.
- Please remember that the printer port where the programmer is connected must be configured
as Centronics compatible. You should check in the BIOS configuration of Your computer that
the port is set as compatible (or standard, or normal, or SPP, according to the BIOS
manufacturer, all these denominations refer to the same setting for the parallel port), or, if You
use a multi I/O card, assure that it can be configured and used as Centronics compatible.
If You can't find any solution, please contact
grifo ®
directly. Provide us an accurate description of
Your PC configuration, including some other circumstances bearing on the problem in question, and
advise the manufacturer of your problem. Don’t forget please to tell PC type, manufacturer, speed,
operating system type and version, resident programs; your parallel port I/O manufacturer and type.
