Connecting 865 to the PC
Switch off PC and programmer. Insert the communication
cable included with your 865 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, though it is not recommended to
operate the 865 programmer through a mechanical printer
switch. Use of an electronic printer switch is impossible. But
you can install a second multi-I/O in your computer, thus
obtaining a supplementary printer port, says LPT2. So your
printer may remain on LPT1 while the programmer on LPT2.
Switch on the PC.
Connect the mains connector of the power supply (or the wall-
plug power supply itself) to a mains plug, and then connect the
mini-DIN connector to the programmer's connector labeled
"12VAC". At this time all 'work result' LEDs (and 'POWER'
LED) light up successive and then switch off. Once the
POWER LED lights with low brightness then the 865
programmer is ready to run.
Next run the control program for 865.
Caution! If you don't want to switch off your PC when
connecting the 865, 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 865'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 .
Note: Programmer's protection electronics protect the target
device and the programmer itself against either short or long-
term power failures and, partly, also against a PC failure.
However, it is not possible to grant the integrity of the target
device due to incorrect, user-selected
programming
parameters. Target device may be not destroyed by forced
interruption of the control program (reset or switch-off PC), by
removing the physical connection to the programmer, but the
content of actually programmed cell may remains undefined.
Don't unplug the target device from the ZIF socket during work
with devices (LED BUSY shine).
