Programming Tips
The following are some tips to help when programming the 7893.

Turn the host terminal Off or disconnect all interface cables to the 7893 before entering the
program. Some host terminals can corrupt the program if they are running and are
connected to the 7893 while entering the program.

To exit a Parameter Program without entering all the parameters, scan the Abort tag. Only
the parameter sequence which was aborted is not saved. Any prior sequence that
successfully ended with the scanner saying "Program Mode" is saved. To save the changed
parameters, scan the
Save and Reset tag.

To exit programming mode without saving any parameter changes, scan the Abort tag
while in Program Mode. The 7893 goes through initial startup and operates using the old
program.

If unknown how the 7893 is programmed, set all parameters to default values, then enter
any required changes. Do this by scanning the
Default tag first after applying power to the
7893. Next, scan the Program Mode tag to enter the Program Mode and enter the
programming changes.
Note:
Some parameters do not have default values and are not changed when the Default tag
is scanned.
