Programming Tips

•Turn the host terminal off or disconnect all interface cables to the NCR 7870 before entering your program. Some host terminals can corrupt your program if they are running and are connected to the NCR 7870 while you are entering the program.

•To exit a Specific Programming Mode without entering all the parameters, scan the Abort tag. All parameters entered are retained and the NCR 7870 returns to the Base Programming State. To save the changed parameters, you must scan the Save and Reset tag.

•To exit the programming mode without saving any parameter changes, scan the Abort tag while in the Base Programming State. The NCR 7870 goes through initial startup and operates using the old program.

•If you do not know how your NCR 7870 is programmed, set all parameters to default values, then enter any required changes. Do this by scanning the Default tag as the first tag after applying power to the NCR 7870. Next, scan the Programming Mode tag to enter the Base Programming State and enter your programming changes.

•After completing a programming sequence, wait for the tone or Voice Message to indicate the unit is back in Programming Mode before beginning the next programming sequence.

Note: Some parameters do not have default values and are not changed when you scan the Default tag.
