Interchange: “LOCN xxx1 yyy1”, “OR”, “LOCN xxx2 yyy2”:
If interchange has occurred between two nets of two points each, tester cannot
locate exact interchanged point. It displays both possible interchanges.
Open group: “OPEN xxxx yyyy”.
In case of two point net from ‘xxxx’ to ‘yyyy’ or if some wires with point ‘yyyy’
from a circuit starting with point ‘xxxx’ get disconnected. Check only for “yyyy”.
Short group “SHORT xxxx yyyy” etc.:
If a circuit / net with first point ‘xxx’ get shorted with a circuit / net with first
point ‘yyyy’.
Extra point “EXTRA XXXX”.
If a point is not in the net list but it is connected to tester.
4.5: Interfacing Printer:
•
A standard centronics port on DB25 F i.e. 25 pin D type female connector is
provided. It can be connected to any standard centronics printer available such as dot
matrix, ink jet, laser or bar code printers.
•
Label printing is added to print a label on every passed harness. Data to be
printed on every pass can be different for each cable number, 25 different data can be
stored in tester’s memory. For each cable type 1024 bytes are reserved for label data.
•
A complete label can be printed or if standard label is pre-printed then only
variable data can be printed.
•
Tester can print variables viz. Date, time, week, month and year of testing. To
print these in label data, at the place where date is to be printed, “@ 1” should be placed
and for time “@2” is to be placed etc.
•
To print special characters or bar codes, first of all printer has to be finalized.
Label or bar code printers accompany label printing software which generates an ASCII
file to be sent to printer for printing required data. Same file can be used by a little
modifications such as adding “#” characters at the start as well as end of the data and
adding character @ followed by required number, at required places for printing date and
time.
