IV. Storing Bin Assignments in Handler Memory:
The handler uses a look-up table to assign handler output bins/tubes to tester sort signals. The output
tube parameters are stored as a two digit hexadecimal number in the handler’s memory (e.g.: “E5”). The
first digit describes what happens with tubes numbered five through eight, and the second digit describes
what happens with tubes numbered one to four. The first digit is called the “Most Significant Bit” and the
second, the “Least Significant Bit.”
You will need to edit the memory addresses in the handler’s battery backed-up RAM to store your desired
binning data. A chart with all relevant memory addresses is shown at the end of this document and on the
Test Signal - Bin Sort Data Worksheet.
To edit the Handler memory from the front panel display, follow this procedure:
1.0
Make sure you have a copy of the E
XATRON
-supplied RAM address listing for your system. While
most handlers store the binning information as described in the chart on the worksheet, some custom
handlers have variations in addresses. A copy of this address listing is in the supplemental chapter at
the end of this manual.
2.0
Verify that the handler is in Manual Mode. Display will read
MANUAL MODE
.
3.0
Press the
[SET UP]
key. Display will read
CHANGE RAM ? NO
.
4.0
Press the
[SET UP]
key. Display will read
CHANGE RAM ? YES
.
5.0
Press the
[Enter]
key. Display will read
LOAD DEFAULT ? NO
.
6.0
Press the
[Enter]
key. Display will read
0090 DATA 01
The handler is now in the edit mode of the
handler’s battery backed-up RAM.
7.0
Press the
[SET UP]
key to increment the address. The
[TOTALS]
key will decrement the address.
8.0
Press the
[SET UP]
key until address
00C0
is displayed. Display will read
0C0 DATA xx
, where
xx
is the hexadecimal data at that address. Address
00C0
is the address where data for Sort Signal 1 is
stored on standard handlers. Note that LEDs on the output door are now flashing. The flashing lights
indicate which tubes are currently selected for Sort 1. If you change the data, the flashing lights will
change as well. Use this visual confirmation for the tubes you have selected.
9.0
If necessary, change the data at this address:
9.1
Press the
[Space]
key to increment the first data digit (the most significant data bit.)
9.2
Press the
[Delete]
key to increment the second data digit (the least significant data bit.)
9.3
Press the “
[0]
” key to set the data at that address to 00.
9.4
Press the “
[ – ]
” key to set the data at that address to FF.
9.5
Press the
[Clear]
key to load the EPROM default data at that address.
10.0
When finished editing this address, press the
[SET UP]
key until the next relevant address is
shown. Consult the handler memory address chart below.
11.0
Edit this address as described above in section 9.0.
12.0
Continue this process until all addresses have been changed to proper data. Note that if your
tester/programmer uses less than eight signal outputs, you should assign the fail bin to all
remaining sort signals.
13.0
When finished editing, press the
[Enter]
key to exit editing and set the new DATA into RAM.
