C.9 BASIC DATA TRANSFER OPERATIONS
The basic operations that can be accompiished with the
29B/handler system are:
• load the 29B's RAM with master device data
(section C.9.5)
• program devices with the 29B's RAM data
(section C.9.6)
• verify the 29B's RAM data against device data
(section C.9.7)
These operations may be performed on the handler from
either the 29B's keyboard or via CRC. This section
describes operational setup and basic data transfer
operations that are unique to the 29B/handler system. A
more detailed discussion of these data transfer operations
can be found in section 3 of this manual.
C.9.1 ENTERING CRC MODE (Optional)
If you are going to use a computer or a terminal to
perform operations with the system, enter select code F1
on the 29B to enter CRC mode.
To exit CRC, send the "Z" return command, or press any
mode key on the 29B's keyboard. See section 3.9.1 of this
manual for a more detailed discussion of the CRC format.
There are two remote handler commands specific to
computer remote control. A description of these
commands is given in table C-2.
Table C-2. Handler-Specific Commands (CRC Mode)
COMMAND
%
DESCRIPTION
This command puts the programmer
into a waiting state until the handler
indicates a start condition or the
operator presses the ST ART key on the
29B. Once the start condition has been
received by the 29B, it will output a
prompt
">"
symbol to the serial port
and wait for another command.
N
! This command instructs the handler to
distribute programmed and verified
devices to the number "n" bin, where
"n" is an integer from 1 to 4.
C.9.2 ENTERING FAMILY AND PINOUT CODES
Before you can perform any device-related operations \AJith
the Handler UniPak™, you must key in the family and
pinout codes of the devices you wish to program, The
codes may be entered from either the 29B's keyboard or
the terminal. Check the device table in section 1 of the
Handler UniPak™ manual and locate the two-digit family
and two-digit pinout codes of the device you wish to
program. To enter the family and pinout codes into the
system, follow the procedures given in section 3.4.1 of this
manual. After a family and pinout code has been entered,
it will remain in effect until the user changes it or power to
the 29B is shut off.
C.9.3 DEVICE INSERTION
Devices may be placed into the 29B/handler system at two
locations: 1) the performance board, and 2) the top of the
handler.
If you want to load the 29B's RAM with a master device's
data, or if you want to verify the 29B's
RAM
data with
master device data, insert a device into the performance
board's device socket. See section 3.4.2 of this manual for
device insertion procedure.
Insert devices at the top of the handler if you want to
program a device(s) or verify preprogrammed device(s).
When inserting devices into the Delta handler, insert pin 1
(notched end) of the device first. When using the MCT
handler, insert pin 1 last. Devices inserted backward will
cause a backward device error to display on the 29B
keyboard.
C.9.4 BINNING CONTROL
Front Panel Control
When programming or verifying devices from the front
panel, binning controls are defined as follows:
Bin 1: Device passes
Bin 2: Device fails-illegal bit
Bin 3: Device fails-failure during programming
Bin 4: Device fails-failed to verify after programming
NOTE
The Delta handler sends both program
and verify failures to bin 3.
