- HELP
EVDTC is a Level 2R, FUNCTIONAL diagnostic for the FEP
front end processor. It checks in link mode and requires
that diagnostic ZFPB?? is running in the PDP-11.
- SECTIONS
The program contains 3 sections.
DEFAULT- Tests 1 through 19. No operator action.
CONVERSATION- Test 20. Allows DMA parameter selection.
MANUAL- Tests 21 through 23. Requires operator action.
- DEFAULT
Starting the program with no section selected will run tests 1-19.
- CONVERSATION
This section contains one test. It allows setting up a DMA data
transfer in either direction. The transfer is repeated continuously
if the loop question is answered YES. Typing a control C is the
only way to get out of the looping if YES is anwered to
the loop question.
Default values:
WRITE TO PDP-11? NO
BYTE COUNT= 256
DATA PATTERN= 0 (FFFFFFFF)
THROTTLE CONTROL= 0
LOOP THE TEST? NO
Data patterns: (hex)
0= FFFFFFFF
1= 00000000
2= A5A5A5A5
3= 5A5A5A5A
4= FFFF0000
- MANUAL
This section contains 3 tests. They affect the PDP-11 operation
and require re-starting or re-loading the PDP-11 diagnostic.
- DEVICE
EVDTC tests the FEP option. It consists of an M8642 UNIBUS BRIDGE
MODULE on the VAX UNIBUS and an M8632 Q-BUS bridge module on the
LSI-11/23 Q-bus, or an M7484 UNIBUS bridge module on the PDP-11/24
UNIBUS, connected by cables.
- ATTACH
EVDTC must be loaded before it can be attached.
DS> LOAD EVDTC
Next, the device must be attached and selected. This can be done
using either the prompt mode or the explicit mode.
The VAX/VMS FEP Bridge Physical Access Driver (FPDRIVER) must be
connected before running this diagnostic. If it is not, consult
with the system manager, or check for instructions in EVDTC.DOC,
supplied with the diagnostic documentation.
- PROMPT
Prompt mode:
VAX 11/780 VAX 11/750
---------- ----------

- BRIDGE TYPE
The diagnostic has been designed to test both types of bridge hardware,
VAX/PDP and VAX/LSI. Each bridge has characteristics unique to the
SLAVE processor bus, either UNIBUS or Q-BUS, which will affect the
execution of some tests. Acceptable values are U or Q. There is no
default.
- SELECT
After attaching the UNIBUS adapter and the FEP, select the device
for testing:
DS> SELECT FPA
- QUICK
The quick mode is not used in this diagnostic. Program default
running time is about 30 seconds.
- SUMMARY
The summary section is not implemented in this diagnostic.
- EVENT
Event flags are not used by this program.
- MANUAL
See SECTIONS MANUAL.
- LOAD
The link diagnostic requires programs to be loaded in both the
VAX and the PDP-11.
- VAX
The VAX program must be loaded before attaching. It is loaded by:
DS> LOAD EVDTC
The PDP-11 diagnostic may be loaded after starting the VAX diagnostic
program if the DZ11 link is functional.
If the system does not recognize the DZ11 link logical name,
(created by the LOADER program), the operator may configure to the
serial line connected to the PDP-11:
NO VIRTUAL TERMINAL ASSIGNED TO LINK.
VIRTUAL TERMINAL(TTXY)?= TTA4
The following message results:
TO START THE PDP-11 PROGRAM, TYPE \ FOR ODT.
AFTER THE PROGRAM IS LOADED, TYPE >.
If no serial link exists and a console is connected to the PDP-11
the above question may be answered with a CARRIAGE RETURN. the
following message will be typed:
THE PDP-11 CONSOLE MUST BE USED.
LOAD AND START THE PDP-11 DIAGNOSTIC AND TYPE > WHEN DONE.
- PDP-11
The PDP-11 diagnostic ZFPB?? is loaded through the VAX diagnostic
if the serial link is present or through the PDP-11 console. In
either case, the console ODT is used to load and start the PDP-11
program. Example:
.R ZFPB??
DR> START
- CONTROL-C
Typeing a CONTROL-C from the VAX causes a BREAK to be sent to the
PDP-11 which enables console ODT. The VAX receives a CONTROL-C
which returns it to the Diagnostic Supervisor.
Typeing a "~" (tilde) sends a CONTROL-C to the PDP-11 which returns
it to the Diagnostic Run-time System.
Typeing a "\" (backslash) causes the PDP-11 to enter console ODT.
- RUN
The RUN command cannot be used with this program since the attach
must be done after loading the program and before starting it.
