- HELP
EVDFM-1.0, a FUNCTIONAL level (Level 2) diagnostic, contains a series
of tests which will establish the functionality of the DR70 under VMS.
The program provides error messages which identify data and I/O
errors. The program runs with the Diagnostic Supervisor from any
terminal in a Level 2 (VMS) environment, after installation of the
special DR70 diagnostic driver.
- DEVICE
This program (EVDFM) supports the following devices:
Device: DR70
Link: UR
Recommended Generic: URdu
- DRIVER
This program requires that the special purpose DR70 diagnostic driver
be installed before execution of this diagnostic. The DR70 diagnostic
distribution media contains the files necessary to generate the driver.
Ask the client's personnel to install the driver from the instructions
found in the file URLOAD.COM on the distribution media.
- EVENT
Not Applicable.
- QUICK
Not Applicable.
- SUMMARY
None.
- ATTACH
Load the diagnostic before attempting to attach.
For the VAX 11/780:
DS> ATT[ACH] RH780 HUB RHn tr br<CR>
DS> ATT[ACH] DR70 RHn URcd m<CR>
For the VAX 11/750:
DS> ATT[ACH] RH750 HUB RHn br<CR>
DS> ATT[ACH] DR70 RHn URcd m<CR>
Where: n = Massbus Adapter controller number
c = Alpha controller identifier; i.e. adapter number RH1 = URB
d = Device controller number of the DR70 under test (0-7)
m = Word or byte transfer mode (W/B)
tr = Transfer request level (11/780 only)
br = Bus request level
- REQUIREMENTS
HARDWARE:
VAX-11/780 or VAX-11/750
MS780 with 128kb of memory or Comet equiv.
Console
RH780 or RH750 Massbus Adapter
DR70 (M8440 or M8434)
BC08R Test Cable
The UUT must be disconnected from the user device by
removal of the cables and the test cable (BC08R) must
be connected from J1 to J2.
SOFTWARE:
VAX Diagnostic Supervisor (minimum, Version 6.8)
- SECTIONS
The EVDFM-1.0 program contains the following sections:
SECTION NAME MNEMONIC
------------ --------
Default None
Converational C[ONVERSATIONAL]
- DEFAULT
Default Test Section
The Default test section contains the tests necessary to verify the
functionality of the various logical parts of the device control
registers, and Massbus interface of the DR70. Any failures in this
section should be investigated with the Level 3 diagnostic (EVCGA-1.0).
The loop-back cable must be in place on the 8432 test module for these
tests.
- CONVERSATIONAL
Conversational Test Section
The Conversational test section contains a single test which allows the
operator to specify the parameters for a data transfer. This can be
useful for diagnosing data and parity logic errors, for DR70 repair.
Careful selection of the data to be transferred can provide useful
information about the functionality of the data tranfer, parity
generation, and parity checking logic.
