- HELP
EVDTD is a repair level (level 3) diagnostic, designed to test the
functionality of a FEP command bridge module (MASTER side.) The
program consists of thirty-three tests which provide error messages
identifying data, I/O, and function errors. The program runs with the
diagnostic supervisor from the system console in a stand-alone
environment.
- SECTIONS
All tests of this diagnostic are in one section. No quick verify
mode is provided since the diagnostic takes little time to execute.
Separate level 2 diagnostics are available.
- DEVICE
This diagnostic tests the FEP command bridge module (M8642). The
VAX CPU and UNIBUS Adaptor are assumed to be reliable. Either the
loopback cables or the link cables to the M8632 (LSI-bus) bridge
module or the M7484 (Unibus-bus) bridge module must be attached
before starting the tests. If the link cables are attached the
operator must answer 'No' to "IS LOOPBACK CABLE INSTALLED?" query.
- CSR
The default UNIBUS address is 764500, octal.
- BR
The option normally issues UNIBUS signal Bus Request at level 5.
- BRIDGE TYPE
The diagnostic tests both UNIBUS and LSI-bus FEP's. Configuration
input is required for consistancy with other diagnostics. Acceptable
values are U or Q. There is no default.
- ATTACH
The FEP exerciser must be loaded before it can be attached:
DS> LOAD EVDTD
Next, the device must be attached and selected. There are two ways
in which this can be done. The first way is by using the prompt
mode and the second way is the explicit (no prompt) mode.
Both the UNIBUS Adaptor and the FEP must be attached before the
diagnostic can start.
