read operation continues to fail after one second, or some other value is obtained, you should
assume the entire initialization process has failed.

Status Data Available from a DLAN Module

Three locations in VME dual-ported RAM contain one byte status codes. The locations and
values of these codes are shown in Table 2-3. Locations for additional status data are also
shown in the table. These items are explained in the following sections.

Module ID String

The eleven bytes of VME dual-ported memory starting at offset 13 hexadecimal should contain
these characters.

Note that the even bytes contain ASCII space characters.

Power-Up Diagnostics Result

The DLAN Module self-test routines that run when the module is powered on copy a NUL-ter-
minated string of ASCII characters to VME dual-ported RAM, starting at offset 0B2 hexadeci-
mal (178 decimal). The string is copied to contiguous (both odd and even) bytes. The normal
string value is

Diag Req 111 Completed(1)

; any other string indicates that an error oc-

curred during the tests. The nature of the error can be determined from the string. For exam-
ple:

Error Message String

ACC chksum is xxxx not yyyy

Checksum failure of EPROM at board
