DIGITAL COMPUTER ASSEMBLY 1A11
7 - 3
INPUT CODE: CALCST
a. DESCRIPTION
This module gives the operator instructions to check extender assemblies 1A9A1,
1A9A2, 2A2A8, and the extender assembly in the AN/USM-410(V)2 for status of front
panel lights.
Then, the module exercises the calculate commands. If a time out
error does not occur before the first calculate command test is completed, the
IEEE 488 Bus, extender assemblies, and digital computer assembly 1A11 are
functioning normally.
Since a time out error “locks out” the self-test program, the
error message is displayed at the start of the first calculate command test.
A calculate error will cause a prompt to be displayed upon completion of the
test.
b. REPLACEMENT PROCEDURE REFERENCE
The following list provides a cross reference of replacement items to
replacement procedures.
The item column identifies the item to be replaced by
reference designation and part number.
The reference column identifies the
procedural paragraph used to perform the replacement action. The VDT screen will
display the proper sequence of repair/replace actions.
