malfunctioning. The “Making Connection” chapter
has information on display codes that are used by
some systems.
A format can be programmed to check these lines
and report the results to the operator.
The DCBM parameter determines which of up to 4
sense lines will be tested. A value of 15 will test all
4 lines. A value of 7 will test 3.
The DCEX parameter is the display code number
that you are expecting to get back from a particular
display. The actual value that is read back is shown
in the “Format” test image.
❖ The 801G* does not use the display code data to
change its own operating modes. The DCBM and
DCEX parameters are only used to provide in-
formation to the operator so that they may com-
pare the expected and actual results.
Outputs Control
The last set of format parameters allow you to de-
termine which outputs are active when the operator
first selects the format from memory.
❖ In the current version of firmware, the status of
the “Outputs” button has priority over individual
gating controls. Selecting a format while the
outputs are turned off will keep all of the out-
puts off until the button is pressed. Selecting a
format while the outputs are turned on will ac-
tivate all of the outputs that have been gated on
in the format.
