CABLES, CONNECTORS, AND TEST POINTS - Figure 1
This section will aid in locating cables, connectors, and
test points in the IBM Displaywriter work station. Wire
termination points are also given for doing continuity
checks.
Use the Point To Point Wiring Locator Chart (Figure 11)
for tracing wires and voltages through the Displaywriter
System.
When instructed by MAPs to measure a voltage:
Refer to the Locator Chart (Figure 1) to find the
name of the card or connector to be measured. The
cards and connectors are listed by module.
Refer to the figure number in the "Go To Figure"
column for the location of the connector or card
test point to be measured.
Signal Ground is to be used when measuring voltages.
Frame Ground is earth ground and is used only for elec·
trostatic discharge grounding. The use of frame ground
when measuring voltages should only be used when
instructed by MAPs.
Warning: Only use a Fluke* digital multimeter or it's
equivalent for all voltage readings while servicing the IBM
Displaywriter System. The use of any other multi meter
to check voltages may cause circuit damage.

Note: Figures 9, 9A, and 9B are the AC voltage ground-
ing path schematics. These figures also show the physical
locations of the AC grounds.
