The Point to Point Wiring Locator Chart (Figure 11) will
aid service personnel locate connector wires when doing
continuity checks, tracing wires in cables, and checking
voltages.
The connectors and cards are listed by module. Printer
Sharing cables and connectors are listed separately.
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 multimeter
to check voltages may cause circuit damage.
