3.5.3 The LCD-9151-201-x utilizes three (3) connectors. P1 is a 13-pin
connector that provides power input, ground, video input, monitor
on/off control and monitor status.
The monitor on/off function (P1, Pin 5) is transition level sensitive.
Either a constant ground input or momentary ground input may be
used. If constant ground input is used, the monitor will activate to
the ON state when +28 VDC power is applied to Pin 1 and a
constant ground is on Pin 5. If no constant ground is present, then
this input will float to a high level causing the monitor to be in the
OFF state.
If momentary ground input is used, the monitor will alternate
between ON and OFF states with each momentary ground pulse of
duration between 50 and 250 msec. If momentary ground logic is
used, then the monitor will power up to an OFF state when power is
applied to Pin 1.
3.5.4 P2 is a 9-pin connector that provides power output to the SP-LCD6,
ground, and data bus control. Three (3) ID pins are also provided

4.3 General Troubleshooting Procedures
•Verify power to the unit by rechecking +28 VDC power is applied to the
proper pins on the unit. Use a voltmeter to verify correct level.
•Remove power from the unit for at least one (1) minute and reapply
power.
•Recheck all connections to the unit for security. Check all harness
runs for possible pinching. Recheck all pinouts for application
accuracy.
•Check data bus integrity by utilizing a voltmeter, oscilloscope, or other
voltage instrument to verify proper input voltage on the data bus pins.
Typical measurements are as follows:
A to Ground: 4.0 to 4.5 VDC
B to Ground: 0.1 to 1.0 VDC
If any device is transmitting (i.e., holding bus active), then these typical
measurements would be reversed for the A-to-Ground and B-to-
Ground. This troubleshooting tool can help indicate a data bus lockup.
If this occurs, remove the data bus from all other equipment one piece
at a time. As each is removed, check the bus status to see if it is now
functioning properly. Once you have removed the piece or pieces of
offending equipment, disconnect power and then reconnect everything
but the suspect component. Reapply power and then test the
functionality of the unit(s).
