Problems and Solutions

Problem Possible Solutions
A)
The Scanner is not
operating at all. 1. Press the Display Wakeup button to turn on the display.
2. Plug the console port cable into the local console port, and run ScanWin on your
Laptop to communicate to the Scanner 1141.
3. Check battery voltage on the Scanner 1141’s main battery located in the rear of
the enclosure. The battery voltage must be:
•
above 6 VDC for 6-volt systems
•
above 11.2 VDC for 12-volt systems
4. If a Class I, Division 2 integral charge controller is used, check the Batt+ and Batt-
terminals (terminals 4 and 5) on the main board and make sure the connections
are secure. A power cable should be connected to the Power +/- terminals
(terminals 2 and 3) on the main board.
5. Perform a restart by setting the Pwr switch SW9 to the OFF position, and then
turning it ON again. Within 1 minute, the Scanner 1141 should display the
message “Power on restart”.
6. If Scanner is still not operating, set the Pwr switch SW9 to the OFF position.
Disconnect the Power+ and terminals for 30 seconds, ensuring that the
ends of the disconnected wires do not contact anything. Set Pwr switch SW9 to
the ON position. Within 1 minute, the Scanner 1141 should display the message
“Power on restart”.
B)
The Scanner
display will not
“power up”.
1. Press the Display Wakeup button.
2. Adjust the “Contrast” potentiometer in the upper left part of the mainboard. With a
small slotted screwdriver, rotate the control clockwise to increase the contrast to
the point where all of the display pixels are blackened out. If this works, turn the
contrast back to the desired setting.
3. See problem A: “The Scanner does not seem to be operating at all.”
C)
The Scanner will
not talk to ScanWin. 1. Ensure that the console port cable is plugged into the Scanner 1141, and the
correct COM Port is displayed on your laptop.
2. Check communications settings to ensure that they match those of the Scanner
1141. If you are unsure of the Scanner’s settings, turn the Pwr switch SW9 off and
then on again. When the Scanner 1141 boots up, the display will reveal the
firmware version (e.g. NFlo M4.3.3G) followed by the local console port settings
(e.g. 9600, 8, N, 1). In the example given, assuming the console port cable is
plugged into COM Port 1 of the PC, the default values for communication are as
follows:
ScanWin is used for version 4 firmware (e.g. NFlo M4.3.3G). Local console
communication settings are found in the main menu Tools>Communication setup.
Family and Scanner name are _DIRECT_, with default settings as follows:
•
Port group is DIRECT.
•
Baud rate is 9600.
•
Stop bits is 1.
•
Parity is none.
