Figure A-4 Host Connector Default Pins - Microscan MS-3000 User Manual

Shorting Pins 7 and 11
If a profile card is not accessible, it is necessary to default the decoder by
shorting pins 7 and 11.
Caution: Be certain that the correct pins are shorted. Shorting the wrong
pins can cause serious damage to the unit.
Procedure:
1. Turn power to the decoder ON.
2. Locate pins 7 and 11 on the host connector
a pen.
(Use a small length of light wire approx. 4 inches, 18 to 26 gauge for
shorting.)
3. Momentarily short pins 11 and 7. Listen for a series of short beeps.
Within 3 seconds, short pins 11 and 7 again. A longer beep should be
heard. If not, repeat the process.
Note: Using switching
power supplies as a power
source is not recom-
mended due to excessive
ripple characteristics.
