Series 9000E Scanner/Decoder

4-8

Pin 4 NO COMPARE - User-programmable TTL level output pulse for

each code read that does not compare with a compare buffer

entry (open collector on some models).

Pin 5 DO NOT MAKE ANY CONNECTION TO THIS PIN.

RESERVED.

Pin 6 +12 VDC INPUT/OUTPUT - Alternate input power connection to

the Series 9000E Scanner/Decoder. +12 VDC + 5% @ 300 mA.

required. +12 VDC available at this pin when power connector

is used.

Pin 7,8 COMMON GROUND - Ground connection common to all

signals.

Pin 9 GOOD READ - User-programmable TTL level output pulse for

each code read by the Series 9000E Scanner/Decoder. (Open

collector on some models).

Pin 10 NO READ - User-programmable TTL level output pulse for each

code not successfully decoded. (Open collector on some

models).

Pin 11 COMMON GROUND - Ground connection common to all

signals.

Pin 12 DIGITAL OUTPUT - TTL level output. Bar = 1 Space = 0.

Refer to Section 2, Figure 2-1.

Pin 13 GATE INPUT - Input signal to the Series 9000E

Scanner/Decoder indicating that a code is present. Can be

supplied by a switch, a photoelectric sensor, or an input voltage.

The input voltage at this terminal is 30 VDC maximum.

Connecting this terminal to ground or applying a voltage less

than 0.8 V gates the scanner. See Figure 4-1.

Pin 14 PUSH BUTTON COMPARE - Shorting between this terminal

and ground will enter the next code read into the compare

buffer. Scanner will automatically be set to compare mode

when push button is used.
