Mode 3 – Normal

Mode 3 is the normal operating mode. You can program the scanner to add PACESETTER Plus information to the decoded UPC/EAN data that is sent to the host terminal. Perform the following procedure to enable or disable PACESETTER Plus information.

1.Scan the Programming Mode tag (must be first tag scanned after power-up).

2.Scan the Hex 3 tag.

3.Scan the Hex 1 tag.

4.Scan the Hex 3 tag.

5.Scan the Hex 1 tag to disable PACESETTER Plus information, or the Hex 2 tag to enable PACESETTER Plus information.

6.Scan the Save and Reset tag.

The PACESETTER Plus information describes the label readability much the same way as described in Mode 2. However, the host software must be capable of receiving the extra data being sent to it.

With OCIA and RS-232 communications, PACESETTER Plus information is sent as trailer information. With IBM communications, PACESETTER Plus information is sent as header information that is located between the last Status byte and the first tag data byte in the message. The PACESETTER Plus format is defined as the normal UPC/EAN format with the following added.

OCIA	RS-232	IBM
OCH, xyH, xzH	43H, 3yH, 3zH	OCH, 0yH, 0zH

x = High nibble containing character parity depending on communication format (or 0).
