6 - 12 Symbol DS6707 Digital Imager Scanner Product Reference Guide

This parameter controls ACK/NAK handshaking for multi-packet transmissions. 

• Multi-Packet Option 1: The host sends an ACK / NAK for each data packet during a multi-packet 

transmission. 

• Multi-Packet Option 2: The digital imager scanner sends data packets continuously, with no ACK/NAK 

handshaking to pace the transmission. The host, if overrun, can use hardware handshaking to temporarily 
delay digital imager scanner transmissions. At the end of transmission, the digital imager scanner waits for 
a CMD_ACK or CMD_NAK. 

• Multi-Packet Option 3: Option 3 is the same as option 2 with the addition of a programmable interpacket 

delay.
