Multipacket Option
Parameter # F0h, 4Eh
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.
