SSI Interface 4 - 9

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 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

scanner transmissions. At the end of transmission, the digital 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.
