Multipacket Option - Symbol DS4308 Product Reference Manual

Multipacket Option

Parameter # 334 (SSI # 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.
