Multipacket Option
Parameter # 334
SSI # F0h 4Eh
Scan one of the following bar codes to control 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 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 scanner
transmissions. At the end of transmission, the scanner waits for a CMD_ACK or CMD_NAK.
• Multi-Packet Option 3 - This is the same as option 2 with the addition of a programmable interpacket delay.
See Interpacket Delay on page 8-21 to set this delay.
