Multipacket Option

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 scanner sends data packets continuously, without using ACK/NAK handshaking to pace the transmission. If overrun, the host 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 - It operates like Option 2 but adds a programmable interpacket delay. See Interpacket Delay to set this delay.
