Zebra DS8178 Product Reference Guide

SSI Interface 8 - 15
Software Handshaking
Parameter # 159 (SSI # 9Fh)
This parameter offers control of data transmission in addition to the control hardware handshaking offers.
Hardware handshaking is always enabled; you cannot disable it.
• Disable ACK/NAK Handshaking: When this option is selected, the digital scanner neither generates nor
expects ACK/NAK handshaking packets.
• Enable ACK/NAK Handshaking: When this option is selected, after transmitting data, the digital scanner
expects either an ACK or NAK response from the host. The digital scanner also ACKs or NAKs messages
from the host.
The digital scanner waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK.
If the digital scanner does not get a response in this time, it resends its data up to two times before discarding
the data and declaring a transmit error.
