Parameter Menus 10 - 95
Software Handshaking
Parameter # 9Fh
This parameter offers control of the data transmission process in addition to that offered by hardware handshaking.
Hardware handshaking is always enabled and cannot be disabled by the user.
Disable ACK/NAK Handshaking
When this option is selected, the decoder neither generates nor expects ACK/NAK handshaking packets.
Disable ACK/NAK
(00h)
Enable ACK/NAK Handshaking
When this option is selected, after transmitting data, the scanner expects either an ACK or NAK response from the
host. The scanner also ACKs or NAKs messages from the host.
The scanner waits up to the programmable Host Serial Response Time-out to receive an ACK or NAK. If the
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.
*Enable ACK/NAK
(01h)
