ACK/NAK Handshaking
If you enable ACK/NAK handshaking, all packeted messages must have a CMD_ACK or CMD_NAK
response, unless the command description states otherwise. This parameter is enabled by default. Zebra
recommends leaving this handshaking enabled to provide feedback to the host. Raw decode data and
WAKEUP do not use ACK/NAK handshaking since they are not packeted data.
Following is an example of a problem which can occur if you disable ACK/NAK handshaking:
• The host sends a PARAM_SEND message to the digital scanner to change the baud rate from 9600
to 19200.
• The digital scanner cannot interpret the message.
• The digital scanner does not implement the change the host requested.
• The host assumes that the parameter change occurred and acts accordingly.
• Communication is lost because the change did not occur on both sides.
If you enable ACK/NAK handshaking, the following occurs:
• The host sends a PARAM_SEND message.
• The digital scanner cannot interpret the message.
• The digital scanner CMD_NAKs the message.
• The host resends the message.
• The digital scanner receives the message successfully, responds with CMD_ACK, and implements
parameter changes.
