SSI Interface
6 - 5
ACK/NAK Disabled and Packeted DECODE_DATA
In this example ACK/NAK does not occur even though
packeted_decode
is enabled because the ACK/NAK
handshaking parameter is disabled.
ACK/NAK Disabled and Unpacketed ASCII Data
Data captured by the decoder is sent to the host.
Communication Summary
RTS/CTS Lines
All communication must use RTS/CTS handshaking as described in the
Simple Serial Interface Programmer’s
Guide
, p/n 72-40451-xx. If hardware handshaking is disabled or bypassed, the WAKEUP command must be sent
prior to all other communications, or the first byte of a communication message may be lost during the decoder
wakeup sequence.
ACK/NAK Option
Enable or disable ACK/NAK handshaking. This handshaking is enabled by default and Motorola recommends
leaving it enabled. Disabling this handshaking can cause communication problems, as handshaking is the only
acknowledgment that a message was received, and if it was received correctly. ACK/NAK is not used with
unpacketed decode data regardless of whether or not it is enabled.
Number of Data Bits
All communication with the decoder must use 8-bit data.
