SSI Interface 5 - 9
Host RTS Line State
Parameter # 9Ah
This parameter sets the expected idle state of the Serial Host RTS line.
The SSI Interface is used with host applications which also implement the SSI protocol. However, you can also use
the digital imager scanner in a "scan-and-transmit" mode to communicate with any standard serial communication
software on a host PC (see Decode Data Packet Format on page 5-9). If transmission errors occur in this mode,
the host PC may be asserting hardware handshaking lines which interfere with the SSI protocol. Scan the Host:
RTS High bar code to address this problem.
Decode Data Packet Format
Parameter # EEh
This parameter selects whether to transmit decoded data in raw format (unpacketed), or with the packet format
defined by the serial protocol.
Selecting the raw format disables ACK/NAK handshaking for decode data.
