6 - 8 DS6707 Digital Imager Scanner Product Reference Guide
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, the digital
imager scanner can be used 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 6-8 ). 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.
