SSI Interface 8 - 13

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 use

the imager 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 8-13

). 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.
