Transmit SV Commands
This button invokes a special screen where up to fourteen individual commands may be composed and transmitted in any order. Proper use requires knowledge of the SV download language. See the Chapter 6, SV Download Language for details. This function is intended for advanced setup involving special functions not normally accessed by ScanView. These can include special transmission formats, special commands in a custom SV firmware version or diagnostic functions used by Hand Held Products’ Application Support and Service personnel. The shortcut key for this function is F4.

Reports a new analysis of any bar code(s) currently in the SV

Session Mode Notes
ScanView updates the bar code analysis graphs each time a bar code is processed by the verifier; but there is a limit to the graph update rate that ScanView can sustain. Factors that determine the processing load include the bar code analysis rate (bar codes per second) and the number of displayed analysis parameter graphs (selected by the user). The Windows communications facility has a data buffer that allows the graph processing to ‘catch up’ between bursts of transmitted data. If the incoming data volume
