Character Frame Control is used to adjust timing gap between bytes within one character data output by C70.
Intermessage Delay is a time delay between messages output by C70. Increasing this delay will help host
applications process the incoming data on time.
Intercharacter Delay is a time delay between data characters output by C70. These two parameters are used to
synchronize data communication when : 1) the data transmission speed is too fast, characters may be skipped; 2)
multitasking operation system or host computers in a network may slow down the keyboard handling; 3) various
notebook or desktop PC systems require different timing parameter settings. Please always add one extra unit as safty
margin when adjusting these two parameters.
Interfunction Delay is a time delay between the transmission of each segment of the message string.
