RS232
The RS232 input characteristics of the MS860 can be modified accord- ing to the following nine parameters:
Baud Rate
Baud Rate (bits per second) refers to the speed of the data from the MS860. Normally, the baud rate of the host RS232 port should match that of the input device.
Default is “9600 Baud”.
Parity
Parity is an archaic technique used to detect data transmission errors by adding an extra bit to each character. This scheme has been sup- planted in modern communication devices by “Error Correction”. Default (and the current universal standard) is “No Parity”.
Data Bit
Data bit refers to the number of bits per byte that are dedicated to data (minus start/stop bits).
Default (and the current universal standard) is “8 Data Bits”.
Handshaking
Handshaking is the mechanism that controls the speed of data flow so that a slower receiver of data is not overwhelmed by a faster sender of data. Selections are:
Ignore
RTS (request to send) Enabled at Power Up
RTS Enabled in Communication Default is “Ignore”.
ACK/NAK
Data characters that are sent from the receiver to the sender in order to “acknowlege” or “not acknowlege” the receipt of the data without error. Rarely used these days.
Default (and the current universal standard) is “No”.
