The relative parameters of the main serial interface (baud rate, data bits, etc.)
are selected via software either using the WinHost utility program or Host
Mode programming. For more details refer to the section "Main Interface Menu"
in the WinHost Help On Line.
Details regarding the connections and use of the main interface selection are given in
the next paragraphs.
RS232 Interface
The serial interface is used in this case for point-to-point connections; it handles
communication with the host computer and allows both transmission of code data
and the configuration of the decoder. This is the default interface.
The following pins of the spring clamp connector are used for RS232 interface
connection:
Pin Name Function
18, 21 TX232 RS232 transmitted data
24 RX232 RS232 received data
19, 22 RTS232 RS232 request to send
25 CTS232 RS232 clear to send
26 SGND RS232 signal ground
It is always advisable to use shielded cables. The maximum overall cable length
must be less than 15 m (49.2 ft).
