. The C2N-
DAP8 slots, sub-slots, and corresponding symbols are described in the following
paragraphs. Because of their complexity, the description of the symbols for the
Surround Sound Decoder symbol, Slot 08; the Speaker Settings symbol, Slot 09 Sub-
Slot 1; the Full Parametric EQ Controls symbol, Slot 09 Sub-Slot 2; and the Graphic
EQ Controls symbol, Slot 09 Sub-Slot 3, are described in the Appendix “Advanced
Programming Symbols,” beginning on page 52, for those advanced programmers
who wish to program them in SIMPL Windows.
Slot 04: Built-in RS-232 Port
This port serves two purposes: an RS-232 port for two-way communication with
serial devices, and a console port for upgrading firmware. (Refer to “Uploading and
Upgrading” on page 45.)
The symbol, shown below, is only used when the C2N-DAP8 communicates with a
serial device. The bidirectional port supports baud rates up to 115K baud N81 and
has RTS/CTS handshake signals. The tables below list the inputs/outputs and their
functional description. Input and outputs enclosed by brackets ([…]) are optional.

Built-in RS-232 Symbol Input Descriptions
INPUT(S) FUNCTION(S)
[tx$]
More advanced signal processing can be done through serial strings and
the tx$ input line on the symbol.
[enable]
If signal is present on this input, it must be high to permit activity of the
symbol. If the signal is low, the symbol is disabled.
[break]
Some devices use a break character before sending out any serial data.
Break characters are sent out the port separated pace parameter.
[rts]
RTS is an output from the program to the C2N-DAP8 RS-232 port when the
state of the RTS line is set.
str1
The C2N-DAP8 RS-232 port is capable of receiving complex serial data in
the form of serial data strings on this input line.
Built-in RS-232 Symbol Output Descriptions
OUTPUT(S)
FUNCTION(S)
[rx$]
More advanced signal processing can be done through serial strings and
the rx$ output line on the symbol.
[cts]
CTS is an input to the program that monitors the “Clear to Send” line status
of the C2N-DAP8 RS-232 port.
str2
The C2N-DAP8 RS-232 port is capable of sending complex serial data in
the form of serial data strings on this output line.
