The C2N-DAP8RC also provides 12 video sensors, plus one SENS input for 
connection of an external current sensor. The <Sense_In> outputs will go high 
whenever the sensor detects the presence of a video signal on RCA inputs 5 through 
16. 
The <SENS> input is a TTL input with pull-up resistor, designed to sense a contact 
closure. 
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 55.) 
The symbol, shown below, is only used when the C2N-DAP8RC 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 and on the next page 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-DAP8RC RS-232 port when 
the state of the RTS line is set. 
str1  The C2N-DAP8RC RS-232 port is capable of receiving complex serial data 
in the form of serial data strings on this input line.
