VIDEO SOURCE VALUE
CAT5 1d – 4d
RCA 5d – 16d
No Source 0d
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.
