The symbol shown following this paragraph is only used when the CNXRMC
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. Inputs and outputs surrounded by
brackets ([…]) are optional.
Two-Way Serial Driver Symbol
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 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 by the
specified pace parameter.
[rts]
RTS is an output from the program to the CNXRMC RS-232 port
when the state of the RTS line is set.
str1
The CNXRMC 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 CNXRMC RS-232 port.
str2
The CNXRMC RS-232 port is capable of sending complex serial data
in the form of serial data strings on this output line.
NOTE:
When present, the delimiter is appended to every string of text in the port
definition (both transmitted and received strings).
Slot 6: Video Output Control
The CNXRMC’s built-in Video Output Control module allows the programmer to
disable and thus control the seven ports, VIDEO OUT (A – G), via the SIMPL
Windows program. The symbol for this module is shown on the next page. The ports
on the CNXRMC are by default enabled (refer to the signal routing diagram on page
10 for details).
When the input is high, the port is disabled. These inputs can be driven by a user
interface.
