device that provides dry contact closure (no voltage) attaches to the two-pin port
(labeled SENS). The monitor plugs into the CNXRMCS. The symbol for this port,
shown after this paragraph, consists of a single output. When this <
Current Sense>
output is high, the monitor plugged into the CNXRMCS is on. A low output
indicates that the monitor is off. This signal can be used as a feedback indicator
when connected to the user interface (i.e., touchpanel).

Slot 4: 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 “Firmware
Upgrade” on page 29.)
The symbol shown following this paragraph is only used when the CNX-RMCLV
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. Inputs and outputs
surrounded by brackets ([…]) are optional.

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 CNXRMCLV RS-232 port
when the state of the RTS line is set.
str1
The CNXRMCLV RS-232 port is capable of receiving complex serial
data in the form of serial data strings on this input line.
