Cts Always True - Brainboxes ES Series Product Manual

The serial port settings of the ES device are stored in the firmware of the device. As a result of this
they have to be configured through the web configuration pages. Click the "Configure Settings" button
and you'll be taken to the serial port webpage where the port settings can be configured.
Port Status: Displays current state of the port, that is, whether the port is open (Connected)
or closed (Idle). When the port is connected, the IP address and TCP port the device is
connected to is displayed.
Port Type: The Port Type drop down box allows you to set the serial port to RS-232 mode or
RS-422/485 mode. For information about the pin outs when the port is set to RS-232 or RS-
422/485 mode see Section 3, Hardware Features. For information about the RS-422/485
configuration see the section below, RS-422/485 Settings.
Always use these settings: If this checkbox is ticked, the port will communicate using the
baud rate, data bits, parity, stop bits and flow control set in this section regardless of what
settings the application is using. For example, this will allow you to force baud rates that your
application does not allow you to select. This can be useful for interfacing to equipment which
uses higher baud rates or unusual baud rates which your application does not support.
Protocol Settings
Protocol Type – Raw TCP: Data sent over the network is the same as the data sent
o
over the serial link.
Protocol Type – Telnet: Data is sent over the Transmission Control Protocol using a
o
virtual terminal connection.
Local TCP Port: Configures which TCP port the ES device will use.
Connection Timeout: This is set to "0" by default. If the Connection Timeout is set to
anything other than 0, the connection to the port will be disconnected automatically after
being idle (i.e. no data is being received or sent to and from the port) for the specified time.
The LED for the port will go off at this point. If the Connection Timeout setting is "0", the port
will need to be disconnected manually by the user.

CTS Always True

CTS Always true is only relevant when the ES device is configured to operate in RS-232 mode and
when RTS/CTS flow control is enabled.
NB: When the ES device is set to RS-422/485 mode, the RTS/CTS handshaking is not supported. As
a result, "CTS Always true" will be enabled by default.
