3.10 ES210 Bridge Serial Port Settings
The serial port on the front panel of the ES210 Bridge is
configured by default to be used for
Console port access to the
Bridge CLI, as other Bridge model serial ports are used.
On the ES210 Bridge, you can reconfigure the serial port to
instead connect the Bridge to an external third-party
Serial
Sensor
, or another serial device.
When
Serial Sensor Settings are Enabled, the serial port
behaves like a serial terminal server, passing data between the
specified TCP (Transmission Control Protocol) port and the
device connected to the serial port. Serial data can be
accessed using
telnet ip_addr tcp_port, with no options.
Only one TCP connection at a time is permitted to the
Serial
Sensor
TCP port. The ES210 Bridge can send data from and to
the connected serial device over any of the Bridge’s wired or
wireless interfaces, under the security provisions configured for
the interface and on the Bridge overall.
3.10.1 Configuring the Serial Port
NOTE: You must
reboot the Bridge
in order to change the
function of the ES210
Bridge serial port.
Enabling Serial Sensor Settings disables the serial port for
Bridge CLI access. The Bridge CLI remains accessible by a
terminal emulation application over an SSH2 (Secure Shell 2)
network connection, provided
SSH Access is Enabled (the
default; refer to Section 4.1.6).
Disabling the
Serial Sensor function re-enables the port’s
Bridge CLI
Console function and automatically returns serial
port settings to the correct values for the Bridge CLI (baud rate:
9600, parity: none, stop bits: 1).

Serial Sensor Settings
frame, ES210
Use Serial Sensor Settings to enable and configure the ES210
Bridge’s serial port to connect to an external serial device.
Admin. State - determines whether the port’s Serial Sensor
function and the rest of the configuration settings in the
Serial Sensor Settings frame are Enabled or Disabled (the
default). You must reboot the ES210 Bridge in order to
change
Admin. State, as directed below.
Port - specifies the TCP port for the serial interface. Port
values between
5000 and 65534 are valid; the default is
port
5001.
Baud Rate - specifies the number of bits per second for the
serial connection at
300, 1200, 2400, 4800, 9600 (the
