Break Sequence A series of one to ten characters users can enter on the command line interface to
send a break signal to the external device. A suggested value is Esc+B (escape
key, then uppercase “B” performed quickly but not simultaneously). You would
specify this value as \x1bB, which is hexadecimal (\x) character 27 (1B) followed
by a B.
See Key Sequences on page 231 for notes on key sequence precedence and
behavior.
View Port Log Seq The key sequence used to view the Port Log while in Connect Direct mode. Non-
printing characters can be specified by giving their hexadecimal code (see Break
Sequence above). The default is Esc+V (\x1bV).
See Key Sequences on page 231 for notes on key sequence precedence and
behavior.
View Port Log Select to allow the user to enter the View Port Log Sequence to view the Port Log
during Connect Direct mode. The default is disabled.
Zero Port Counters Resets all of the numerical values in the Port Counters table at the bottom of the
page to zero (0).
Logging & Events Click the Settings link to configure file logging (see Device Ports - Logging and
Events on page 204), email logging, local logging, and USB logging.
Power Management Click the Settings link to configure power supplies for the device connected to this
device port on the Device Ports - Power Management page.
Connected to The type of device connected to the device port. Currently, the EMG unit supports
Remote Power Managers (PDUs and UPSes) from 140+ vendors, as well as
Sensorsoft devices. If the connected device is an RPM, the user can assign an
RPM to the device port by either select an existing RPM (via the Select dropdown)
or clicking the Add RPM link to configure a new RPM for the EMG. If an RPM is
already assigned to the device port, the user can click on the Selected RPM link to
view status and configuration for the RPM. If the connected device is a Sensorsoft
device, the user can click on Device Commands to manage the Sensorsoft
device. If the type of device connected to the device port is not listed, select
Undefined.
Note: Sensorsoft temperature/humidity devices are supported with USB-to-serial
adapters (ftdi/pl2303/cp210x) but are not supported for use with USB-to-Serial
CDC_ACM devices.
Telnet In Enables access to this port through Telnet. Disabled by default.
SSH In Enables access to this port through SSH. Disabled by default.
TCP in Enables access to this port through a raw TCP connection. Disabled by default:
Note: When using raw TCP connections to transmit binary data, or where the
break command (escape sequence) is not required, set the Break Sequence of
the respective device port to null (clear it).
Port Automatically assigned Telnet, SSH, and TCP port numbers. You may override
this value, if desired. The value must be unique on the EMG; for example, you
cannot have two or more ports numbered 10001.
Authentication If selected, the EMG unit requires user authentication before granting access to
the port. Authenticate is selected by default for Telnet in and SSH in, but not for
TCP in.
Telnet/SSH/TCP
Timeout
Select the checkbox to cause an idle Telnet, SSH or TCP connection to
disconnect after a specified number of seconds as defined in the Seconds field to
the right.
