NCast Presentation Recorder Reference Manual
Choose a password, which has random characters and numbers and is at least 8 characters in length.
Unfortunately, Telnet protocol sends this password in clear-text, so network sniffers may be able to
compromise this entry.
6.6.3. IP Restriction
This limits the valid IP addresses, which may send commands to the Presentation Recorder. Normally
this field should contain a single IP address, which is the IP of the controller in charge of the Presentation
Recorder. Thus, if the password is compromised an attacker will still not gain access to the unit. This
field may contain:
www.xxx.yyy.zzz
A single address
www.xxx.yyy.*
An address range
www.xxx.yyy.0/24
A subset of a network (CIDR notation)
www.xxx.yyy.zzz,sss.ttt.uuu.vvv
A comma-separated list of addresses
www.xxx.yyy.zzz,sss.ttt.uuu.*
A comma-separated list of addresses and ranges
Standard CIDR notation is documented in IETF RFC 4632.
6.6.4. Port
For security reasons the default Telnet port is not utilized. Enter a port number if the factory setting is not
acceptable.

6.7.1. Overview
The PR-HD Series Scheduler is a feature that allows the manager of one or more Presentation
Recorders to schedule these appliances through use of a Google calendar or through use of industry-
standard iCalendar files. The manager can start and stop each Presentation Recorder at a
predetermined time, load unique settings for each individual presentation, send serial control commands
to each Presentation Recorder to provide additional functionality, and specify how and where the
Presentation Recorder sends its output, all without touching the actual Presentation Recorder user
interface. All that is required is one or more Presentation Recorders, each with a connection to the
Internet, and access to a Google calendar or an iCalendar file, no matter where in the world the
equipment is located.
6.7.2. Components of the Solution
The Scheduler Implementation uses three components to allow automatic start/stop scheduling of one or
more Presentation Recorders in a network. These components are:
•
An administrative interface based on Google Calendar or other Calendar system using
iCalendar
•
A scheduler process which queries the calendar information and activates the Presentation
Recorder.
•
The Presentation Recorder IP serial command interface, which receives commands at the
scheduled times.
6.7.3. Scheduler Overview
The following sections describe how to use a Google Calendar account or an iCalendar file to setup a
schedule for one or more Presentation Recorders and how to use the Scheduler web page.
Complete documentation for the serial command set is in the “
Presentation Recorder Serial Interface
Specification
”. Please refer to this manual for a more complete description of commands which may be
used. This guide lists a few basic commands which allow the user to start and stop a unit from the
Scheduler interface.
6.7.4. Google Calendar Events
Google Calendar is a web-based interface used to enter calendar events such as meetings and
appointments. It allows multiple personal calendars (e.g. business and home) and allows sharing of
public and private calendars with friends and associates.
