Overview
The Contemporary Research IP-HTDV is an HD tuner that offers analog and digital tuning, a variety of HD
and NTSC output options, and full systems integration via Ethernet, RS-232, or discrete IR control.
The IP-HDTV tuner is capable of receiving analog and unscrambled digital programming, either off-air or
CATV. High-definition and up-scaled NTSC video can be viewed from the tuner's component, RGB, or DVI
ports, in 1080i, 720p, 480p or 480i formats. Standard 480i video can be recorded or monitored from
composite and S-Video outputs. Stereo, mono, and Dolby 5.1 surround sound is available from optical, coax,
and two stereo analog audio channels. Closed captioning is provided in both analog and digital formats.
Full control can be integrated from Ethernet, RS-232, IR, and wired IR control ports. System setup can be
performed from a control system, front-panel controls, and on-screen menus from the included IR wireless
remote. In addition, the tuner can install on a shelf or rack-mounted with an optional rack kit.
Applications include HD and SD TV tuning for conference and meeting rooms, board rooms, and home
theaters.

Analog and Digital Tuning
One of the biggest paradigm shifts in digital TV is how channels are accessed. Gone is the familiar Channel
33. Now you have 33-0, 33-1, 33-2, and so on. In a nutshell, the new tuning options are:
•
•
Analog Channels. Entering the number-0 accesses the traditional analog TV channel.
Digital Channels. Entering the same channel-1 tunes the digital equivalent of the analog channel.
Note that the digital channel is broadcast on a UHF frequency. Digital tuners see the channel ID (NN-
1) in the signal and lists by that name instead of the actual frequency. This way, the broadcasters
keep their channel identity, even when analog goes away.
•
•
Multicast Digital Channels. Because digital is more compressed than analog, broadcasters are
often including additional sub-channels, listed as NN-2, NN-3; up to 6 if the station is only
broadcasting SD quality programming.
Two-Digit Tuning. If you are currently watching a digital channel, entering the old channel format,
such as 33, will access 33-1. If you are watching an analog channel, entering 33 will take you to 33-
0.

Ethernet Setup
Ethernet Connection
The IP-HDTV typically communicates over a network using a static IP address, and is shipped set to a default
address:
IP Address: 192.168.1.231
Subnet Mask: 255.255.255.0
Gateway Address: 000.000.000.000
Local Port set to 23 (Telnet standard)
Odds are, at least the IP address will change when the IP-HDTV is connected to the client’s network. One
your first steps will be to obtain a static address from the client’s IT department, as well as an external
gateway IP address if you intend on supporting the system from your office or anywhere outside the site’s
firewall.
Once you change the settings, create a label noting the settings and attach to the back of the IP-HDTV.
Reset IP Address
Since its possible another network device is using the default IP address, the best approach is to enter the
new settings offline, outside the network. You can use one of two, requiring one of two offline options:
1. Direct PC Connection. Use an Ethernet “Crossover” cable to make a direct connection to the IP-HDTV
Ethernet port and your PC. Two pairs of wires are reversed at one end to create a direct
send/receive path for data.
2. Hub or Switch Connection. Another approach for connection is to use a standard Ethernet hub or
switch between your computer and the IP-HDTV. Using standard Cat5 Ethernet cables, connect your
PC to one port, and then connect the IP-HDTV to the second port.
RS-232 and Telnet Terminal Communication
You can communicate with the IP-HDTV with HyperTerminal using an RS-232 or TCP/IP connection to Port
23.

Ethernet and RS-232 Control Protocol
Overview
The IP-HDTV full duplex Ethernet/RS-232 scheme enables a system programmer to control all TV Tuner
functions as well as monitor 3 groups of TV Tuner status. All commands are sent as ASCII strings. No delays
between characters or commands are required, as data is interrupt driven and buffered.
The 3 status groups are: Channel/Source Select, Audio Levels/Mode and Front Panel. The Mute A/V button-
function status from the IP-HDTV front panel has been grouped with the Channel/Source for simplicity in the
most common modes of operation. Each of the groups has one ASCII status response string containing all of
the status data for that group. The current status string of a group is sent from the IP-HDTV whenever a
valid command for that group is received by the IP-HDTV RS-232 port or front panel. A group's status may
be requested at any time via the RS-232 port. Status of all 3 groups is sent at power up. The format of each
group's status response string remains the same always.
Up to 9 IP-HDTV units may be cabled together and addressed for individual control from a single RS-232
port. Each IP-HDTV is assigned a unique unit code.
Communications parameters (Front Panel Mode 1) are 300 to 9600 baud, 8 data bits, No parity, and 1 stop
bit. Factory default is 9600 baud, Unit#1.
All settings are saved to NVRAM in the IP-HDTV.
The tuner will accept non-standard RS-232 control such as voltage that swings from 0 to +5 VDC, commonly
found when IR ports are used to send RS-232 commands.
General protocol specifications
Characters in command strings to the IP-HDTV are common ASCII keyboard characters.
Command strings sent to the IP-HDTV begin with the ASCII > (greater than symbol) as an 'Attention'
character and end with carriage return - ASCII CR, Hex $0D, or keyboard Enter - as an 'End-of-command'
character.
Responses from the IP-HDTV begin with the ASCII < (less than symbol) as an 'Attention' character and end
with a carriage return followed by line feed an ASCII LF or Hex $0A as 'End-of-command' characters.
A carriage return is required at the end of each command and is assumed in all examples.
Command String Structure
[Attention] (Unit#) [Command] (Parameters) [Return]
Attention
Unit#
Single character (>) starts the string
The Unit# is expressed as an ASCII 0-9 when used in multiple tuner applications.
To address all units, use a Unit # of 0 (Zero)
No unit number will default to Unit#1
A two-character command
Added attributes to some commands
A carriage return ends the command string, you may use ASCII CR, Hex $0D, or keyboard
‘Enter’ in programming. For simplicity, the programming examples in the manual will not

IP Control Options
RS-232 Display Control
An IP-HDTV that is controlled over Ethernet can also offer a pathway for IP-driven RS-232 control to a
display or projector. This application takes advantage of the fact that multiple Telnet ports can communicate
over the same TCP connection.
•
•
•
•
Set the control system to communicate with the IP-HDTV over Ethernet through Telnet Port 23, or a
different Telnet port you’ve defined in the IP-HDTV for control.
Set the control system to control the display over Ethernet using Telnet Port 2001, same IP address
as the IP-HDTV.
The IP-HDTV will pass data to and from the Telnet port 2001 through the RS-232 control port on the
back. This connection offers full bi-directional control of the display.
The RS-232 baud rate can be changed via front-panel settings or programming, presently fixed at 8
data bits, no parity, one stop bit.
TCP and UDP Connectivity
The IP-HDTV can be controlled via TCP or UDP protocols. In most cases, a control system Ethernet port will
be set to connect using TCP/IP, which provides direct, two-way communication between the tuner and the
control system.
System programmers could opt to use UDP protocol instead, which is useful for simple, one-way control or
broadcasting control commands to all IP-HDTV tuners on the LAN. The tuners can send status information
back via UDP, but system programming will need to read the strings to interpret which IP address is sending
the data. Check with CR Support for more information on this option. The IP-HDTV can communicate over
both UDP and TCP protocols, no special settings or programming is required.
Web Control Page
The IP-HDTV features on onboard Web page for remote IP control of the tuner,
accessed by entering the IP address of the tuner in a standard Web browser.
Simply click on the Web panel buttons to control the tuner, and the text area at
the top will provide system feedback.

RS-232 wiring for control or programming should only use pins 2, 3, 5. Cables with all pins wired can lock
out front-panel programming and data communication (Pins 4 and 9 are inputs).
Multiple Tuners
Up to nine tuners can be daisy-chained from one RS-232 control port. Remember that you will need to use
the Unit# address in your programming when you control more than one tuner from the same control port.
Set the first unit in the RS-232 chain to the highest Unit#, then wire in sequence to the last tuner in the
chain. The reason for this is that CR tuners use an intelligent data bus - the highest number tuner receives
all commands, and then passes on commands addressed to tuners with lower unit numbers. The next tuner
in the chain does the same, and so on until the last unit.
