IP-SDI 4i Product Manual 042020
Creating and Loading the Channel List
A list of available channels will need to be entered into the IP-SDI 4i in order to view the IPTV streams. Each channel entry will include
UDP/RTP, channel number, IP address and port, program number, and channel name. Each channel’s IP address can be that of a unicast or
multicast stream. The list can contain a mix of unicast and multicast addresses. An entry will need to be made for each program of a multiple
program transport stream.
In the case of a unicast stream, the IP address in the channel list will need to match the unicast address entered in the network menu of the
web page, front panel setup menu or by RS-232 command. The unicast address cannot be identical to the IP address of the unit.
A channel number is assigned to each IPTV stream and is used for identification. The channel number is used to recall a channel directly
either by the optional handheld remote, web page, or a command from a control system processor. One-part and two-part channel numbers
are supported. The valid range for one-part channel numbers is 1 to 9999, and the valid range for two-part channel numbers is 1-1 to 999-
999. Two-part channel numbers are useful in the situation where an RF encoder/modulator is used as the channel’s source, and the output is
set for a simultaneous RF and IP stream.
The channel name is limited to seven characters.
There are three ways to enter the channel list.
Individual channels can be added using the AC command via the RS-232 serial port or Telnet.
Individual channels can be added using CR Toolbox software
A list of channels can be added by creating a text document of the entire channel list and uploading the list using CR Toolbox.
RS-232
Two commands are required when adding channels via RS-232. The channel is added using the AC command and stored in NVRAM using the
WC command. Multiple channels may be added before sending the WC command.
The order of information is UDP/RTP, multicast or unicast address, port, program ID, channel number, name.
(A colon separates all fields
except UDP/RTP and IP address octets.)
Example of the commands and the response strings from the IP-SDI 4i:
>AC=U239.27.1.101:1234:1:1:Fox
<AC=OK
>WC
<WC=OK
CR Toolbox
CR Toolbox may be downloaded from the Software Product section of the Contemporary Research website. Once launched, CR Toolbox will
look for Contemporary Research devices on the network. CR Toolbox can also connect with individual devices through an RS-232 serial port.
