Introduction
The VCX-4400-E and the -ER are the chassis versions of the Core Tec stand-alone VCX-
4400 MPEG-4 IP product series. These units are fully compatible with the “-ER” card cage
versions of the product series.
The VCX-4400 Digital Video Codec system consists of a video encoder and a Core Tec
decoder pair providing the capability for one-way end-end transmission of compressed digital
video in IP packets at data rates in the 64kbps to 3.5 Mbps range.
The system employs MPEG-4 encoding. The encoding-decoding process is applied to an
NTSC (or PAL) video input, selected in software.
The video encoder converts the video to a serial signal, which is multiplexed with any
data sub-channels present. The stream is then formatted into a series of IP packets sent to the
network through a standard Ethernet connection.
Modification to video format and resolution, data sub-channel characteristics, and basic
IP parameters are achieved through one of the following means:
a) a Hyper Terminal accessible menu
b) Telnet through the Ethernet connection
c) Watchdog CCS
The video decoder receives the IP packets, separates the video data from the data sub-
channels, and converts the video data to analog form, providing an NTSC (or PAL) output.
The units feature two bi-directional data sub-channels (programmable for RS-232 or RS-
422). Data bits are multiplexed with the digital data stream.

FamiliarizationwiththeVCX4400E
The VCX-4400-E Video Encoder accepts one video and two data signals. The output
from the encoder is a stream of IP- packets. It also contains a fluorescent LED display to allow
monitoring of unit performance and to facilitate troubleshooting. The encoder has a
programmable reset, which prompts the re-initiation of the video stream as well as a reboot
command.
The VCX-4400-D Video Decoder accepts the signal from the network originally generated by a
VCX-4400-E video encoder. The unit effectively decompresses this data stream and re-creates
an analog waveform in NTSC (or PAL) video format. The unit supports the bi-directional data
transmission of two data sub-channels, corresponding to the encoder. The unit also features an
LED display. The decoder also has a programmable reset command, tied to errors in the
incoming video stream, as well as a reboot command.

ComPortDataInterface
There are two bi-directional data interfaces, RS-232 and RS-422 selectable, on the encoder and
decoder assemblies. Each interface uses RJ-45 connectors. Refer to Table below for the correct pin out.
When using the RS-232 configuration pin 7 is ground. Com Port parameters are configured through the
system software.
Refer to Appendix A for the correct pin out.
VideoInputInterface
Connect a BNC-terminated coaxial cable from a composite video source (e.g., CCTV camera) to
the BNC connector labeled “VIDEO IN” (encoder). The composite video input should be in NTSC or
PAL format. The maximum length of cable that should be interfaced to the encoder or decoder is 100 feet,
although the specific installation environment will dictate the actual permissible length.
EthernetInterface
There is one Ethernet interface for encoder or decoder, which uses a standard RJ-45 connector.
The standard method of terminating an ETHERNET cable reflects the TIA568A standard
(Telecommunications Industry Association standard).
Refer to Appendix A for the Straight Through and Crossover Ethernet Pin Out.
Power
Power is applied through a standard IEC type detachable line cord at the rear of the unit. The unit
automatically senses 110 VAC or 220 VAC supply and will operate with either. The typical current is 1.2
amps from a 110VAC line and drops to .9 amps from a 230 VAC line source.
Display
The fluorescent LED display (Full Width 19” Encoder only) provides a scrolling list of key
parameters when the unit is in its active (non-stand-by) state.
The display is a two-line display. Each parameter is displayed, in turn, for three seconds
on the bottom line. It then moves to the top line while the next parameter is displayed on the
bottom line.
The parameters displayed are as follows:
Name of unit
Software version
Device IP address
Sub-net mask

Video IP (multi-cast group)
Group Length
FPS (frames per second)
Maximum Bit Rate (encoder only)
Audio On or Off
Com 1 On or Off
Com 1 Bit Rate
Com 1 IP
Com 2 On or Off
Com 2 Bit Rate
Com 2 IP
MountingtheEncoder
The VCX-4400-E Encoder is a 19-inch wide 1U unit and is furnished with mounting ears
allowing installation in a 19” rack frame. The VCX-4400-E-H is a desktop like unit that is 8.5
inches wide and designed to be a shelf model without the need to mounting. However if you
choose to mount the half size model, extended mounting ears are available. The VCX-4400-E-R
is a single card for use in the multi-card chassis, which is a 19-inch 4U unit that will support 12
cards.
All signal connections are from the rear, eliminating any need for setback from the front
plane of the rack. The user programming port on the front panel is used to alter system
parameters via a Terminal Program such as HyperTerminal.
QuickStart
IfuserwishestoconfiguresettingswithVCX4400EviaCOMPortorNetwork:
Set up for COM Port:
User may configure VCX4400-E setting using a PC connected to the encoder
control port at the front of the unit. A simple 6-wire phone cable (PCA-2400
programming cable) with the RJ-11 adaptor described in Appendix A will supply the
proper RS-232 connection to the PC’s serial port. Note: This is not the same as the “Sub-
Channel” interface. Do not use the RJ-11 adaptor for this channel.
This configuration will permit the unit configuration by a terminal program running on a
PC. Once you have connected the encoder to the PC’s serial port open your terminal
program. The encoder will boot up then ask for a password. The default password is:
admin.

The PC should have its Com Port configured as:

Baud rate 38,400 kbps
Data bits 8 bits
Parity No Parity
Stop Bits 1 Stop Bit
Flow control None

Refer to Appendix A for pin layout for RJ-11 connector.

Set up for network:
If the operator wishes to configure the unit through the network the user may
accomplish this by the following procedure. Note: The operator must be sure that the
VCX-4400-E is accessible on their SUBNET. Before completing this step, please refer
to the Programming Configuration Section of this Manual. Here you will set the IP
address and SUBNET Mask of the VCX-4400-E so that it is accessible on your SUBNET
and has a valid IP address. (An example IP address is being used in the following
example.):
Open a “cmd” window and enter the following commands:
Telnet192.168.0.253 <enter>
The encoder will reply asking for a password. Default password is “admin”.
Password: admin
Having used either of these methods, the encoder is ready to receive configuration
commands.
Main unit configuration
The VCX-4400-E units incorporate support for one form of encoding from two different input
channels. It is important the operator understand this to be able to configure the unit properly. All
commands follow this simple format:
(command<space>parameter<enter>)
From the command prompt, the operator may view the current configuration by entering the
“display” command. This will dump the entire configuration status for the selected encoder. Remember
there are two encoders in one unit. Enter the following configuration for each of the encoder channels.
Take note the IP address must be of valid encoders on the network. The IP addresses below are just used
as an example. Locate an MPEG4 encoder.

UpdatingFirmwarewithVCXNetBurner
Introduction
VcxNetburner is a Windows 2000/XP application that allows updating of the VCX-2400
Encoder/Decoder firmware (as well as the VCX4400E and VCX6400E.) VcxNetBurner can
simultaneously the firmware of all VCX-2400 devices that can be accessed on your network. If
you can telnet to the device then VcxNetBurner can update the firmware. The only exception is
that the device’s current firmware version must be v1.5 or higher. Firmware v1.4 does not
contain the update feature.

Overview
VcxNetBurner has a few interface features that the user should be familiar with before
attempting to update a device. The basic steps are… 1) import the firmware description, 2)
broadcast the server IP, and then 3) initiate the update. However the user needs to be aware of
the general process, optional steps, potential problems, and what to do in the case of an error. We
will start with an overview of the user interface.
Screens
The Activity Screen

The Activity screen contains a list of the current activity and a history of past update operations.
A VCX-2400 device that has finished updating with indicate either 1) Complete, 2) Version
Current, or 3) Failed. The Device column lists the serial number of each unit that is responding
to the update command.
