Introduction
The model VCX-4402-E is the stand-alone Dual MPEG-4 version of the VCX family and is
housed in a 19-inch 1U rack mount case with a display, control port and a universal AC power
supply. The configuration of the VCX-4402-E-H is akin to desktop like devices being 1U high
but only 8.5 inches wide. The model VCX-4402–E-R is a rack mounted card only used in the 4U
19-inch rack unit. See Accessories R-12.
The VCX Digital Video transport system consists of the video encoder and a decoder. These
will make up an encoder/decoder pair providing the capability for one-way end-end transmission
of the compressed digital video stream in one of two formats. The format is MPEG4 standard
ISO/IEC 14496. The transportation process is performed by transmitting and receiving IP
packets at data rates in the 64 kbps to 4.0 Mbps range. The encoding-decoding process is applied
to an NTSC (or PAL) video input, selected in software.
The video encoder converts the Analog Video to a Serial Digital 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 of video format and resolution, data sub-channel characteristics, and basic IP
parameters is achieved through one of the following means:
a) A terminal Program
b) Telnet through the Ethernet connection
c) Watchdog CCS Software
d) SNMP
e) Web Interface
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 (support for RS-232 or RS-422) and a
separate front-panel terminal port. Sub-channel information is removed from the video stream by
the encoder thus completing the control link back to the decoder that is supplying the pan-tilt-
zoom commands.

Familiarization with the VCX4402-E
The VCX-4402-E Video Encoder accepts two BNC video input and two data sub-
channels. The output from the encoder is a stream of IP-packets. The Full Width (19”) Encoder
also contains a fluorescent LED display to allow monitoring of unit performance and to facilitate
troubleshooting.
The VCX-4402-E Video Encoder has a programmable reset, which prompts the re-
initiation of the video stream, as well as a reboot command. 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 (full size encoder only)
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:

Mounting the Encoder
The VCX-4402-E Encoder is a 19-inch wide 1U unit and is furnished with mounting ears
allowing installation in a 19” rack frame. The VCX-4402-E-H is a desktop like unit that is 8.5
inches wide and designed to be a shelf model without the need for mounting. However if you
choose to mount the half size model, extended mounting ears are available. The VCX-4402-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 Hyper Terminal.

Quick Start
If user wishes to configure settings with VCX4402-E via COM Port or Network:
Set up for COM Port:
User may configure VCX4402-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-4402-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-4402-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
VCX-4402-E Installation and Operating Instructions Page 8
Having used either of these methods, the encoder is ready to receive configuration
commands.
Main unit configuration
The VCX-4402-E units incorporate support MPEG-4 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 three 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 an
example. Locate two MPEG4 encoders.

Updating Firmware with TFTP
TFTP is a simple and reliable way of updating the firmware on any device. All that is required is to have
access to a TFTP server which will be used as the host and contain the necessary files. (An example file
name is VCX4402e.ctc).
Via Telnet, enter the following command in order to update the firmware for the device that is being used.
TFTP <File Name> <Server IP Address>
(File Name is the name of the file which contains the firmware update information. In order to receive the
latest update files, please contact Coretec.)
Here is an example of what a successful update will look like:
This is an example using the 6400E, but the method is the same for the 4402E
This is the command

IP Configuration
Overview
The commands contained in this section provide the means to configure critical network,
com ports, encoder, and decoder parameters. The user should consult the factory if specific
functions of interest do not appear to be supported.
Initial IP Addressing
To set the device parameters properly, encoder and decoder units must be given appropriate
IP addresses, compatible with the network on which they are to be connected. The software
module VXNETCONFIG was developed to allow a network administrator to set the IP and
Subnet in the VCX-4402 series encoders and decoders.
1) Installation
To load VXNETCONFIG insert the CORE TEC CD into your CD drive. Select
VXNETCONFIG by double clicking on the program. The following window will open:
