Introduction
The VCX-4400-E and the -ER are the chassis versions of the Core Tec stand-alone VCX­4400 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 sub­channels, 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.
FamiliarizationwiththeVCX4400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.

ComPortDataInterface
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. system software.
Refer to Appendix A for the correct pin out
.
Com Port parameters are configured through the
VideoInputInterface
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

MountingtheEncoder
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.
QuickStart
IfuserwishestoconfiguresettingswithVCX4400EviaCOMPortorNetwork:
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:
Telnet192.168.0.253 <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.

UpdatingFirmwarewithVCXNetBurner
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.
NOTE: It is important that a VCX-2400 device that has a Failed status NOT be turned off or rebooted. At the point that the failure occurs the device will not be in a bootable state. If power is cycled or the firmware cannot be updated without failure after repeated attempts then the firmware chip will need to be replaced. The 10Mbps revision 2.5 devices (in current production) have removable chips that can be replaced in the field. The 100Mbps revision 3.0 devices must be reprogrammed at the factory. Since revision 3.0 is not yet in production there may be other safeguards, such as automatic firmware backup that may modify these instructions.
When a device is in the process of upgrading, the Activity screen will show the progress as a percent of complete for each stage. There are four stages.. 1) Erasing, 2) Startup Code, 3) Application Code, and 4) FPGA. When erasing the progress may not update but erasure will compete in a few seconds. The startup code frequently completes so quickly that you don’t see it in the Status column.
After the FPGA status reaches completion you should see the Status column change to Complete. If it changes to Failed at any time during the firmware update you will need to retry updating the firmware for that unit before cycling power or rebooting.
The Clear Complete button will clear the list display of any operations that did not fail. The Clear Failed button will clear the list display of any failed operations. The Initiate Update will Broadcast a command to all online units to connect to the update server to perform a firmware update. Normally the update server will be the computer that is running VcxNetBurner. However it would be possible to have VCX-2400 devices configured to use a different server. When Initiate Update is pressed, all of the VCX-2400 devices within range of multicast packets will connect to its preset update server.
VCX2400D Screen
The VCX2400D is accessed through the VCX-2400D tab and displays the parameters used to select the version of the firmware sent to VCX-2400 decoder devices. This information is imported from a import.ini file that is provided with each firmware update. This screen allows the operator to see what update is selected. It is important to confirm that the files indicated in the file selection boxes are located on your computer. The import file is selected using the
menu’s File- >Import option. This is explained later in this document. The Apply button saves the current setting on this screen so that when VcxNetBurner is loaded these parameters are restored. The Revert button will reload the currently saved parameter set. So if you have modified this screen it can be restored if you haven’t used apply.
The Encoder Screens- VCX2400E, VCX440E, & VCX6400E (2/4/J-E)
The Encoder screens are accessed through the VCX2400E, VCX440E, & 2/4/J-E tabs and work identically the same as the VCX-2400D, except that the parameters are applied to the firmware sent to the VCX-2400, 4400, or 2/4/J Encoder devices.
