Introduction
The model VCX-7401 is the stand-alone H.264/MPEG4 version of the VCX
family and is housed in a 8.5-inch 1U rack mount case with a control port and a
universal AC power supply.
The VCX Digital Video transport system consists of two video encoders, H.264
and MPEG4, and a decoder. This makes up the encoder(selectable)/decoder pair
providing the capability for one-way end-end transmission of the compressed
digital video stream in the H.264 format. The encoding-decoding process is
applied to an NTSC (or PAL) video input, selected in software.
Modification of video format and resolution, data sub-channel characteristics, and
basic IP parameters is achieved through one of the following means:
a) Terminal Program
b) Telnet through the Ethernet connection
c) Web Interface Applet
d) SNMP
NOTE: The VCX7401 is optimized for encoder or decode operation. While both
the encoders and decoder can be used simultaneously, it is not recommended as
perfomance issues may occur. The exception is using the decoder to view it's
own H.264 stream, as this has minimal affect on performance.

Familiarization with the VCX-7401
The VCX-7401 Video Encoder accepts one BNC video in, one BNC Video Out
and one data sub-channel. The encoder has a programmable reset, which prompts
the re-initiation of the video stream. 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 is one bi-directional data interface, RS-232 and RS-422 selectable, on the encoder,
which uses a RJ-45 connector. Refer to Table below for the correct pin out. When using
the RS-232 configuration pin 4 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 0.9 amps from a 230
VAC line source.
Mounting the Device
The VCX-7401 Encoder is a 8.5 inch wide device and provides holes for
mounting onto a chassi. The unit can be mounted in any orientation.
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
update file, which is named vcx7401.tgz.
Via Telnet, enter the following command in order to update the firmware for the device
that is being used.

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-7401.
• 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:

Description of Program Functions
(a) The first box on the left hand side of the window displays the current IP
address of the CORE TEC device being interrogated. Type the new IP
address into this space
(b) The second box is used to change the SUBNET address. Note that the address
displayed is always 255.255.255.0. Type the new SUBNET address into this
space.
(c) The Enable DHCP box is checked when DHCP is to be enabled.
NOTE: DHCP is not currently enabled on the VCX-7401. Selecting DHCP
Will have no affect.
NOTE: Do not enable DHCP if sub-channels are being used of if there is no
DHCP server. Check with the Network Administrator, or call Core Tec
Tech Support if further assistance is needed.
(d) The Configure button is to execute the requested changes to the IP and
SUBNET information. Note that future queries of the SUBNET will indicate
255.255.255.0. Therefore, the correct SUBNET address should always be
entered prior to using the Configure button.
(e) The box on the right hand of the window displays all VCX-7401 devices
(encoders and decoders) on the network.
(f) To make a change to the equipment addressing perform the following
steps:
(g) Select the Core Tec device address from the list in the box on the right side of
the window.
(h) Move the cursor to the IP box and select the first octet by highlighting the
octet. Enter the new IP data for the selected octet. As the 3 digits are entered,
the software will automatically highlight the next octet for change. Complete
entering the IP address and then switch to the SUBNET data.
(i) Move the cursor to the SUBNET box and select the first octet by highlighting
the octet. Enter the new SUBNET data for the selected octet. As the 3 digits
are entered, the software will automatically highlight the next octet for
change. Complete entering the SUBNET data.
(j) To execute the change press the configure button. The IP address and the
SUBNET will be updated in the selected Core Tec equipment. The new IP
8
address will be displayed. The SUBNET will display a default class CSUBNET there is no read back of the changed SUBNET displayed.
