Introduction
The model VCX-2401-E is the stand-alone MPEG-2/JPEG 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-2401-E-H is akin to desktop like devices being 1U
high but only 8.5 inches wide. The model VCX-2401–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 three formats. The two formats are
MPEG2 standard ISO/IEC 13818-2 and JPEG standard ISO 10918-1. The transportation process
is performed by transmitting and receiving IP packets at data rates in the 64kbps 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) Terminal Program
b) Telnet through the Ethernet connection
c) Watchdog CCS
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 VCX2401-E
The VCX-2401-E Video Encoder accepts one BNC video and one data sub-channel.
The output from the encoder is a stream of IP-packets. The Full Full Width (19”) Encoder 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.
The VCX-2401-E 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:
Name of unit
Software version
Device IP address
Sub-net mask

Mounting the Encoder
The VCX-2401-E Encoder is a 19-inch wide 1U unit and is furnished with mounting ears
allowing installation in a 19” rack frame. The VCX-2401-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-2401-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 VCX2401-E via COM Port or Network:
Set up for COM Port:
User may configure VCX2401-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-2401-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-2401-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.

VCX-2401-E Installation and Operating Instructions Page 8
Main unit configuration
The VCX-2401-E units incorporate support for three different forms 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 an
example. Locate a MPEG2 and a system to be used as the JPEG file server.
