Connecting a Serial Device
This section explains how to connect an RS-232, RS-422 (four-wire) or RS-485 (two-wire or
four-wire) serial device to the EV Series device.
RS-232, RS-422 and RS-485 are communication standards between a Data Terminal
Equipment (DTE) and a Data Circuit-terminating Equipment (DCE) using the asynchronous
serial communication method.
Most serial equipment, such as PTZ cameras, keyboards, matrixes, multiplexers, or access
cards, conforms to the RS-232 or RS-422/485 standards. EV Series devices support the RS232, RS-422, and RS-485 asynchronous protocols using pluggable screw-terminal strips. For
any other protocol, you may need a converter.
NOTE: The EV Series devices come with a terminal block plug to attach RS-232 and
RS-422/485 devices.
21
DVTel EV Series User Manual
5.3.3.1
Connecting RS-232 Devices
The RS-232 standard is used in some analog cameras and computer serial ports. Before
connecting the EV Series device to RS-232 serial equipment, determine if they are DTE (Data
Terminal Equipment) or DCE (Data Circuit-terminating Equipment).
When connecting two modules of the same type (for example, DTE to DTE), you need a
cross-cable for communication. When connecting a DTE with a DCE, a straight cable is
required.
22

2.) Using Network Video Management System (NVMS): You can use any VNMS, such as Latitude,
to configure the device.
CAUTION: Any changes made using Latitude software will override the changes made
using Device Configurator or the Web Interface.
3.) Using the Web Interface: The EV Series devices have a self-contained web server allowing you
to connect directly to them via a web browser. The Web Interface is a browser-based tool that
allows you to configure the EV Series devices. For complete information on the Web Interface,
refer to the Web Interface User Guide.
NOTE: The default username and password for the Web Interface is admin. We
recommend that you change the default password for the edge device to a more
secure password.
6.1
Obtaining and Setting the IP Address
By default, all DVTel EV Series devices are APIPA (Automatic Private IP Addressing)-enabled.
The APIPA scheme, available on the Windows operating systems, allows a device to assign
itself a temporary IP address until it receives a complete network configuration, either
manually or from a DHCP server.
A device in APIPA mode does not reside on the same subnet as the other devices on the IP
network. Therefore, it may not be able to view or be visible by the other devices. All DVTel
edge devices use the following temporary APIPA configuration:

IP address: 169.254.X.Y (where X and Y are based on the last two octets of the
MAC address of the device)

Subnet mask: 255.255.0.0

Gateway: 169.254. *. *

bus or star topology and supporting data
transfer rates of 10, 100, and 1000 Mbps. It is
one of the most widely implemented LAN
standards. The 802.11 protocols are often
referred to as “wireless Ethernet.”
Firmware
Software stored in read-only memory (ROM) or
programmable ROM (PROM), therefore
becoming a permanent part of a computing
device.
H.264
Also known as MPEG-4 AVC (Advanced Video
Coding), H.264 is a video compression standard
that offers significantly greater compression than
its predecessors.
IP
(Internet Protocol) The network layer for the
TCP/IP protocol suite widely used on Ethernet
networks.

spans a relatively small area. A LAN can
connect workstations, personal computers, and
surveillance equipment (like edge devices). See
also WAN.
PSK
(Pre-Shared Key) A mode of the WPA and
WPA2 security protocols, designed for home
and small office networks that cannot afford the
cost and complexity of an authentication server.
It is also known as personal mode.
Multicast
Communication between a sender and multiple
receivers on a network. The devices can be
located across multiple subnets, but not through
the Internet. Multicast is a set of protocols using
UDP/IP for transport.
PTL
Push-To-Listen. In a two-way system, this is the
communication mode in which the listener must
push a button while listening.
PTT
Push-To-Talk. In a two-way system, this is the
communication mode in which the talker must
push a button while talking.
NTSC
(National Television Standards Committee) The
North American standard (525-line interlaced
raster-scanned video) for the generation,
transmission, and reception of television signals.
In addition to North America, the NTSC standard
is used in Central America, a number of South
American countries, and some Asian countries,
including Japan. Compare with PAL.
PTZ Camera
Pan-Tilt-Zoom. An electronic camera that can be
rotated left, right, up, or down as well as zoomed
in to get a magnified view of an object or area. A
PTZ camera monitors a larger area than a fixed
camera.
QoS
Quality of Service. A set of low-level networking
protocols that give higher priority to more
important data flows while ensuring that the less
important ones do not fail.
NTP
(Network Time Protocol) A protocol designed to
synchronize the clocks of devices over a
network.
OSD
On-screen Display. Status information is
displayed on the video monitor connected to a
receiver edge device.
Receiver
A device that converts a digital video signal into
an analog form. Also called decoder.
Repeater
A range extender for wireless links.
PAL
(Phase Alternation by Line) A television signal
standard (625 lines) used in the United
Kingdom, much of Europe, several South
American countries, some Middle East and
Asian countries, several African countries,
Australia, New Zealand, and other Pacific island
countries. Compare with NTSC.
RF
Radio Frequency. Any frequency within the
electromagnetic spectrum that is associated with
radio wave propagation. When a modulated
signal is supplied to an antenna, an
electromagnetic field is created that is able to
propagate through space. Many wireless
technologies are based on RF field propagation.
PEAP
Protected Extensible Authentication Protocol. A
method to securely transmit authentication
information, including passwords, over a
wireless network.
RS-232
A standard interface approved by the Electronic
Industries Alliance (EIA) for connecting serial
