DIGITUS® 4-Port Gigabit Network Switch, 1 SFP Uplink.

The product provides high-speed packet forwarding capability and

ample backplane bandwidth to ensure clear and smooth image

transmission. It is embedded in static electricity and surge

protection circuit to improve product stability. It also supports VLAN

configuration mode, which enables network storm suppression,

protects security information, and prevents the spread of viruses

and network attacks. It fully meets the requirements of network

video surveillance system.

5.3 DIP switch

The switch defaults to the standard network mode at the factory,

and the dial keys ①and ②are in the off position. After the device

is power on, all of ports are interoperable.

One-to-one isolation: Dial key ①to on position, dial key ②

default off position. After the device is power on, it starts the one-

to-one isolation mode configuration and implements the

corresponding ports of the two ports. In this case, the ports on the

same device cannot be forwarded to each other. They can only

communicate with the corresponding port on the peer device.

Port Isolation: Dial key ②to on position, Dial key ①default off

position. After the device is power on, port isolation is achieved. The

RJ45 ports cannot communicate with each other, the

communication takes place between the SFP port and the individual

RJ45 ports.

Long distance mode: Dial key ①and ②to on position. After the

device is power on, the long-distance mode configuration is enabled

and the electrical port rate is 10Base-T. The transmission distance of

the electrical port is increased. At this time the device port

transmission distance of 0-330 meters.

Notes

1 to 1 isolation mode must require two identical

switches, through the optical port docking network can

be used.

6. Important function

6.1 Port Isolation

The switch cannot carry out data transfer between each other, only

to the optical port to communicate, so the data conversion more

efficient, the system is running more secure.

6.2 One-to-one Isolation

When two switches A and B are connected through the optical

interface, the A switch port 1 can only communicate with the B

switch port 1. Similarly, A switch port 2 can only communicate with

B switch port 2, and so on. To establish one-to-one isolation mode

between A and B switches’ RJ45 ports, it requires 2pcs of same

switch. It prevents the network storm, eliminating the paralysis of

the system.

6.3 Long distance mode

By default, the switch electrical port transmission distance of 0-100

meters, open long distance mode, the electrical port for 10Mbit/s,

to meet the high-definition video transmission bandwidth while

increasing the maximum transmission distance of 330 meters. Thus

enabling the ability to install IP cameras at the front of the field.

7. Installation

7.1 Precautions

When placing the switch, please pay attention to stability, drop will

cause serious consequences.

Should be in the correct power supply to work properly, please

confirm before using the power supply and switch the power

requirements specified in line.

To reduce the risk of electric shock, do not open the case when the

switch is working, even if it is not charged, do not open it yourself.

When the switch works, the network cable can be inserted or pulled

out at the port without interrupting the work of the switch.

Before cleaning the switch, pull the switch's power plug first, wipe it

with a moisturizing fabric, and do not use liquid cleaning.

Do not place the switch in a watery or humid place and prevent

water and moisture from entering the switch housing.

When placing the switch, please avoid dusty and strong areas of

electromagnetic interference

7.2 Install style

There are two install methods that can be installed on the desktop

and wall mounted.

Notes

This product does not contain other fixed accessories

other than fixed mounting screws;

When installing or moving, please unplug the power cord.

7.2.1 Install to the desktop

You can place this product directly on a clean, solid, grounded desk.

7.2.2 Wall mounted

You can also place this product on a clean, solid vertical wall. The

installation process is as follows:

1. Fix the mounting brackets with screws

2. Insert the capsules into the holes on the wall. (The capsules are not

included in the package.)

3. Insert the screw into the hole of the dowel. Please use screws with

a diameter of 3-5 mm. Fix the network switch with the screws.

8. Connect the cable

1) Before installation, please turn off the power of each signal

source and the device to be displayed. The installation of the

power supply may cause damage to the transmission equipment.

2) Use the network cable to connect the network camera and

the 1-4 Electrical port of the device respectively;

3) Connecting the optical fiber interface of the device with the

optical fiber interface of the uplink equipment using the optical

fiber line.

4) To connect the power supply equipment.

5) Check whether the installation is correct, equipment damage, to

ensure that all connections are reliable, to the system power.

6) To confirm whether the network equipment, power supply,

work is normal.
