Network Diagram

The network diagrams below display all the networking scenarios.
Different models of the devices have different requirements.

1. For H series VTH and F series VTO.
   When there are 6 devices (VTH+VTO) connected together, only a maximum of 2 devices can provide power output.

2. For G series VTH and S series VTO.

• When there are no more than 4 VTHs, the maximum current output of all the 12 VDC power is 500 mA.
•  When there are more than 4 VTHs, the maximum current output of all the 12 VDC power is 300 mA.
•   The power supply of HDCVI camera cannot be grounded.
• The product appearance is for reference only.

Wiring 1 VTO and 1 VTH

• The two wires connected to the positive and negative terminals of OUT cannot be short-circuited.
• The line termination terminal and branch terminal are optional in this scenario.

The DIP number of each VTO cannot be the same. Otherwise, the connection might fail. Wiring Distance Between the VTH and VTO

• It is recommended that the distance between the line termination terminal and the 2-wire controller do not exceed 3 m.
• Max distance (A) refers to the distance between the VTH and the VTO.
• Max distance (B) refers to the distance between the 2-wire controller and the VTH.

Cable Insertion Loss
Insertion loss refers to the situation of sending a signal from one end of the cable and receiving the signal at the other end of the cable.
The calculation of cable insertion loss is as follows: Insertion Loss = 20 × Log (signal received/signal sent)

The cable insertion loss followed is collected from the laboratory environment, and is for reference only. The actual data might differ from that collected in the test environment.

Installation

• Do not expose the VTO to condensation, high temperature, direct sunlight, stain, dust, and chemically corrosive substances.
• Installation should be done by professional teams. Do not dismantle or repair the VTO by yourself in case of device failure. Contact after-sales service if you need any help.
• Prepare cross screwdrivers and gloves yourself.
• The recommended installation height of the VTO should be no more than 2 m from the ground.

Basic DIP Configuration

Configure the DIP switches to achieve the function you would like to program, which includes:

• Configure the address of the VTO.
• Configure the connection mode.

6.1 DIP Switch Introduction
On the Dip-switch, set the code corresponding to the function you want to program as shown in the table below.
Table 6-1 DIP Switch mapping relations and function

Supports programing a
maximum of 14 VTO

6.2 Configuring VTO Address
This section introduces how to configure the address of a VTO through the coding rules of DIP switches.
Procedure
Step 1 Find the mapping relation between the DIP switch number and the address number you plan to configure from the table.
It follows a calculation rule that combing only the numbers listed in the Address No. only to form a new address number.
Step 2 Manually move the actuator(s) corresponding to the DIP switch(s) to the status ON, so that the address of the VTO can be configured.
For example, if you want to set your VTO address as 4, you need to first find the mapping relation (DIP 3 equals to the address number of 4) in the table, and then manually move the actuator of the DIP 3 to the status ON. If you want to set your VTO address as 3, you need to do the calculation (1+2=3; which equals to the value of DIP1 and DIP 2 combined together in the mapping relation), and manually move both the actuator of DIP 1 and DIP 2 to the status ON.
** Here is the list of commonly used VTO addresses (1-14) and their corresponding DIP switch number combinations.
Table 6-2 Common VTO Address (1-14) and DIP switch numbers**
