The video port is covered the heat shrink tube of high shrinking ratio. After the video connection, please heat the tube to make sure the video port is damp proof and water proof.

Page 21

3 INSTALLATION

The intelligent speed dome adopts wall mount mode.

3.1 Component Installation

The wall mount bracket and IR speed dome is shown as in Figure 3-1.

Figure 3-1

3.2 Wall Mount Installation Steps

3.2.1 Installation Environments

The wall mount speed dome can be installed in the hard construction wall in the indoor or outdoor environments. Before the installation, please make sure:

 The wall is thick enough to install the expansion bolt.  The ceiling can at least sustain the 8x weight of the speed dome, bracket and the

accessories.

3.2.2 Installation Steps

1) Dig a hole of 50mm diameter for cable exit in the installation wall.

2) In Figure 3-2, connect the adapter block to the internal thread of the wall mount bracket,

until it reaches the end and then fix the set screw. Pull the intelligent speed dome composite cable through the adapter block and pull it out of the other end of the wall mount bracket. Line up the hook at the top of the external enclosure to the inside hole of the adapter block and then push it to the end, and then secure the three screws of the adapter block firmly. Please note this step is very important. Please make sure the

screws are firm, otherwise, it may result in falling risk of the intelligent speed dome.

Page 22

Figure 3-2

3) Dig holes in the wall according to the installation holes at the bottom of the wall mount

bracket. Please make sure the cable exit of the bracket is facing the round hole of the wall. Insert expansion bolts (not provided) to the holes you just dug. Connect the composition cable and then pull it through the hole in the wall. Use four hex screws and flat washer to secure the bracket on the wall of the expansion bolts. See Figure 3-3.

Figure 3-3

Now the installation is complete. See Figure 3-4.

4 APPENDIX Ⅰ LIGHTENING PROTECTION AND SURGE

PROTECTION

This series speed dome adopts TVS lighting protection technology. It can effectively prevent damages from various pulse signals below 6000V, such as sudden lighting and surge. While maintaining your local electrical safety code, you still need to take necessary precaution measures when installing the speed dome in the outdoor environment.

 The distance between the signal transmission cable and high-voltage device (or high-voltage

cable) shall be at least 50 meters.

 Outdoor cable layout shall go under the penthouse if possible.  For vast land, please use sealing steel tube under the land to implement cable layout and

connects one point to the earth. Open floor cable layout is forbidden.

 In area of strong thunderstorm hit or near high sensitive voltage (such as near high-voltage

transformer substation), you need to install additional high-power thunder protection device or lightning rod.

 The thunder protection and earth of the outdoor device and cable shall be considered in the

building whole thunder protection and conform to your local national or industry standard.

 System shall adopt equal-potential wiring. The earth device shall meet anti-jamming and at

the same time conforms to your local electrical safety code. The earth device shall not short circuit to N (neutral) line of high voltage power grid or mixed with other wires. When connect

the system to the earth alone, the earth resistance shall not be more than 4Ω and earth

cable cross-sectional area shall be below 25 mm². See Figure 4-1.

5 APPENDIX Ⅱ ABOUT RS485 BUS

5.1 RS485 Bus Main Feature

RS485 is semi duplex communication cable of impedance 120Ω. Its max load amount is 32 effective loads (including main control device and devices to be charged).

5.2 RS485 Bus Transmission Distance

When we take 0.56mm (24AWG) twisted-pair as communication cable, the max transmission distance (theoretically) are listed below (according to different baud rates).

In the following situations, the max transmission distance shall become shorter accordingly:

 The communication cable is a little bit thin;  The surrounding environment has strong electromagnetic interference;  There are too much devices connected to the RS485 bus;

And vice versa, the max transmission distance shall become longer.

5.3 The Problem in Practical Use

In practical usage, we usually adopt star type connection. The terminal resistance shall connect to the furthest two devices (Such as device 1# and device 15# in Figure 5-1 ). But this connection way does not conform to RS485 Bus standard. When the distances between devices are too long, the signal reflection occurs and anti-jamming decreases, thus the signal reliability becomes very low. You can see speed dome is not under control or speed dome is running automatically and can not stop.

Figure 5-1

In this situation, we recommend RS485 distributor. This device can turn star type connection into the connection that conforms to RS485 bus industry standard, which can avoid the above mentioned problems and enhance communication reliability. See Figure 5-2.

Page 26

5.4 RS485 Bus FAQ

Phenomenon

Possible Reasons

Solution

Speed dome can run selfdiagnosis but I can not control it.

 Host address(baud rate) and

speed dome address(baud rate) are not match;

 Positive and negative end of

RS485 Bus are misconnected;

 Connection cable is loose；  RS485 Bus connection are cut

off;

 Modify host or speed dome setup ；  Switch RS485 positive end and

negative end；

 Fix connection cable firmly；  Replace RS485 Bus.

I can control the speed dome but is not smooth

 RS485 Bus connection are not

good；

 One RS485 bus is off；  The distance between host and

speed dome is too far；

 Parallel connected too much

speed domes.

 Connect RS 485 Bus again；  Replace RS485 Bus；  Add terminal matching resistance；  Add RS485 distributor.
