1.1 Product Advantages

TB 2 I is s p e c ia lly d e sig ne d fo r e le va to r wire les s vid e o transmission and customized

products; c o mpared with the trad itional elevato r video trans m ission prod ucts, it has the

fo llo w ing a d va n ta g e s :

1. G ood anti - jam min g ab ility

Super low frequency power supply interference, electrical spark interference, inverter motor interference, control signal interference etc. that below tens of kilohertz are found in the elevator environment, the use of W IFI high-fre q u e nc y trans m iss io n , c a n e ffec tiv e ly avoid the interference of elevator environment. At the same time the device supports extended frequency, can avoid the same frequency interference in the traditional WIFI.

2. Short construction period

In the absence of a large amount of wiring work, so greatly shorten the construction period, save a lot of human resources.

3. Embedded VTrans technology

TB2I devices is embedded with VTrans technology, including TDMA, 20M/40MHz b a nd wid th , in te llig e n t ra te c o ntro l, A uto A C K T ime -out adjust. It makes the device have longer transmission distance, higher throughput and better point-to-m ulti-po int p e rfo rm anc e.

4. Embedded hardware watchdog

TB2I is embedded with hardware watchdog, which is used to monitor the working status of the device. Once the system is not working properly, the device can be rebooted to guarantee the stab ility o f the system.

5. M o re N o n-standard channels availability

C u rre ntly mos t of the WIFI devices are working at standard 802.11 5.8G Hz frequency. However, standard 802.11 5.8G Hz only provide limited channels, and there is serious interference if there are a lot of 5.8GHz WIFI devices nearby. TB2I support more channels near 5.8GHz band, and spread the band to non-standard frequency part. The advantage of working at the non-stand ard band is to avo id the inte rference in the stand ard channels, and the wireless throughput can be improved.

N o te:

Please confirm whether those non-standard cha n nels are p e rm itted lo c a lly b e fo re

using them.

To use the TDMA, the user needs to enable TDMA mode in the AP device, and set a priority level in the station device. When several stations are connected to one AP, different clients demand different throughput. If the client demands higher throughput, its priority level can be set to High, otherwise set to Low. When the client demands the same throughput, their priority level can be set to the same level.

1. The device cannot be started after power on.

① The Ethernet cable between the device and the PO E adaptor is more than 40 meters

③ The RJ-45 plugs are not well connected.

2. Forgot the IP address of the device.

Please manually push the Reset button for 5~10 seconds and wait 2 or 3 minutes, then the user can log in the device by typing the default IP address

192.168.1.36/192.168.1.35.

3. How to modify the IP address of the device?

Please open the device page, followed by click Network - > interfaces - > s e le c t E d it button of the LAN interface - >Common C onfiguration - >G eneral Setup ->IPv4 address; here you can set the IP address according to your own needs.

settings which will cause the same frequency interference. It is recommended to

separate the frequency of the devices. If the channel width is 20M, the frequency

difference between two devices should be more than 20MHz. For example, 2412MHz,
