Step 4 — Connecting control devicesa.For control through Ethernet, connect a LAN or WAN to the RJ-45 connector(see h above). The default IP address is 192.168.254.254. The default subnet mask is 255.255.0.0.b. For serial RS-232 control, connect a host device to the 3-pole captive screw connector(see i above). The default baud rate is 9600.c.For control through USB, connect a host device to the front panel mini USB B port. (see a on page 2).Step 5 — Connecting powerConnect a 100 to 240 VAC, 50-60 Hz power source to the power AC power connector (see a above).Figure 2. Rack MountFigure 3. Furniture MountEach SideMounting Bracket2IN1606 • Setup Guide (Continued)Front Panel OverviewFigure 4. Front Panel Featuresa Front panel config port — Connect a host device to the mini USB B port for device configuration, control, and firmware upgrades.b Input selection buttons (1-6) — Press one of these buttons to select an input. The buttons light amber for audio and video, green for videoonly, or red for audio only.c Status LED indicators —Input Signal LEDs — Light for the corresponding input when active video content is detected on that input.Output Signal LEDs — Remain lit green when active video is being output, or blink amber when output video and sync are disabled.Input HDCP LEDs — Light for each input signal that is HDCP-encrypted. Analog inputs 1 and 2 cannot be HDCP-encrypted.Output HDCP LEDs — Light for an output when it is currently HDCP-encrypted.d Menu and Enter buttons — Press these buttons to access and navigate the on-screen display (OSD) menu system.e Navigation buttons — Press these buttons to navigate through the on-screen display menu system or change selected settings.f Volume knob and LED indicators — Rotate the Volume knob to adjust the variable analog audio output (default), mic, or program volume(see the IN1606 and IN1608 Series User Guide to configure the knob through group masters). The eight Volume LED indicators light in order according to the audio volume level. The bottom LED blinks when the volume is muted. They light in order from bottom to top to indicate a 12.5% increase or decrease in volume (12.5 dB) from 1% (-99 dB) to 99% (-1 dB). The top LED blinks when the volume is 100% (0 dB).Setting Front Panel Lockout Modes (Executive Modes)The IN1606 has two modes of front panel security lock that limit the operation of the device from the front panel.• Executive mode 0 — The front panel is fully unlocked. This is the default setting.• Executive mode 1 — The front panel is completely locked. This can only be enabled or disabled using SIS commands or the internal web pages (see the IN1606 and IN1608 Series User Guide for web page details or the rear page of this guide for the SIS command).•Executive mode 2 — The front panel is locked except for input switching and volume control. Press and hold the Menu and Enter buttons simultaneously for 3 seconds to enable or disable this mode.Configuring the IN1606The IN1606 can be configured through front panel controls and the OSD menu, the internal web pages, the Extron Product Configuration Software, or SIS commands. To access the internal web pages or send SIS commands, connect a host device to the IN1606 via RS-232, USB, or Ethernet connection (the internal web pages can only be accessed through an Ethernet connection).On-Screen Display (OSD) Menu SystemThe IN1606 has an OSD menu consisting of nine submenus that can be accessed using the front panel Menu or Enter button. View the menu on a display connected to either HDMI output connector (see f on page 1).

– The channel coding scheme for transport blocks in LTE is Turbo Coding with a coding rate of R=1/3, two 8-state constituent encoders and a contention-free quadratic permutation polynomial (QPP) turbo code internal interleaver. Trellis termination is used for the turbo coding. Before the turbo coding, transport blocks are segmented into byte aligned segments with a maximum information block size of 6144 bits. Error detection is supported by the use of 24 bit CRC. – Coexistence scenarios have been already done for the downlink and result can be found in TR 36.942

物联网在智能交通中的应用英文版
物联网作为新一代信息技术的重要组成部份,通过射频识别,全世界定位系统等信息感应设备,依照约定的协议,把任何物体与互联网相连,进行信息互换和通信。随着物联网技术的不断进展也为智能交通系统的进一步进展和完善注入了新的动力。
在以上研究背景下,咱们提出了现有智能交通系统模式所存在的问题与不足,并探讨了研究物联网环境下智能交通系统模型与架构的意义;第二,通过度析现存问题,论述智能交通系统引入物联网技术的必要性。
After considering the existed problem, we point out the necessity of lead-in the IOT into intelligent transportation.
【Key Words】Intelligent Transportation System;Internetof Things; System Architecture; Evaluation.
Nowadays, the road network of Shenzhen has formed a net pattern with the several decades of building and improving. Because of the increasing urban population, the constitution of ITS has become the only way to sustain the Shenzhen's transportation. The ITS is the orientation of future transportation.
