Glance RB800 Wireless Router

Glance RB800 Wireless Router

the emergence of new product variants echoed by Mikrotik RouterBOARD continue during 2009. Which begins with the famous RB750 with Best Value Router and Router Tiny then followed with RB750G already using Gigabit Ethernet. Both are variants RouterBOARD 700 series are almost the same as 400 Series ie use the same processor architecture Atheros but different type, which is intended for low-end router class. In the same year also released a Mikrotik Routerboard High-end class that RouterBOARD 800 series codenamed RB800.

RB800

RouterBOARD 800 series looks like a continuation of the RB600 which does have the dimensions and specifications are almost the same, but if viewed in more detail the specification RB800 RB600 almost doubled and more complete with some additional expansion slots for hardware-latest hardware that previously did not exist in RB600 .

Processor

RB800 which uses MPC8544 network processor (Freescale PowerPC-based processor) has a speed of up to 800MHz and 1GHz can dicustom (999Mhz) is currently the most powerful processor for the category Wireless Router. With heatsink and processor HeatFan the case of the overhead guard is one of the innovations that Mikrotik Router Performance can be maximized. Function "Health System" (Temperature and Voltage) is also added in the RouterOS software to allow a user to monitor the Wireless Router.

Expansion Slot

With the availability of high Resource RB800 ready to carry out all the functions available in RouterOS, flexibility becomes a crucial point in a router device then the RB800 already prepared several options for an expansion slot is a function of RouterBOARD. Like its predecessor Doughterboard Slot RouterBOARD series that always accompanies High End, on the RB800 Doughterboard slot available two versions of the standard PCI slots Doughterboard support for Doughterboard series predecessor (RB564, RB502, RB604 and RB816) and also Doughterboard PCIe type.
Slot MiniPCIe also been provided to supplement the RB800 with the latest hardware.

Performace

The high specifications on the RB800 is not only on paper brochure, but also need to be proven, we have done tests using Core2Duo machine and RB44GV. The results were very satisfactory with traffic of 250 ~ 300 Mbps full duplex, with the traffic load can remain operational oprtimal RB800 and temperature remained normal.

By doing Customisasi RB800 processor clock can be bypassed traffic predicted greater than 300Mbps.

Variations Car Computer Development

Variations Car Computer Development

Imagine, in your car there is a computer that allows it to perform a variety of jobs, enjoy the entertainment along the way, and have a digital map when you start to get lost on the way. Your friend can still say hello via chat applications like Yahoo Messenger.

The various facilities currently can be done with the help of computers installed in the car. Computer car is no longer difficult to be realized. You will be much helped, because additional features can be installed in the car computer, according to taste and needs.

To find a range of possibilities that can be done with the car computer, the tests on the 2005 Honda CRV. Been loaned this car by PT Honda Prospect Motor to the Foundation Airputih while working at the disaster site in Aceh (2005) and Yogyakarta (2006).

Hardware

The main hardware in this system is the central processing unit (CPU). To facilitate the installation of production casing Trivia use the same standard in the car audio device (measuring 1 din, 17.78 cm wide and 5.08 cm high), so no need to do a lot of modifications to the interior of the car.



The motherboard used Mini-ITX size (17 cm x 17 cm). To reduce the heat, chosen motherboard medium speed, namely the VIA EPIA M6000, using VIA Eden 600 MHz processor, reliably enough to run applications based on Windows XP.

For storage media, used 40 GB 2.5-inch hard drive, which is designed to be more shock resistant than regular 3.5-inch hard drive. CPU is also equipped with a DVD player.

At the front of the computer there are two USB ports version 2.0, to install a variety of devices that conform to the USB standard. We can use a USB keyboard for typing. Data transfer can be done from or to a USB Flash. Bluetooth connection is obtained by attaching a bluetooth interface to the USB slot.

Connection to the internet using GPRS or CDMA can be done by connecting the phone to a USB port. While the car is running, we can connect to the internet while it is within the scope of the service provider.



Monitors are used also has a 1 din size, so it can be mounted easily on the car tape holder. When not in use, the screen folds and into the box, similar to the workings of a TV that has a lot of used cars. Although the computer can be connected to a TV monitor, you should use an SVGA monitor with a resolution up to 468 x 800 pixels (wide type) 7 inches in diameter.

To make it easier to control the computer, the monitor also function as a touch screen for a replacement mouse. With the touch of a finger, can do some simple functions, for example to enable the music player application, or adjust the volume of music played.

The touch screen can be written, such as the use of graffiti feature on PDA, as a replacement keyboard for typing. Operating system Windows XP Tablet PC version an attractive choice because it is designed to optimize the use of touch-screen computers.

The electrical system

Differences car computer with a regular computer is the electrical system. Computers use a power supply unit that will transform 220 volt AC current into 12 volt DC electric current.

In the car there is a 12 Volt DC power source, but the quality of electric cars depends on engine rpm, causing unstable flow. To overcome this problem, use a power supply unit that is designed for cars. Devices M2-ATX power supplies production mini-box.com able to work with power supplies ranging from 6-24 Volts.

The power supply unit can detect when the engine dies, and set the computer to enter hybernate mode. A few minutes later, the current into the computer disconnected, to prevent problems with the car battery if you forget to turn off the computer when to turn off the car.

Enhancements

The use of the car computer as a medium of entertainment can be done easily. With a hard drive capacity is large enough, we can store thousands of songs in MP3 format. We can also play MP3, Audio CD, VCD, or DVD. With TV Tunner that plugs into a USB slot, we can enjoy television broadcasts. It should be added also a TV antenna on the roof of the car.

The computer can also be aandal navigational aids, by adding GPS receivers (with the USB port or serial port). Do not forget to install a navigation app such as Ozi Explorer, and enter the required map.

For certain areas, such as Jakarta which already has detailed maps, navigation system accuracy is quite high. For other areas, especially outside the city, province map to select a reliable intercity roads.

In this 2005 Honda CRV, enhancements installed system 2.4 GHz Wi-Fi network, using a Mikrotik Routerboard RB112 production, which is equipped with two wireless interfaces. One is connected to a WiFi antenna on the roof, and another uses an internal antenna. RB112 devices are small enough size (14 cm x 8.5 cm) can be installed in the jack storage box at the rear of the car.

In addition to the wireless device, network RB112 has many features, such as being a router, gateway or hotspot. If the car is in the WiFi service coverage, RB112 can serve as a gateway and forwards the car computer to access the Internet, and other laptops in the car.

If there is no WiFi access from the outside, the computer can access using GPRS or CDMA, RB112 can organize and distribute connectivity to other laptops and the area around the car.

Each person may have different options for the development of the computer. Many features can be installed on the car computer, along with a lot of devices use USB functions, and ultimately improve our productivity, because when driving though, there is a computer station next to us who are ready to help.

A brief review of the Micro AP (MAP-2n)

A brief review of the Micro AP (MAP-2n)

At the end of February 2014 MUM Italy ago, MikroTik introduces several new products, and we are lucky one of them was brought to Indonesia by the - by. An indoor smallest wireless router products with comprehensive features typical RouterOS. Let's welcome the new arrivals in Mikrotik, with the name of a Micro AP (MAP-2n). Comes with a small enough size and stylish design. Equipped with LED indicator.

Designed with a small form factor, but with the hardware specification is qualified as a wireless router in its class. It could also function as a mobile Router / Access Point. Here means the mobile router can be moved - moved because berfisat flexible. However, although the shape is quite small, with RouterOS Level 4 license that is drilled into the router, the MAP-2n able to meet your networking needs. Equipped with a similar processor and RAM makes the RB750-2n MAP suitable for personal / home / SOHO routers. Both software and hardware, existing features can be found on the MAP-2n. For example PoE-In, USB Port, PoE-Out, bandiwdth management, firewalls and so on. Has two ethernet ports and a built-in wireless complete with an internal antenna, so it can be used for the distribution of cable and wireless. We try to compare the size of folders - 2n with RB750.

Poe and the Poe-In-Out
MAP-2n has a function on ether1-in PoE and PoE-Out on ether2 that could provide power to other devices. Poe-In means the router can receive power through the network cable (UTP), so without the need for a power jack directly plugged into the router. This will make it easier when the router is placed in a location away from the power jack. Poe-Out on ether2 serves to provide power to other devices as well via UTP cable.

Micro USB

MAP-2n has a Micro USB port which can have a variety of functions. One function that is quite unique, not only for the MicroUSB Modem / storage alone, but on the MAP-2n can use this port provides power to the Router. We tried connecting the laptop MAP-2n, 2n-MAP and the results can be lit with the power from the USB port.

Of course this will make the MAP-2n more flexible, do not have to use a 220v power source, simply use a laptop or POWERBANK course, the router was able to walk.

In addition they can be used to receive power, micro USB can also be used should the USB port on the router proxy, such as for additional storage, and even a USB modem to dial. Here's a screenshot of our experiments using the CDMA modem. Dial using PPP features, and the internet from a modem can be shared by the MAP.

Embedded Wireless

This wireless router also qualified for the small-scale wireless networks, similar to the built-in wireless on the RB951-2n. The results of our experiment with making folders as an access point in an outdoor location without a hitch, the signal can be effective up to a distance of 20-30 meters. Built-in wireless and antenna on MAP-2n that support wireless N router makes wireless mini is getting interesting.

Unfortunately, MikroTik.com not provide certainty when this product will be distributed. So is the price range. Hopefully, mid or late 2014 release.

Features Logging In Mikrotik

Features Logging In Mikrotik

One feature that is visible on his Mikrotik simple and probably also forgotten but have a fairly important function is LOGGING feature.
RouterOS is able to perform a variety of recording information system events and status of the router.

By default RouterOS will keep records of all activities and processes that occur in the router and keeps a record (log) of the RAM. List of record (log) can be seen on the menu / log.
Logs are located in menu / logs will be lost once we restart the router because the log is stored only in RAM.

Examples of the appearance of the menus / log via Winbox.

In network troubleshooting will be more effective by analyzing the logs of the Router prior to knowing what the process is already happening. So it will be easier to map the problem and determine a solution.

Too much information that we get if we just look at the menu / log, so it may be difficult for analysis. For that we can make the topic of what will be recorded and will be stored or displayed where the log.

Besides stored in memory (RAM) routers, logs can also be stored as a file on the storage router, sent via email or syslog server is displayed on the device itself.

This setting can be done in the menu / system logging.

If you notice there are two tabs in the menu / system logging, the Rules Tab and Tab Action.

Tab Action (/ system logging action)
Used for setting the log storage methods.
There are 5 Type of Action that we can use:


1. The Disk Type
With this type of logs will be stored as text files and are saved in the system storage router itself. We can always set the current log file name is stored in the File Name parameter. Can also set how many lines of the log file that is stored in each of his, could set the parameters of Lines per file.

The log file can then be downloaded from the Files menu router and can be opened with a text editor on your PC

2. Type Echo
By using this type of router log will be displayed at the New Terminal (Winbox) or when we use the remote CLI (direct console)

3. Type email
Logs will be sent to the email that we have set. In order to function then we have to do before setting smtp server that will be used in the menu / tool e-mail

How often will the same as the email delivery Router how often the update log. Our advice, do not use public email services (like Yahoo or Gmail) because when sending emails too often public email services usually will consider it as spam.

4. The Memory Type
Logs will be stored in RAM Routers and can take a look at the log menu. Because only the logs are stored in RAM will be lost / can not read anymore after rebooting the router.

5. Type Remote
Logs will be sent to any device that runs the syslog server. We live designate the machine running the syslog server by entering the IP address.

If action has been created the next step we have to create a log rules.

Rules tab (/ system logging rules)
On the tab this rule we can make the topic or what services will we noted in the log. So that we can observe a process or service is more specific.

There are many services in our router and the new rules is that we make, we can specify one or more topic that we will record in the log.

The following example we will record all webproxy process is simple (! Debug).

Topic! Debug is optional. This means that no topic! Debug logging webproxy will also keep running. ! Debug log is used to keep the display is not too detailed. By default if we specify a logging topic, there is a process of detailed information that occurs on a machine that sometimes even confusing.

Example when logging topic WebProxy (! Debug) with remote action so that the log will be sent to the machine (PC) that runs the syslog server (172.16.1.254) with a simple syslog application of Mikrotik for Windows named MTSyslog.

The following figure shows the log display is seen at the application MTSyslog
MTSyslog application can be downloaded free of charge here .


By using this logging function we do not need to observe the processes that occur on the router continuously at all times. We simply view the results of the record (log) of existing processes to see what is going on as long as you do not observe the router directly.
