Perhaps you live in a rural area and you can’t get cable or DSL high-speed Internet access, but you can get satellite. Or, maybe you are at your wit’s end with the cable and/or phone (DSL) companies and don’t want to give either of them another dime. Satellite may be the answer, but you’ll need to do a bit of research before determining if it will fit your needs. Here are answers to many of the most common questions regarding satellite service.Q: How fast is satellite access?A: Satellite providers typically offer several levels of service with download speeds ranging between 700 Kbps and 1.5 Mbps and upload speeds as high as 256 Kbps. Note, though, that these are optimal speeds. Typical speeds, particularly during peak times, can be somewhat slower.Q: How much does satellite access cost?A: The price depends on your provider and the service plan that you acquire. As a generalization, prices range from approximately $60 a month for service providing roughly 700 Kbps download speed to about $80 a month for service in the 1.5 Mbps range. In addition, your equipment costs can be as much as $300 or $400 and installation can cost another $200, although vendors often have special offers for equipment and installation.Q: What impact can weather have on satellite access?A: As is the case with satellite television, severe rain or snow can slow or stop satellite Internet access. That is true both for bad weather in your area as well as bad weather at the location of the satellite provider’s network operations center (NOC). However, while severe weather can break the connection, satellite systems typically operate even in strong, steady downpours.Q: Besides the weather, how reliable is satellite access?A: Besides service degradation due to weather, satellite

Locally or remotely control one or more computers with the help of the IP KVM Switch. These switches eliminate the distance limitations and allow multiple computers to be controlled remotely across a wide area network or local area network using TCP/IP protocols. They allow access and control of remote servers directly from the switch or any other location via web browser.These devices are compatible with every OS platform and network device in the office environment. They are available in either 8, 16 or 32 ports and can be cascaded for connection to up to 128 servers. Push buttons on the front panel, OSD menu or a combination of hot keys are used to control them. The main feature of KVM over IP is that it adds greater flexibility to the network and provides high performance along with taking care of security management. It also has the ability to automatically sense video resolution for best screen capture. Since the software which enables remote monitoring and controlling runs on its embedded processors and not on mission critical servers, it does not interfere with operation of servers or the functioning of the network. This device also has a built-in microprocessor emulation for each port boot up process and a BIOS level access for administration.This device is designed keeping in mind the characteristics of the traditional KVM Switches so that it can provide added benefits over them. The KVM over IP switch works on the plug and play technology and does not require any software to be installed on the servers or remote PCs. Another characteristic of this device is the availability of scan mode to monitor servers at intervals between 5 and 99 seconds. It also has a multilingual interface allowing users to select English

Having a hard time designing your tester?Designing and conceptualizing an ATE is not an easy task.Here are some points and steps you may consider in designing your own automated test equipment (ATE) that will fit your needs.Test Coverage:List down all the existing power supply, newly develop power supply and the future projects with the following needed information:• Input Power requirement: for input source, you have to plan what input source you may need to cover all input requirement for all the your product lines. • Output power requirement: number of loads you need to consider, this will range from the high power range to low power range. • Number of outputs and signals: this is very critical since you have to plan for the standard mux allocation. For this, more mux allocation the better. • Control switches: review each test requirement for each of the product for all the test that requires relay or switches. You have to be very careful in planning this out. This will be use on how many general purpose switches or relay you will install in your ATE. You can check also new test methodology that might be possible test for the new products.From the list, you should accomplish the following information:• You will have an idea on what input source your going to use to cover all power supply you’re about to test. • You will have an idea on how many load modules you need to install to cover high power multiple outputs power supplies. You will also need to add low current load module for lower current outputs. • You will have idea on how many muxes and switches your going to use.Test Interface PanelYou need to consider the test interface your going to… Continue reading
