lab. When I first joined the lab, I could ask my teacher or graduate students in the lab. but now they have never done can, and I have to do it myself. the teacher asked me to do this can because no one in the lab has done it before. All the medical instruments previously developed in the lab use 485 bus. The teacher saw the decline of 485, And the can could be dug up. So I want to switch to can. In fact, there are not many things on the hardware for my task. the main reason is that the softwa

A modem is a combination of a modulator and a demodulator that allows data to be transmitted over an analog signal transmission line. Through the modulation mediator can use the telephone line to achieve the computer data transmission and communication, of course, the general is to buy the cat alone to achieve dial-up Internet. The route light Cat is a transceiver that converts optical Ethernet signals into other protocol signals. The route Light cat

, filtering out the user caused "harassment" of the spam message. But after all, there is no guarantee that users will be completely protected. It's also certain that there are occasional miscalculations. Therefore, the default settings are not entirely easy to use, if you want to make Kaspersky's message protection capabilities more powerful, users also need to set up the Kaspersky software function, according to their actual needs, to adjust it.

a straight line. Use the crossover line to cascade the switch through the normal port. Cascade of Switch Fibre ports Because the price of the switch fibre port is still very expensive, the fiber is used primarily for connecting between the core switch and the backbone switch, or for cascading between the backbone switches. It should be noted that the switch fibre ports are not stacked and can only be used for cascading. Cross-connect of fiber jumper More Wonderful content: http://www.biance

changing as each symbol changes. EVM is also very important for the performance of WCDMA transmitter, because it indicates the modulation quality of the transmitting signal. A large EVM value will result in poor detection accuracy, thus reducing the performance of the transceiver. Frequency error: The difference between the specified carrier frequency and the actual carrier frequency. Due to the adjacent channel interference and low quality detecti

. Purchase the same brand and model of the receiver What if the wireless mouse receiver is lost? Everyone can first look at their own wireless mouse brand models, and then find the corresponding business information to see if there is a corresponding model of the receiver can be purchased separately. However, by consulting a number of stores, found that many brands of wireless mouse receiver is not supported by separate purchase, as shown in the following figure. Wireless mouse rec

Q: The use of optical mouse to think that the mouse is too flexible, when playing CS mouse pointer sometimes a little "drift", how to solve? A: This problem should be related to the Windows XP operating system's mouse pointer acceleration function. You can click the Start menu, select settings → control Panel, select Mouse, click the Pointer Options tab, tick the "Improve pointer accuracy" option, and then change the speed of the pointer to one that is appropriate for you. In addition, some bra

system uses six 10/100 BASE-TX ports and two 100BASE-FX ports. The six 10/100 BASE-TX ports need to be connected to the RJ-45 interface through the isolation transformer HR604009, which is an isolation transformer that provides 4-way RJ-45 interfaces. Two 100BASE-FX ports can be directly connected to the optical transceiver V23826, which provides a single-mode SC interface.
