Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si Simply plug into the PCI or ISA slot and the computer hardware will be immediately tested for a full diagnostic test. Let faulty parts show you are in control. The purpose of a diagnostic card is to find computer hardware problems easily and quickly. It can help us in the computer failure more quickly and accurately find the problem of hardware, no matter you are development engineers, maintenance engineers or a beginner or a - user, as long as you have it, it can display computer hardware failure parts accurately, let you fast and correctly, the problem with computer problems. Installation :Insert the diagnostic card into the PCI or ISA slot on the computer motherboard. Turn on the according to the digital code displayed on the diagnostic card, against the distribution of the "operation manual" inside the code meaning table, is, ah know what part of the hardware is wrong, from now on no need to substitution on the display, graphics card, memory, CPU continuing-substitution can determine the faulty parts. Technical parameters: Bus interface: 32-bit standard PCI domain 8-bit ISA interface;Digital display: 7bit digital display, fault code display, two points display 5V and reset signal; Product description: 1.Motherboard diagnosis she is called POST card ( On Test) or PC analyzer, is to show the motherboard BIOS -check program code, with the specification of the POST code meaning can quickly know where the computer failure. In particular, the PC can not boot the operating system, black screen, the of the buzzer is more convenient, so you get twice the result with half the effort! So people who often install and repair computers are almost everyone must have this card. For desktop computers: (1) operating indicator light with main board; (2) the of elements will not hurt the hand; (3) this card can be inserted into ISA or PCI; (4) no part will be burned after the is switched on after the wrong slot is inserted or reversed; (5) the machine can display repeated automatic reset under the black screen; (6) without CPU and other empty board and can be diagnosed in the board Lamp: 1. -12 LED: -12v supply indication 2. +12 LED: +12V supply indication 3. CLK LED: CLK signal indication 4. OSC LED: OSC no. Indication 5.
