The 5V Standby Problem: One of most difficult tasks of operating a PC in a vehicle is power consumption while the computer is OFF. Even if your computer is totally OFF, it will still consume about 100mA on the 5V rail. All power supplies have 5VSB (5Vstandby) mode so that they can issue at least a PSON signal. When the computer is in the suspend mode, it will consume even more power, because the RAM needs to be powered at all times. The power consumption in the suspend mode is few watts.No matter how big your battery is, it will eventually drain your battery in a matter of days.The M1-ATX is addressing these issues by cutting off the 5VSb rail after a pre-defined amount of time (see jumper chart). When 5Vsb is always active (HARDOFF=Never), M1-ATX watches the battery level. When battery level drops below 11V for more than one minute, M1-ATX will shut down and re-activate only when the input voltage is > 11V.Engine Cranks, under-voltage and over-voltage situations. Another very difficult task is maintaining stable 3.3, 5, 12 and -12V power to your PC. While car batteries are rated at 12V, they actually can provide voltages in between 7V (during engine cranks) or as high as hundreds of volts (load dump conditions). Most of the times, your battery will stay at 13.5V (while car is running) or 12V (when car is off), but extra precautions need to take place in order to prevent under and over-voltage situations. M1-ATX can operate as low as 5.7V and as high as 26V while providing strict regulation on all rails with input voltage clamping and reverse protection.Loud amplifier pops when PC starts. If your PC is connected to your car amplifier, you will hear a loud pop when the computer is first started. The M1-ATX has an #anti-thump# control that will keep your amp OFF while the PC starts. Simply connect J2 to your amplifier remote control pins to activate the #anti-thump# feature.2.0 Mode of operationThe M1-ATX performs several timing routines and takes actions as follows:(NOTE: When all config jumpers are removed, M1-ATX will be in the dumb PSU mode, no ignition timing, no HARDOFF. M1-ATX will send a gratuitous ON signal to the M/B when power is applied for the first time. Do not connect J8/J6 to the M/B on/off switch if you don#t want your PC to be started automatically) Saber más

The 5V Standby Problem: One of most difficult tasks of operating a PC in a vehicle is power consumption while the computer is OFF. Even when your computer is OFF, it willstill consume about 100mA on the 5V rail. All power supplies provide 5VSB (5V standby) so that the motherboard can issue at least a PSON signal. When the computer is in thesuspend mode, it will consume even more power, because the RAM needs to be powered at all times.No matter how big your battery is, it will eventually drain your battery in a matter of days.The M2-ATX is addressing these issues by cutting off the 5VSB rail after a pre-definedamount of time (see jumper chart, HARDOFF). When 5VSB is always active (HARDOFF=Never), M2-ATX constantly monitors the battery levels. When battery leveldrops below 11V for more than one minute, M2-ATX will shut down and re-activate only when the input voltage is > 11V.Engine Cranks, under-voltage and over-voltage situations. Another difficult task is maintaining stable 3.3V, 5V, 12V and -12V power to your PC. While car batteries arerated at 12V, they actually provide voltages in between 7-11V (engine cranks) or as high as 80 volts (load dump). Most of the times, your battery will stay at 13.5V (while car isrunning) but extra precautions need to take place in order to prevent such situations. M2-ATX can operate as low as 6V and as high as 28V while providing strict regulation on allrails along with input voltage clamping and reverse protection.Loud amplifier pops when PC starts. If your PC is connected to your car amplifier, you will hear a loud pop when the computer is first started. The M2-ATX has an #anti-thump#control that will keep your amp OFF while the PC starts. Simply connect J6 to your amplifier remote control pins to activate the #anti-thump# feature.2.0 Mode of operationThe M2-ATX performs several timing routines and takes actions as follows:(NOTE: When all config jumpers are removed, M2-ATX will be in the dumb PSU mode, no ignition timing, no HARDOFF. M2-ATX will send a gratuitous ON pulse to the M/B when power is applied for the first time. Do not connect J8/J9 to the M/B on/off switch if you don#t want your PC to be started automatically.
