Users Manual & Installation Guide PV- 5127: Power supply module with UPS PC/104 bus connector (CN1) The PC/104 connector is for connecting the PV-5127 to the CPU and other PC/104 boards. There is a female connector on the top, and pins on the bottom so that you can mount other PC/104 boards both above and below the PV-5127. The main +5V and +12V outputs are available in the PC/104 connector, so you don’t need to use the KL3 outputs when drawing smaller

Users Manual & Installation Guide PV- 5127: Power supply module with UPS System temperature The PV-5127 has a temperature measuring circuit that can control an external fan and heater, and prevent the CPU from starting if the temperature is too low or too high. It monitors the system temperature as long as +5V STB is on. As system temperature sensor, you can use the onboard sensor, or an external sensor of type Infineon KTY 11-5 connected to J2 (label

Users Manual & Installation Guide PV- 5127: Power supply module with UPS Note that the heater and fan outputs are logical outputs that become 3.3V when they are active. If necessary, the user must provide driving circuitry to drive an actual heater and fan. The positions of the two outputs in CN2 are shown here. If the temperature is too cold or too hot, the CPU cannot be turned on until it changes to cool or warm. But if it the CPU is on, and th

Users Manual & Installation Guide PV- 5127: Power supply module with UPS UPS Control The PV-5127 provides several methods for the CPU to get UPS status information, and to turn off power. The CPU can get status information through the RS232 and the PC/104 interface, and it can perform a software-controlled power-off through the ATX PS_ON signal, through an RS232 signal, and through the PC/104 interface. PS_ON signal Two of the ATX functions that are s

The PV-5127 provides two handshake outputs with status information, and one handshake input for controlling shutdown. The RxD and TxD signals are not used, the only used signals are Ground and the three handshake signals. The three signals are compatible with the “simple s

Users Manual & Installation Guide PV- 5127: Power supply module with UPS PC/104 interface The PV-5127 has a software interface where the CPU can read status information and perform a power-off through the PC/104 bus. The power-off can be delayed up to 253 seconds, so that the UPS monitoring can start the delayed power-off, then start a shutdown of the operating system, and the actual power-off happens after the operating system has finished shutting down.
