Hi Jean, I got a answer from Epox : Dear Age, Sorry for that due to the datesheed is confidential.So we can't share it to you. But we can share the register for you reference.That's all we can share to you. See attachment. Thank you for your interest in EPoX products and contacting our support department. If you reply ensure to include all previous E-mail text. It will prevent unnecessary delays and guarantee the fastest possible response. Best Regards, ================================================= Technical Support (AFA) EPoX Computer Co., LTD. (Head office) E-Mail : support at epox.com.tw Web : www.epox.com Please provide previous E-mail text if replying. Specifications subject to change without notice. ISA bridge index port 295h. ISA bridge data port 296h. Address Attribute Description ======================================================================================= 20h RO VCC3V reading. The unit of reading is 8mV. 21h RO V1(Vcore)reading. The unit of reading is 8mV. 22h RO V2 reading. The unit of reading is 8mV. 23h RO V3 reading. The unit of reading is 8mV. 24h RO V4 reading. The unit of reading is 8mV. 25h RO V5 reading. The unit of reading is 8mV. 26h RO V6 reading. The unit of reading is 8mV. 27h RO VSB3V reading. The unit of reading is 8mV. 28h RO VBAT reading. The unit of reading is 8mV. ======================================================================================= 72h RO Temperature 1 reading. The unit of reading is 1 degree C. At the moment of reading this reg. 74h RO Temperature 2 reading. The unit of reading is 1 degree C. At the moment of reading this reg. 76h RO Temperature 3 reading. The unit of reading is 1 degree C. At the moment of reading this reg. ======================================================================================= A0h RO FAN1 count reading(MSB). At the moment of reading this register, the LSB will be latched . This will prevent from data updating when reading. To read the fan count correctly, read MSB first and followed read the LSB. A1h RO FAN1 count reading(LSB). B0h RO FAN2 count reading(MSB). At the moment of reading this register, the LSB will be latched . This will prevent from data updating when reading. To read the fan count correctly, read MSB first and followed read the LSB. B1h RO FAN2 count reading(LSB). C0h RO FAN3 count reading(MSB). At the moment of reading this register, the LSB will be latched . This will prevent from data updating when reading. To read the fan count correctly, read MSB first and followed read the LSB. C1h RO FAN3 count reading(LSB). D0h RO FAN4 count reading(MSB). At the moment of reading this register, the LSB will be latched . This will prevent from data updating when reading. To read the fan count correctly, read MSB first and followed read the LSB. D1h RO FAN4 count reading(LSB). ======================================================================================= The formula is voltage divided formula as following below: VIN = V(+12V) * (R2 / (R1 + R2)) where V(+12V) is the analog input voltage. ======================================================================================= The formula is fan count / RPM calculated formula as following below: RPM = (1.5 * 10 ^ 6) / Count where ^ is the exponent symbol. ======================================================================================= Age Huisman
