To insert a CompactFlash card, follow these instructions. 1. Disconnect the DA-685 from its power source. 2.
DA-683 Series Hardware Installation Installing a SATA Storage Drive The DA-685 embedded computer features a single SATA connector for SATA storage drives. To install a 2.5-inch SATA storage drive (SSD or HDD) a DA-685 storage drive mounting assembly must be acquired (it is not included in the basic DA-695 packaging).
DA-683 Series Hardware Installation 6. Connect the power cable and SATA cable to the motherboard, as follows: ATTENTION The SATA storage drive mounting assembly – which includes the SATA data and power cables – does not ship with the basic models of the DA-685 embedded computer. For purchasing information, please contact Moxa. Upgrading a DOM The DA-685 comes with an IDE-based DOM in which the operating system has been installed.
BIOS Setup This chapter describes the BIOS settings of the DA-685 computer. The BIOS is a set of input/output control routines for peripherals. The BIOS is used to initialize basic peripherals and loads the operating system. The BIOS setup allows the user to modify the system configurations of these basic input/output peripherals. All of the configurations will be stored in the NVRAM (flash memory), which retains the system information after system reboots or the power is removed.
