1. This WDT comes with 8 possible ranges of time intervals from 500 ms to 64 sec which can be adjusted by setting jumper positions It could be enabled and programmed by reading I O port 0443H or 0433H to issue trigger continuously and disabled by reading I O port 0343H or 0033H A tolerance of 30 timer limit must be considered For instance if the time out interval is set to 1second the WDT trigger command must be issued within 700ms at least The below example gives you a reference algorithm for WDT programming via T O port 0433H and 0033H in your application program Enable WDT MOV DX 0433H IN AL DX Re trigger WDT MOV DX 0433H IN AL DX Disable WDT MOV DX 0033H IN AL DX ROBO 485 515 User s Manual 3 32. DRAM or SDRAM is 128MB The DIMM used could be either 3 3V EDO Extended Data Out memory with speed less than 70ns or 3 3V SDRAM Synchronized DRAM with speed less than 100ns ROBO 485 515 User s Manual 3 1 System Installation For system compatibility and stability don t use memory module without brand You can also use the single or double side DIMM without parity check and ECC function Watch out the contact and lock integrity of memory module with socket it will impact on the system reliability Follow normal procedure to install your DRAM module into memory socket Before locking make sure that the module has been fully inserted into card slot NOTE For maintaining system stability don t change any of DRAM parameters in BIOS setup to upgrade your system performance except for getting technical information 3 3 M system Flash Disk ROBO 485 515 reserves one 32 pin DIP sockets for installing M system Flash disk from 2MB to 144MB This operation structure is running with pure ISA bus without PnP Plug and Play function Before installing make certain that T O address jumper setting is set on right position to prevent unworkable system due to I O resource conflict Do remember to follow DOC Disk On Chip installation procedure Otherwise the Flash chip is possible to be burned out due to incorrect installation Installing DOC Align the DOC with pin holes on the socket Make sure that the notched corner or dot mark
3. System Installation CHAPTER 3 System Installation This chapter provides you with instructions on how to set up and configure your system The additional information shows you how to install M system Flash disk and handle WDT operation in software program 3 1 Socket 7 Processor Installing CPU 1 Lift the handling lever of CPU socket outwards and upwards to the other end 2 Align the processor pins with pin holes on the socket Make sure that the notched corner or dot mark pin 1 of the CPU corresponds to the socket s bevel end Then press the CPU gently until it fits into place If this operation is not easy or smooth don t do it forcibly You need to check and rebuild the CPU pin uniformity 3 Push down the lever to lock processor chip into the socket 4 Follow the installation guide of cooling fan or heat sink to mount it on CPU surface and lock it on the socket 7 5 Be sure to follow particular CPU speed and voltage type to adjust the jumper settings properly Removing CPU 1 Unlock the cooling fan first 2 Lift the lever of CPU socket outwards and upwards to the other end 3 Carefully lift up the existing CPU to remove it from the socket 4 Follow the steps of installing a CPU to change to another one or place handling bar to close the opened socket 3 2 Main Memory This ROBO 485 515 provides one DIMM 168 pin Dual In line Memory Module to support on board main memory The maximum memory size for 3 3V EDO
4. pin 1 of DOC corresponds to notched corner of the socket Then press the DOC gently until it fits into place If installation procedure is correct the Flash disk can be viewed as a normal hard disk to access read write data WARNING Please ensure that your DOC is properly inserted Placing the DOC in reverse will cause severe damage to it If you want to boot from this Flash disk it is necessary to refer to the application note from M system You can easily obtain relative information from M system shipping package such as product manual or Web site http www m sys com ROBO 485 515 User s Manual 3 2 System Installation 3 4 Installing the Single Board Computer To install your ROBO 485 515 into standard chassis or proprietary environment you need to perform the following Step Check all jumpers setting on proper position Step 2 Install and configure CPU and memory module on right position Step 3 Place ROBO 485 515 into the dedicated position in your system Step 4 Attach cables to existing peripheral devices and secure it 3 5 Watch Dog Timer Programming An optional two port Watch Dog Timer WDT is provided on ROBO 485 515 If this feature is enabled by jumper setting and software trigger a system reset will be generated unless the CPU triggers the timer periodically within time out period This allows the system to restart in an orderly way in case of any abnormal condition is found
