I/O SERVER User’s Manual Industrial PC __________________________________________________________________ 2.0 PREPARATION FOR USE UNPACKING AND INSPECTION Upon receipt of this product, inspect the shipping carton for evidence of mishandling during transit. If the shipping carton is badly damaged or water stained, request that the carrier's agent be present when the carton is opened.
I/O SERVER User’s Manual Industrial PC ___________________________________________________________________ To install the IOS modules, first remove all power from the device. The IOS Carrier is not hot swappable. Failure to power down the I/O Server prior to removing the IOS carrier will result in board damage. To remove the IOS Carrier turn the two Captive screws counterclockwise on the front panel until they are free of the enclosure. Then pull the IOS Carrier out from the enclosure.
I/O SERVER User’s Manual Industrial PC __________________________________________________________________ Figure 2.2b: IOS Module Installation To install the IOS Modules firmly press them into any of the four available slots. IOS Modules are keyed to avoid incorrect installation. Note: Inserting the IOS Carrier may require considerable force. After IOS module installation, slide the IOS Carrier back into the enclosure via the guide rails until the front panel is flush against the faceplate.

I/O SERVER User’s Manual Industrial PC __________________________________________________________________ 4.0 SYSTEM OVERVIEW WARNING: Per specifications, only the USB ports are switchable while power is applied to the system. I/O Server Internal Ethernet Switch This Section provides information regarding system design and operating information for the I/O Server. Reference the block diagram below as you read this material. The I/O Server has an embedded Intel N270 1.6GHz CPU.
I/O SERVER User’s Manual Industrial PC ___________________________________________________________________ 29 degradation of the I/O Server environmental specifications, Acromag recommends use of a Solid State (Flash) 2.5” Hard drive. These drives are available from manufacturers such as Transcend or SanDisk and have no mechanical parts. Consequently they have superior shock and vibration and temperature specifications when compared to conventional hard drives.
I/O SERVER User’s Manual Industrial PC __________________________________________________________________ IOS Logic Interface The IOS logic interface is also implemented in the carrier board’s FPGA. The PCI bus address and data lines are linked to the address and data of the IOS logic interface. The PCI bus to IOS logic interface link allows a PCI bus master to: • Access up to 64 ID Space bytes for IOS module identification via 8-bit or 16-bit data transfers using the PCI bus.
I/O SERVER User’s Manual Industrial PC ___________________________________________________________________ The IOS Carrier and subsequently the IOS modules must be accessed thought the PCI bus. The PCI bus is defined to address three distinct address spaces: I/O, memory, and configuration space. The IOS modules can be accessed via the PCI bus memory space only. 31 5.0 ACCESSING THE IOS CARRIER The IOS carrier is a Plug-and-Play PCI board.
I/O SERVER User’s Manual Industrial PC __________________________________________________________________ The Configuration Registers are accessed via the Configuration Address and Data Ports. The most important Configuration Registers are the Base Address Registers and the Interrupt Line Register, which must be read to determine the base address, assigned to the carrier board and the interrupt request line that goes active on a carrier interrupt request. Table 5.

I/O SERVER User’s Manual Industrial PC __________________________________________________________________ IOS Interrupt Pending Register - (Read, PCIBar2 + 02H) The IOS Interrupt Pending Register is used to individually identify pending IOS module interrupts or a pending carrier board generated interrupt as a result of IOS module time out access. If multiple IOS module interrupts are pending, software must determine the order in which they are serviced.
I/O SERVER User’s Manual Industrial PC ___________________________________________________________________ Each IOS module contains identification (ID) information that resides in the ID space. This area of memory contains at most 64 bytes of information. Both fixed and variable information may be present within the ID ROM. Variable information may include unique information required for the IOS module. The identification Section for each IOS module is located in the carrier board memory map per Table 5.3.
I/O SERVER User’s Manual Industrial PC __________________________________________________________________ 6.0 SERVICE AND REPAIR Surface-Mounted Technology (SMT) boards are generally difficult to repair. It is highly recommended that a non-functioning board be returned to Acromag for repair. The board can be easily damaged unless special SMT repair and service tools are used. Further, Acromag has automated test equipment that thoroughly checks the performance of each board.
