The ISA BUS signals are not used from the COM-1460. The only function of the ISA connector is the “passing-through” of the signals, and giving compatibility to the stack assembly. Below is shown a picture of the ISA BUS J1 J2 Figure 4. ISA BUS layout According to PC/104 specifications: “Key” locations - consisting of plugged holes in the upper side and omitted pins in the lower side - have been designated on each bus connector (on J1 and J2), to help assure proper connector mating.” The PCI BUS Connector J3 carries signals of the PCI Bus. The PCI Bus mechanical interface is a stackable 30x4 header. This interface carries all of the required PCI signals per PCI Local Bus Specification Version. 2.1. In the following page is shown a picture of the PCI BUS J3 PCI BUS Figure 5. PCI BUS layout For further information about the ISA bus and the PCI bus please refer to Eurotech web site (http://www.eurotech.it/) in the section Industry Standards. How to connect the COM-1460 to other PC/104 & PC/104-Plus devices: the stack assembly The ISA Bus connectors of the module are designed to allow the connection onto a stack of other PC/104 and/or PC/104-Plus devices. We recommend you follow the procedure described below to ensure that stacking of the modules does not damage connectors or electronic parts. 16 PC/104-Plus – COM-1460 Module 1. Turn off power to the PC/104-Plus system or stack. 2. Select and install standoffs to properly position the module on the PC/104-Plus stack. 3. Touch a grounded metal part of the rack to discharge any buildup of static electricity. 4. Remove the module from its anti-static bag. 5. Check that keying pins in the bus connector are properly positioned. 6. Check the stacking order; make sure an XT bus card will not be placed between two AT bus cards or it will interrupt the bus’s signals. 7. Hold the module by its edges and orient it so that the bus connector pins line up with the matching connector on the stack. 8. Press the module evenly onto the PC/104-Plus stack. 9. Verify that all the connections are properly made 10. Switch on the power If standard PC/104 modules are used in the stack, they must be the top module(s) because they will normally not include the PCI bus. The following picture shows an example of a module stack with 2 PC/104-Plus modules, 1 PC/104 16-BIT module, and 1 PC/104 8-BIT module. The maximum number of PC/104-Plus modules is 4 plus the (PC/104-Plus compliant) CPU board. If standard PC/104 modules are used in the stack, they must be the top module(s) because they will normally not include the PCI bus. If the CPU is PC/104 compliant you can only stack PC/104 modules and use only the ISA buses on the Backplane. If the CPU is PC/104-Plus compliant you can stack both PC/104 and PC/104Plus modules and use both PCI and ISA buses on the Backplane. Stackthrough 8-bit module 0.435 in. (11 mm) 0.6 in.

P PCI PCI (Peripheral Component Interconnect) is a standard high-performance, 32-bit / 64-bit bus, designed to be used with devices that have high bandwidth requirements. PCMCIA PCMCIA (Personal Computer Memory Card International Association). Sometimes used to refer to a controller for a type of expansion card documented in the PCMCIA standards. PIO The Programmed Input/Output is a method of transferring data over the IDE interface. The other way is the Direct Memory Access (DMA) PC/104-Plus – COM-1460 Module 35 R RAM RAM (Random Access Memory). Semiconductor-based memory that can be read-from and written-to by the microprocessor or other hardware devices. ROM ROM stands for Read Only Memory. This memory can only be read-from but not written-to. S SCSI SCSI stands for Small Computer System Interface. It is an I/O bus designed as a method for connecting several classes of peripherals to a host system without requiring modifications to generic hardware and software. SECAM SECAM (Sequential Couleur a Memoire; Sequential Colour with Memory). The television standard for France, Russia, and most of Eastern Europe. As with PAL, SECAM is based on a 50-Hz power system, but it uses a different encoding process and displays 819 horizontal lines per frame at a scan rate of 25 frames per second (50 fields per second). See also NTSC and PAL format. SMBus SMBus (System Management Bus). A two-wire interface based on the I²C protocol. The SMBus is a lowspeed bus that provides positive addressing for devices, as well as bus arbitration. SSD SSD stands for Solid State Disk (i.e. Disk on Chip, Disk on Module, Flash ROM,). In fact this is not a real disk but a silicon support memory without mechanical parts that are in movement. U UART UART (Universal Asynchronous Receiver/Transmitter), is a module composed of a circuit that contains both the receiving and transmitting circuits required for asynchronous serial communication. USB USB (Universal Serial Bus) is a 4-pin bi-directional, isochronous, dynamically attachable serial peripheral bus that is capable of cascading low/medium speed peripherals (less than 10 Mbit/s) V VGA VGA Video graphics array. A video adapter that supports 640 × 480-pixel colour resolution. A video display standard for boot devices under Windows operating systems. W WAN WAN stands for a wide-area network and it is a system of LANs (in geographically separated areas) connected together via telephone lines and/or radio waves.
