Page 24: Pc104 Bus
7.17. PC104 Bus The PC/104 bus is essentially identical to the ISA Bus except for the physical design. It specifies two pin and socket connectors for the bus signals. A 64-pin header J1 incorporates the 62-pin 8-bit bus connector signals, and a 40-pin header J2 incorporates the 36-pin 16-bit bus connector signals. -
Page 25: Pc/104 I/O Board Installation
PC/104 I/O Board Installation Samson supports a PC/104 (ISA bus) I/O expansion board in either 8-bit or 16-bit configuration. Each PC/104 board has its own address range. The lowest address of this range is called the base address. Most PC/104 boards will have information on how to select the base address. No two boards may overlap their address ranges, otherwise the system will not operate correctly. -
Page 26: Installation Steps
Installation Steps 1. Check that the PC/104 connectors are compatible. The PC/104 standard specifies two key pins on the connectors, numbered B10 and C19. On the top socket side, these pins should be plugged, and on the bottom side, they should be cut away. This helps to prevent misalignment during installation. Not all vendors adhere to both the plugged sockets and cut pins.
