Module Setup
IMPORTANT NOTE!
The LM104-P50 module gets all of its electrical power through the PC/104 bus connector. The module requires +5Vdc, ±10% at 420mA. Because it was designed specifically for the PC/104 bus, the module does not support any external power supply, nor is it designed to run at any other supply voltage. Operating an LM104-P50 module at a supply voltage higher than +5Vdc will probably damage the module and will definitely void the warranty. A supply below 4.65Vdc will not damage the module, but it will not function, because the supervisory circuit will force the Neuron into RESET and hold it there.
Before installing the LM105-P50, check the host system for the availability of interrupt request lines (IRQs) and free I/O address locations. Most problems with configuring the LM104-P50 can be traced to conflicts between the LM104-P50 and some other device in the system. The software driver will work with any combination of I/O address and IRQ that is not shared with any other device. Note that more than one LM104-P50 may be installed in the same host system, provided each module has its own address and IRQ. Please see page 3 for jumper settings and page 5 for software driver installation details.
The LM105-P50 (Option 1/2/3/6) installs like any other PC/104 board. It has a 16-bit stackthrough connector, so other PC/104 boards may be installed above or below it in the stack, using 0.6” (15mm) spacers to maintain proper distance between cards. Note that Option 5/5C boards do not allow boards to be installed above them, as the Echelon PLT-22 transceiver is too tall. Option 5/5C boards must be installed at the top of a stack.
Before plugging the PC/104 boards together, double check to insure that the boards are aligned properly, and that the PC/104 connectors between boards are not off by one position.
