  • Page 3: Description

    DC/DC Power Supply PC/104 Module With 2 Serial Ports 1. DESCRIPTION JUPITER-MM-SIO is a PC/104-format power supply module designed for mobile as well as stationary embedded applications. The JUPITER-MM-SIO design incorporates a high efficiency DC/DC converter circuit to provide power with minimum losses. Power supply performance and reliability have been optimized through the use of precision surface mount components.

  • Page 9: Serial Port Configuration

    Each peripheral board in the computer system must have a unique I/O address or block of addresses. The Jupiter-MM-SIO actually uses five I/O address blocks: one for each of the four serial ports and one for the interrupt status register. Each port’s address block consists of 8 consecutive addresses, while the interrupt status register occupies a single address.

  • Page 10: Configuration For Rs-422 And Rs-485 Modes

    This technique avoids contention by two devices trying to drive the same line with opposing logic levels. Jupiter-MM-SIO uses this technique for the two serial ports. To use the same interrupt level for both serial ports, install a jumper in the same number location for both ports and install a jumper in the R location for only one port.

  • Page 11: Interrupt Status Register

    On the Jupiter-MM-SIO, an RS-485 port’s transmitter enable signal is controlled by that port’s RTS signal. The RTS signal must be asserted (driven low) to enable the transmitter and deasserted (driven high) to turn off the transmitter.

    5. INSTALLATION All Jupiter-MM-SIO power supplies are load tested prior to shipping. The supplies ship with all the external connectors required to start using your supply immediately. Any connector not needed can be removed. 1. Select the serial port base addresses using J9. Refer to page 9 for instructions.

    6. OUTPUT VOLTAGES AND CURRENTS Jupiter-MM-SIO provides either 4 output voltages. The outputs appear on the PC/104 bus headers J1 / J2 as well as on the auxiliary I/O connector J5. The table below lists the maximum ratings for each output voltage.
