The SATPAK104GPS-25WATT is an advanced version of the popular SATPAK-104PLUS that also incorporates a 25 Watt DC-DC converter on the same PC/104 module. In many PC/104 applications, the addition of the 25 Watt DC-DC converter combined with the GPS function will eliminate a stack position that would otherwise require a dedicated PC/104 power supply module. This concept provides an inexpensive method to interface a GPS receiver to the PC/104 bus and provide power for the PC/104 bus and external peripherals. The SATPAK104GPS-25WATT can be configured to mate with either a Trimble SK2/SK8 (Lassen), Trimble ACEII/ACEIII, Trimble LassenLp, Navman Jupiter, Canadian Marconi Superstar II, Motorola GT/UT Oncore, or Motorola M12 GPS receiver. The TTL communication signals of the selected GPS receiver are transmitted and received over the PC/104 bus using a universal asynchronous receiver transmitter (UART). The GPS receiver interface can be selected for COM1, COM2, COM3, or COM4 base addresses via a simple push-on jumper. Custom addresses can be supported. The associated PC/104 bus interrupt can be selected from IRQ3-IRQ7, IRQ10-IRQ12, IRQ14, or IRQ15. A keep-alive voltage is generated by using a large value capacitor (0.22 Farad) to maintain the almanac, ephemeris, and real-time clock of the GPS receiver. A right angle 10-pin connector allows RS-232 communication to accommodate differential GPS (DGPS) corrections or secondary communication with some models of GPS (Trimble) receivers. The same connector also provides access to the 1PPS time pulse generated by the GPS receiver. The 25 watt DC-DC converter accepts voltage inputs from 8V to 40V and provides +5V as standard, and optional +12V, -12V, and -5V to power the PC/104 bus and external peripherals. The +5V output by the DC-DC converter is GPS compliant and satisfies the ripple requirements of all GPS receiver modules that can be used with the SATPAK104GPS-25WATT. The DC-DC converter is designed for vehicle applications and utilizes a heavy duty "Load Dump" transient suppressor (5000V) that clamps input transients to tolerable safe voltages. A low voltage AC input option is available. A pass-through connector (P2) allows connection to an optional battery pack module.
