User Guide CG2-SHANTY • CompactPCI GPS Receiver Short Description Whenever the global time (UTC) or the geographic position is needed in a CompactPCI® based application, the GPS receiver board CG2-SHANTY is a perfect choice. Often industrial computer systems need synchronization to a precise time standard. A solution to this problem would be any radio controlled clock. Unfortunately, most regions have their own local transmitter standards. Hence, for universal use (e.g.
CG2-SHANTY • CompactPCI GPS Receiver/Clock The CG2-SHANTY incorporates a highly integrated digital GPS receiver, which uses the SiRFstarII chipset and is accommodated on a miniature daughter board as an exchangeable mezzanine sub-assembly. The 12-channel architecture provides rapid TimeTo-First-Fix (TTFF) under all startup conditions. The receiver decodes and processes signals from all visible GPS satellites, thereby producing a highly accurate and robust navigation solution.

CG2-SHANTY • CompactPCI GPS Receiver/Clock Installing the Board Warning This procedure should be done only by qualified technical personnel. Disconnect the system from its power source before doing the procedures described here. Failure to disconnect power, or telecommunication links before you open the system or perform any procedures can result in personal injury or equipment damage.
CG2-SHANTY • CompactPCI GPS Receiver/Clock Jumper Configuration & Factory Defaults Before inserting the CG2-SHANTY into your CPCI enclosure, please control the settings of some jumper fields on the board. Typically, there are two jumpers that need adjustment. C Set the jumper JBAT.
CG2-SHANTY • CompactPCI GPS Receiver/Clock C The CG2-SHANTY can be used to synchronize external events with the UTC (Universal Time Coordinated). Two single row 3-pin headers (JUTC1 & JUTC3) are provided optional to route the time signal to the UART controller or directly to the INTP pin on the CompactPCI backplane (J1 D4).
CG2-SHANTY • CompactPCI GPS Receiver/Clock Removing the Board Warning This procedure should be done only by qualified technical personnel. Disconnect the system from its power source before doing the procedures described here. Failure to disconnect power, or telecommunication links before you open the system or perform any procedures can result in personal injury or equipment damage.
CG2-SHANTY • CompactPCI GPS Receiver/Clock EMC Recommendations In order to comply with the CE regulations for EMC, it is mandatory to observe the following rules: C The chassis or rack including other boards in use must comply entirely with CE C Close all board slots not in use with a blind front panel C Front panels must be fastened by built-in screws C Cover any unused front panel mounted connector with a shielding cap C External communications cable assemblies must be shielded (shield connected
CG2-SHANTY • CompactPCI GPS Receiver/Clock Replacement of the Battery When your system is turned off, a battery maintains the current time-of-day clock and the values in the GPS receiver modules CMOS RAM current. The battery allows for nominal 4750hrs data retention. For replacement, the old battery must be removed from its socket. Change it against the same type only (Panasonic CR2032 3V). Observe the cell polarization - the ‘+’ mark appears on top.
CG2-SHANTY • CompactPCI GPS Receiver/Clock Technical Reference GPS Receiver Module General Features The CG2-SHANTY is equipped with the Navman Jupiter GPS receiver module, a 12 parallel channel receiver engine. Each of these receivers continuously tracks all satellites in view and provides accurate satellite positioning data. The Jupiter module size is about 28 square centimeters and satisfies harsh industrial requirements. The Jupiter module decodes and processes signals from all visible GPS satellites.
CG2-SHANTY • CompactPCI GPS Receiver/Clock Serial Ports & Protocols The Jupiter module communicates with the host across its primary serial port. The bit rate is fixed to 4800bps, no parity, 8 data bits, 1 stop bit. Commands are passed to the module, which responds accordingly with results and status information. Due to the low data transfer rates, there is no hardwired handshake available. There are two choices for protocol selection. By default, the NMEA standard is selected on the Jupiter Module.
CG2-SHANTY • CompactPCI GPS Receiver/Clock Antenna Connector The Jupiter receiver is equipped with a SMB type miniature coaxial female connector as RF signal input from the antenna. The antenna cable therefore should provide a matching SMB plug. When ordering an antenna, be sure to have selected the SMB connector version, if the antenna cable is directly attached (there are several other common connector types on the market, e.g. SMA, TNC and OSX).
CG2-SHANTY • CompactPCI GPS Receiver/Clock Jupiter Module Socket The Jupiter receiver module fits into a dual row, 20-position, 2.0mm metric socket and is mechanically fixed by 4 screws . Socket1 1 +3.3V 1 1 2 +3.3V/+5V Antenna 2 +3.
CG2-SHANTY • CompactPCI GPS Receiver/Clock Jumper JUTC, Time Mark The CG2-SHANTY can be used to synchronize external events with the UTC (Universal Time Coordinated). The board generates two output signals, named utctmark and utc10kHz, which can be used for various purposes. Both signals are wired to the (optional) 3-pin header connector JUTC. JUTC2 1Hz TMARK 10kHz 1 GND 3 (Optional) This connector is located near the Lithium cell.

CG2-SHANTY • CompactPCI GPS Receiver/Clock Serial Interfaces General Information The CG2-SHANTY is provided with two serial interfaces. The first one is directly connected to the NMEA (primary port) of the Jupiter GPS receiver. Commands and data are passed bidirectionally across this interface, either ASCII coded using the NMEA protocol (by default), or using the SiRF binary (proprietary) protocol.

CG2-SHANTY • CompactPCI GPS Receiver/Clock CompactPCI® Interface The CG2-SHANTY offers a CompactPCI® interface complying to the CompactPCI® Specification Revision 2.1. CompactPCI® is an industrial implementation of the familiar Peripheral Component Interconnect (PCI) bus. It combines the well known electrical features of PCI with the more robust mechanical 19 inch rack mounting technology. The interface supports 64-bit address and 32-bit data transfers.
CG2-SHANTY • CompactPCI GPS Receiver/Clock System Connector J1 The CompactPCI® specification defines the usage of shielded, 2 mm-pitch, 5-row connectors on CompactPCI® boards according to IEC 917 and IEC 1076-4-101. The 32-bit PCI interface is implemented via the J1 connector, while the 64-bit option requires the connector J2. Since the CG2-SHANTY has a 32-bit CompactPCI® interface, the J2 connector is not necessary and thus not mounted. The J1 connector also defines the supported signaling voltage (VI/O).
