7 1. Introduction igure 1.1 The Stevens SatComm GOES CS2 Transmitter 1.1 GENERAL DESCRIPTION The Stevens SatComm Transmitter is a fully GOES Ver 2.0 compliant 300/1200 baud transmitter designed for remote applications. It performs as a satellite modem, collecting data from a data logger or other similar serial data output device for packetization and transmission over the GOES satellite system. It is capable of random and/or self-timed transmissions, at any combination of 300/1200 baud rates. Key features of the Stevens SatComm Transmitter are: GPS Disciplined TCXO frequency reference allowing for faster unit stabilization and lower current consumption. Unconditional frequency stability based on the GPS 1pps. Accurate Time Keeping based on the GPS 1pps. Digital synthesizer for transmission filtering and modulation. USB interface to external laptop. Self diagnostic capability. High output power (10W) capability. Echoing of logger data (internal or external) to the DCP Command Port for dual telemetry

8 1. Introduction 1.2. BASIC PRINCIPLES O OPERATION The Stevens SatComm (SatComm) and SatComm with Data Logger can be communicated with via a standard serial db9 port or a USB-type B connection and is setup using either a terminal emulation program (like HyperTerm) or using the included setup application SatCommSet. SatCommSet is a windows based GUI (graphical user interface). Using the terminal program (like HyperTerm, Termite, RealTerm, etc.) the user operates in two standard modes, off-line mode and On-line mode. Off-Line mode is the default mode upon power up and is the starting place for setting up the unit for operation. On-line mode can be entered from Off-Line mode by selecting Go to On Line Mode from the Off-Line Menu. All necessary setup information can be entered through the Off-Line Menu structure using the terminal emulation program on a PC. The application SatCommSet can also be used to enter all setup information. Once a unit is programmed, it can be placed On-Line and connected to the particular data logger to be used. If continuous self-timed message buffering is enabled, all serial transmissions received from the data logger will be placed in a buffer awaiting transmission at the next self-timed interval. A serial transmission beginning with the sequence ++R (default character sequence), will be placed in the random transmission buffer and will trigger the random transmission mode. The data in the buffer will not include the ++R characters. Data will be buffered for up to 120 seconds (user selectable), or until the receipt of ++E (default character sequence), indicating the end of the random data stream. This end sequence would also not be included in the random message. In random transmission mode, the unit will transmit a message as soon as is allowable, determined by unit warm up and transmission preparation requirements. Once a random transmission has been sent, additional transmission will be sent at the programmed random time interval. The number of repeat transmissions is also programmed. Standard transmissions will take priority, but will not be included as a transmission in figuring the random transmission count. The random transmission maximum length is fixed at 3.0 seconds for 300 baud and 1.5 seconds for 1200 baud. Longer data packets received from the data logger will be truncated. Self-timed transmissions will begin at the exact time programmed as the start time for transmissions. There is no option for window centering. Transmission time will be limited by user during the setup process. Longer data streams received from the attached data logger will be truncated. The maximum message window shall be 107 seconds, or a length of 3978 bytes. If continuous self-timed message buffering is not enabled, the SatComm will turn on the CTS line 1-60 seconds (user selectable) before it is time to transmit the message. This is done to wake up the data logger and give it enough time to transmit the data for the next message to the SatComm. The number of seconds can be adjusted. Setting the CTS time to zero will enable continuous standard data buffering, and any data received by the logger when in Online mode, which is not otherwise designated as a random message, will be put into the standard message buffer for transmission as a standard, timed message. All transmissions will require a set unit warm up time to allow for the SatComm to reach frequency stabilization. This is set to approximately 2 minutes, 40 seconds. At the same time

9 1. Introduction as the SatComm warm-up begins, the unit will wait for the GPS receiver to give a time and date fix. After an initial GPS lock, if a valid GPS time and date fix is not obtained before the transmission time, the transmission will continue. If a GPS update has not been obtained for 24 hours, self-timed transmissions will be inhibited. R power output is fixed depending on user entry of the baud rate and antenna type. Default value for 300 baud using a 10dBi antenna is 1.0 watts. It is not adjustable by the user. Note: Either random or self-timed messages, or both, can be enabled. One or the other must be enabled for the unit to enter the On-Line Mode. 1.3 SAETY INORMATION Before performing any procedures in this manual, please read all applicable warnings and cautions in the preceding section. Power sources, including batteries, can be a particular hazard to the user

22 3. Quick Start Remember that Date and Time are to be in UTC format (GMT or Zulu time), not local time. Under normal operation, the unit will obtain a GPS update prior to each transmission. If no GPS update is obtained for 24 hours, time scheduled transmissions will be prohibited until a good GPS update is achieved Check the system voltage by using the Display System Status menu. Select 4, Display SATCOMM Hardware and Software Status, followed by 2, Battery Voltage. This value should be in the range of 10.5 to 16 volts for battery or power supply operation. or a rechargeable lead-acid type, replace the battery when the indicated voltage drops below 11.0 volts, as there is very little useful energy remaining Check the transmitter output VSWR by using the Display System Status menu (from the Off Line Menu). Select 4, Display SATCOMM Hardware and Software Status, followed by 7, VSWR Measurement. This will return a value; VSWR = XXX.XX. A value of 002:00 or less is typical (this represents a VSWR of 2:1). Note: If a value of or above is measured, SatComm will inhibit the transmission If the SatComm is operated in a humid or condensing environment, place a fresh bag or two of desiccant together with the instrument inside of the NEMA-4 enclosure being used. Replace and recharge the desiccant on a regular basis. 3.3 STATION LOG We recommended that a station log be maintained for each field site, for future reference. Record such useful information as: Installation date for system battery. Transmit interval, transmit time offset, and assigned NESDIS ID and channel. System voltage, to establish a history for battery usage. VSWR measurement, to monitor the health of the output connection to the R cable and antenna. Other pertinent environmental or station operation data

24 4.1 INTRODUCTION The USB Port Interface permits connecting the SatComm to a computer or other serial communications device that uses USB and has a terminal emulation program. The purpose of this USB port is for setup and diagnostics through the menu commands. These same commands may be entered through the external Touch Screen interface connector. However, if both ports are connected, the USB port has the priority. Data to be transmitted is transferred through the External Logger DB9 serial port, as previously outlined in Section 3 (unless the Internal Logger version of the product is being used). In the following discussion, Section 4.2 describes the physical connections of the External Logger port along with the other two DB9 serial ports DCP Command Receiver and Touch Screen, as well as GPS Antenna. Section 4.3 provides a detailed description of the serial commands for setup and diagnostics. 4.2 CONNECTIONS The connections and signal definitions for the DB9 front panel Serial Port connectors are described in Tables 4.1, 4.2 and 4.3 below.

The SatComm USB driver will automatically install and assign a virtual COMM port on your computer. When using the Hyperterm or other terminal emulation program, you must select this virtual COMM port when setting up communication with the SatComm. Connection to the other DB9 connectors for External Logger, Touch Screen or DCP Command Receiver is made via a standard 9-pin serial cable. These accessories should be included in the purchase of your Stevens SatComm unit as requested for your DCP system

26 Note: Connection to the External Logger via a straight RS232 cable or a null-modem RS232 cable will depend on the configuration of the external data logger used with the SatComm. or use with the Stevens DL3000 data logger, a straight male-female RS232 can be used. Warning: PIN 9 O THE TOUCH SCREEN PORT IS DIRECTLY CONNECTED TO THE SYSTEM POWER SOURCE (E.G. +12VDC BATTERY). THE STEVENS EXTERNAL TOUCH SCREEN COMPUTER CONNECTION USES THIS PIN OR POWERING THE TOUCH SCREEN DEVICE. SPECIAL CARE MUST BE TAKEN TO ENSURE THAT THIS PIN IS NOT CONNECTED TO AN EXTERNAL DEVICE THAT DOES NOT NEED THIS POWER SOURCE. STEVENS IS NOT LIABLE OR DAMAGE CAUSED BY THE MISUSE O THIS POWER PIN. Connect the supplied GPS antenna via the SMA-f connector on the front panel and position the antenna with the best possible view of the sky. If there are obstacles such as buildings or foliage that blocks view of the open sky, it may hamper the SatComm s ability to get a location/time fix, which will prevent transmission from occurring. Contact Stevens technical support if this is the case so that an alternative GPS antenna solution can be suggested
