- Page 7 The SAT SCD/ARGOS PTT supports up to four Argos ID numbers and four SCD2 ID numbers. Message repeat intervals, ID numbers and duty cycles can be changed with a simple-to-use computer-based interface. The transmitter connects directly to the CS I/O port using the standard SC12 ribbon cable.
- Page 8 SAT SCD/ARGOS 1.1 Physical The SAT SCD/ARGOS PTT is housed in an aluminum enclosure measuring 3” x 2.75” x 1”. There are two electrical connections. The DB9 port connects to the datalogger CS I/O port. The SMA female port connects to the 50 ohm impedance antenna.

The Array ID is not sent. If you are writing a time stamp to final storage, don’t forget to include the time stamp as additional data points. The SAT SCD/ARGOS can hold up to four data packets. Each data packet is transmitted as a single message. High resolution data points are four bytes, but high resolution data are not supported by the P125 SAT SCD/ARGOS program instruction. - Page 10 SAT SCD/ARGOS When sending one data packet of 16 data points, the PTT will repeat the data packet at the repeat interval. When sending two data packets of 16 data points each, total of 32 data points, the PTT will alternate between each data packet.

SAT SCD/ARGOS 2.3.4 Using Result Codes in the Program After P125 has executed, check the result codes. If the result code is greater than or equal to two, execute P125 again. Recheck the result code on the next pass of the program table. Example Algorithm:... - Page 12 5: Sample (P70) 1: 13 Reps 2: 3 Loc [ Start_1 ] ; If top of the hour, transfer all new data to the SAT SCD/ARGOS transmitter 6: If time is (P92) 1: 0 Minutes (Seconds --) into a 2: 60...
- Page 13 SAT SCD/ARGOS 3. SAT SCD/ARGOS Configuration The SAT SCD/ARGOS PTT must be configured before you deploy it. Two numbers are used to track your data through the system. The first number is your Program ID, the second number is your SCD/Argos ID. The PTT can use up to 4 SCD numbers and up to 4 ARGOS ID numbers.
- Page 14 (SC12). Before you apply power, you should have a dummy load or antenna connected to the RF output of the SAT SCD/ARGOS. Do not apply power to the SAT SCD/ARGOS yet. Make the following connections: 1) PTT to SC532A using the SC12 ribbon cable.

SAT SCD/ARGOS over the poles 14 times a day providing 28 satellite passes per day. Coverage decreases with latitude. At the equator the PTT will “see” a satellite six or seven times a day. The SCD2 satellites are in a different orbit pattern than the POES satellites. - Page 16 SAT SCD/ARGOS...
