3. SAT ARGOS Configuration
The SAT ARGOS PTT must be configured before you deploy it. Service
Argos uses two numbers to track your data through the Service Argos system.
The first number is your Program ID; the second number is your Argos ID.
The PTT can use up to four Argos ID numbers. You must have your Argos ID
number before you can configure your PTT. The Argos ID number and
transmission repetition rate is written to the SAT ARGOS PTT during
configuration.
3.1 SAT ARGOS Power Supply
During configuration, the PTT is powered through the SC532A. For a power
supply the SC532A uses a 12 volt DC wall regulator/transformer or a direct
connection to a 12 volt battery. The SC532A has two internal jumpers.
Jumper P2 supplies 12 volts to pin 8 of the peripheral port. Jumper P4 (Mode)
changes the operational mode of the SC532A. In the “ PROG” or program
mode, the SC532A will provide the interface between a computer and the SAT
ARGOS. The SC532 mode is used for storage modules. When using the
SC532A to configure the SAT ARGOS transmitter, configure the jumper P4
for “ PROG” and jumper P2 for “ +12V on P8” .
The SC532 will not work in place of the SC532A.
3.2 Pttcomm.exe
Included with each SAT ARGOS is a 3.5 inch diskette. The information on the
diskette should be copied to a computer. Load the diskette in the floppy disk
drive and execute “ Setup.exe” .
The computer must have a working RS 232 port. Pttcomm.exe is a 32 bit
windows-based program. Run Pttcomm.exe; use “ File/Open” to open the
configuration file “ Argos.cfg” .
Edit your Argos ID number, or numbers, if you are using more than one.
Scroll down to “ Fast Transmission Rep Rate” and “ Slow Transmission Rep
Rate” . Enter the appropriate repetition rate for each field. Fast transmission
rep rate is the time between each burst of data transmission (up to 32 bytes
each). Slow rate only applies when using more than one Argos ID number.
Slow transmission rep rate is the time between each burst of data for each ID
number.
In most cases, “ Transmission On Time” and “ Transmission Off Time” will
not need to be changed. Transmission on time is the time the transmitter
continues to send bursts of data at the slow and fast transmission rep rates.
Transmission off time is the amount of time the PTT is shut down after the
transmission on time has been completed. Transmission on/off time starts
when the PTT is powered up.
