The TS-7800-V2 coincides with enhanced support for the TS-IRIDIUM SBD transceiver module. The TS-IRIDIUM SBD transceiver provides satellite data communication from anywhere in the world provided its antenna has a full, clear view of the sky.
The IRIDIUM satellite constellation consists of 66 low orbit satellites, moving from north to south. For best connectivity, the SBD antenna should have a clear view of approximately 95% of the open sky, or full sky visibility above 8.2 degrees from the horizon.
To check the height of potential obstructions, it is useful to hold a fist at arm's length with the wrist parallel to the horizon. Obstructions larger than that fist above the horizon could interfere with the Iridium signal. Cliffs, buildings, vehicles, and dense foliage will interfere with the satellite signal. Smoke, clouds, fog, rain, and weather will not interfere with the satellite signal. XXX---Insert graphic here?---XXX
IRIDIUM Getting Started
To connect to the TS-IRIDIUM modem hardware, configure the TS-IRIDIUM jumper configuration and load the serial port driver thus:
source /sbin/ts7800.subr pc104on modprobe ts7800_isa16550 irq=5 io=0x3f8
Once the driver has been loaded, a quick test of modem functionality can be achieved by using your choice of terminal emulator and querying the modem using some AT commands, for example:
root@ts7800-v2:~# picocom -b 19200 /dev/ttyS12 picocom v1.7 port is : /dev/ttyS12 flowcontrol : none baudrate is : 19200 parity is : none databits are : 8 escape is : C-a local echo is : no noinit is : no noreset is : no nolock is : no send_cmd is : sz -vv receive_cmd is : rz -vv imap is : omap is : emap is : crcrlf,delbs, Terminal ready at+gmm IRIDIUM 9600 Family SBD Transceiver OK at+gmr Call Processor Version: TA16005 Modem DSP Version: 1.7 svn: 2358 DBB Version: 0x0001 (ASIC) RFA Version: 0x0007 (SRFA2) NVM Version: KVS Hardware Version: BOOT07d2/9602NrvA-D/04/RAW0d BOOT Version: TA16005 (rev exported) OK
The modem's IMEI is available using at+gsn. This number identifies the modem on the satellite network and will be used both during setup with your satellite provider, and in sending/receiving data on the modem device.
