NOTE: THIS SECTION UNDER ACTIVE CONSTRUCTION. PLEASE PARDON THE DUST.

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,

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.
