The IOX-SATIRDv2 gives a Geotab GO device a backup path over the Iridium satellite network, so alerts, ignition changes and possible collisions still reach the office when the truck is out of cell range.

The IOX-SATIRDv2 is a two-part add-on: an IOX cable that plugs into the GO device, and a separate Iridium satellite modem with its own antenna. A GO device normally reports over cellular. When a vehicle drives beyond cell coverage, regular reporting stops until it comes back in range. The IOX-SATIRDv2 does not replace cellular tracking. It sends a short list of important events over satellite so the fleet is not completely blind during those gaps.
It also includes a two-wire lead for a driver alert button, which makes it a practical distress option for crews that work far from towers.
Oil, gas and mining service trucks spend long stretches on lease roads and remote sites without signal. Satellite ignition and collision logs give supervisors a way to know a truck is moving and whether something went wrong.
Forestry, pipeline and utility right-of-way crews often work alone in back country. The alert button gives a lone worker a way to call for help that does not depend on a phone signal.
Long-haul and rural delivery fleets crossing dead zones can use the out-of-coverage log and location poll to fill in where a truck was during a gap.
Agricultural and environmental field fleets can use movement-while-off reporting to catch equipment hauled away from remote fields.

Two steps happen before anyone touches the vehicle. The Iridium modem has to be activated at least 24 hours ahead through a support ticket that lists the GO serial and the modem IMEI, and the install itself must be done where there is good cellular coverage, with ignition cycled, before the vehicle heads into dead zones. On the truck, the IOX plugs into the GO device and is cable tied. The modem location is limited by how far the IOX lead reaches from the GO. The antenna wants a clear view of the sky; Geotab supplies a magnetic base for the roof and adhesive for a dash mount, and advises against mounting it under the dash. The antenna and IOX cable connect to the end of the modem with the status LEDs. If an alert button is used, an engine rule for the alert button diagnostic is created in MyGeotab, and a button press is the test that confirms the satellite link. Moving the modem to a new GO device later takes a pairing change ticket, and suspending the GO does not shut off the modem.
It fits fleets that regularly operate outside cellular coverage and need to know about emergencies, ignition and collisions during those stretches. It is not full satellite tracking; by default it sends events, not a continuous breadcrumb trail. A fleet that only needs a driver alert button and always works in cell range can use the IOX-ALERT instead. Satellite service terms and messaging costs are not covered in the install document, so we confirm those with you before anything is ordered.
Not continuously. By default it sends specific events and answers location polls. A periodic satellite location update, such as every 15 minutes, is listed among Geotab's advanced parameters.
Yes. With the IOX-AUXM daisy chained to the IOX-SATIRDv2 and a custom parameter applied while in coverage, an Aux 1 trigger can send its alert by satellite.
The modem stays tied to the old pairing until a pairing change ticket is filed with both serial numbers.
