The GEM-100 expansion module is designed to interface to the SAT-201 satellite terminal to provide expanded interface capabilities and battery back-up. The GEM-100 and SAT-201 combination supersedes, and provides an alternative to, the SAT-101 terminal.
The GEM-100 offers like for like functionality and features that were so popular in the SAT-101, such as independent power management, which is a key feature for the security and oil and gas sectors. The GEM-100, when combined with the 1.7 Ah NiCad battery pack, provides backup power to both the GEM and the SAT-201, and is automatically charged through the GEM-100 when connected to a 9.6 to 30 volt DC source. The GEM-100 can also be connected directly to a suitable solar panel to provide external power.
The GEM-100 has four additional input/outputs to complement the four input/outputs of the SAT-201, allowing for more complex solutions to be implemented. The additional input/outputs are digital or analogue (4-20 mA current loop).
