First up is a common item which is how the device is wired, as the outputs are not “driven”, they are “relay” outputs. When the output is active, it sinks current to ground, and when not active, the pin is high Z (but not high voltage). To use the output pin as a high/low IE VCC/GND output, you would wire a pullup resistor on the output.
The MCG-101 works in the general range of WiFi, which is ~50 feet. The MCG-101 functions like a WiFi router at home. As long as the device is not in a bunker type building and as long as the antenna outside is unobstructed and in direct line of sight to the Iridium constellation, connectivity is possible within that give or take 50-foot radius to the device.
You must activate your SBD services first by contacting your Airtime service vendor and initiating activation. Once activated, you will be able to proceed with your configurations by following instructions in the Wiki: https://www.gsattrack.com/wiki/GSatMicro.ashx
First, be sure to generate the binary payload using the GSatMicroPublic C# library which generates the proper HMAC signing.
Make sure you also enter the actual IMEI of the device into this library for the correct HMAC key
For the command, make sure there is a “\r” on the end so it gets executed.
