Inquiry:GSatMicro OEM: Where is the command on how to set the relay output pins high or low on the GSatMicro OEM?
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.
