View the voltage and temperature status of actively connected Trimble reference station receivers at the Voltage / Temperature Info view. Four columns of the table refer to the current voltage source. They show for each connection the current voltage (Voltage), the voltage source (Source, either number of the external port or of the internal battery slot), and the relative value of the current voltage in percent of the maximum available voltage from that source (Status). For the current internal receiver temperature, see the Temperature column. The External Power / Internal Power columns refer to the current status of all possible power sources in absolute volt values. With receivers that are passively connected or cannot transmit their physical status, the status is Not available.
