Design Guide for the Polycom SoundStructure C16, C12, C8, and SR12
A - 118
Description
This parameter returns the voltage (in Volts) of the ConferenceLink power
supply.
dev_volt_neg_15 -15 V Supply Voltage
Description
This parameter returns the voltage (in Volts) of the -15 V power supply.
dev_volt_phantom Phantom Power Supply Voltage
Description
This parameter returns the output voltage (in Volts) of the specified phantom
power supply. There is one phantom power supply for each bank of four
inputs. Thus, there are two banks on an 8x8, three banks on a 12x12, and four
banks on a 16x16. The voltage will be 0 for supplies that are not present on a
device. Index 1 corresponds to the phantom power supply on mic inputs 1-4,
index 2 corresponds to the phantom power supply on mic inputs 5-8, and so
on.
