170 DL-V3 User Manual Rev 3
C.12 PWRSTATUS Power and Status Settings Summary
The PWRSTATUS log contains a summary of power and status settings for the DL-V3.
Voltage fields are accurate to ±5 mV.
1. When an external source is present, the power supply is cut off when the available system
voltage is less than 9.0 V. Due to variances between units, and variance in voltage due to
temperature, the exact cutoff voltage may vary. The DL-V3 is operational at 9.0 V.
2. The power supply to the DL-V3 COM3 port refers to the power status to the Bluetooth
connection on the port. See additional comments in the comvout section on Page 87.
3. The DL-V3 contains a power regulator between the power connector on the front of the DL-
V3 and the internal OEMV-3 card. A power supply of +9 to +28 V DC can be applied to the
DL-V3 but before power reaches the OEMV-3 card, it is regulated, see Figure 38 below. The
RXHWLEVELS and EXTRXHWLEVELS logs output the post-regulated voltage for the
OEMV-3 card. The PWRSTATUS log outputs the voltage for the DL-V3 system.
