Analog Outputs
Two signals provide low power analog outputs. These outputs are generated from filtered
PWM signals and have about 1% ripple. The settling time (within 2% of final output) is about
30ms for a 0–10V step. The Analog Outputs are protected against shorts to B+ or B-.

Important Note: During a software download (FLASH), the DAC output voltages will float up
and can reach as high as 10volts. Make sure that your vehicle system is safe and can tolerate this
event.
Note: If the battery system droops below 20volts, the DAC outputs will not reach the 10 volt
output specification and will start dropping as the battery voltage drops below 20volts.
Power
These signals provide power for the various sensors and communication system that might be
connected to the 1310. The PWR signal is normally only used for powering the 1311 handheld
programmer or the 840 Spyglass gage, but can be used to power other small sensors or
electronics. These three power supply signals are current limited. The limited supply current
can be split between these power pins as long as the total does not exceed 200ma.
