Page 53 MRC-565 Packet Data Radio Operations & Maintenance
Battery Voltage 0- 20VDC
Power Amplifier Uses a lookup table to relate the printed power levels to the VF voltage
Power Amplifier Uses a lookup table to relate the printed power levels to the VR voltage
Power Amplifier Temperature
Six Internal Regulated Voltages
Six External Voltages (ADC1 – ADC6)
Table 5.2-1 below lists the various parameters.
The MRC-565 automatically converters the raw readings from its A/D converter to calibrated
engineering units for operator use. The scale factor and offset values for the first ten parameter
are preset in the software and should not be changed. The final 6 parameters are external
parameters that are input through the I/O connector. (Refer to Section 4.4.1.4)
Entering the following command will produce a table of A/D readings along with their scale and
offset values as well as Raw and Cal values for each parameter
SCALE
16 parameters are read by the A/D converter as noted below.
