OPERATIONS
Page 54 MRC-565 Packet Data Radio Operations & Maintenance
The input voltage at the I/O connector must not exceed 5.00 VDC. A 12 bit A/D converter is
used to convert the input voltage to a digital value from 0 to 4095. Scale Factor is set using the
following formula:
Scale Factor = (5.0/4095) *1/INPUT DIVIDER = .0012207 * 1/INPUT DIVIDER
Where the INPUT DIVIDER is the voltage attenuator at the ADC input required to keep the
maximum input voltage below 5.00 VDC
Use the following command to change scale and offset values for each of the external inputs:
SCALE,ADCn,SCALE,OFFSET
5.3.6 Selecting the Burst Monitor
The MRC-565 has a unique meteor burst monitoring capability that allows monitoring the
number of characters received, the RF signal level and other parameters on each reception.
To turn on the burst monitor and to record statistics on a meteor burst link, type:
MON{,d{,r}}
The two optional parameters are designed to limit the printout. The burst monitor generates two
or three lines of printout for every burst. This could conceivably create hundreds of pages of
printout a day in a network environment. The first parameter is the duration character count
limit. Only meteors lasting long enough to deliver "d" characters will be monitored. The second
parameter is the received character count limit; if at least "r" characters are received on the burst,
a monitor line will be generated. The default values are 100 for "d" and 1 for "r". For example, to
limit the printout, but still receive some maintenance benefit from the monitor, enter:
MON,500,100
This will limit the printout to meteors that have a duration character count greater than 500, or a
received character count greater than 100. These parameters may be adjusted as desired.
The command MONOFF turns off the burst monitor
5.3.7 Controlling the Hourly Statistics Report
By default, an hourly statistics report is generated on the maintenance terminal port on the hour.
This report consists of the same statistic reports generated by the BINS, MEM, and STAT
commands.
The hourly report can be disabled by entering the command:
