OPERATIONS 4-7
O&M of the MCC-545B PACKET DATA RADIO

are sent only over the route where the shortest transmit queues exist. (MASTER
OPERATION ONLY)
INF – infinity hop quantity (default 8 hops). Defines the width of the network in hops
plus one to determine when connectivity to a node is broken. Should be as low as
possible to minimize auto-connectivity traffic in the network, but large enough to
not erroneously flag nodes as being offline. (MASTER OPERATION ONLY)
RELAY – relay function specification (default ON). Specifies whether the 545B should act
like a Remote in terms of relay functionality (i.e., does not share connectivity
table with other Masters. (MASTER OPERATION ONLY)
DATAP – priority of data reports initiated at the MCC-545B (default Y precedence). When
used in any data collection network, this setting defines the precedence of data
reports generated asynchronously by the equipment itself. Typically, it should be
lower than operator entered messages and commands.
MBHOP – meteor burst link hop weight (default 1 hop). Defines the number of network
hops to associate with a meteor burst Master Station link when determining the
minimum path to use in routing a message. Should be high enough to prevent a
meteor burst Master Station link to be picked over a line-of-sight Remote to
Remote link in a generally line-of-sight network.
4.2.4 Selecting the Burst Monitor
The 545B has a unique meteor burst monitor capability that allows you to monitor the number of
characters received, the RF signal level, and other parameters on each reception.
To turn on the burst monitor and record statistics on meteor bursts, 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 get some maintenance benefit from the monitor, enter:
MON,500,100
This limits the printout to meteors that have a duration character count greater than 500, or a
received character count greater than 100. You can adjust these parameters as desired.
