11.2 Showing the Table of the Bridge
The dLAN 200 DSpro adapter contains a bridge that learns the MAC addresses
and ports of all incoming packets. To see the addresses learned by the bridge,
type "/b t t". The dLAN 200 DSpro adapter will report a table with three colons.
First colon is the MAC address, second colon is the port number and third colon
is the age of the learned address.
Concerning the port numbers, the correspondence is as follows:
11.3 Checking and Changing Gains
The AGC menu contains several commands related to the physical signal level.
The most useful command in this menu is the transmission gain control. When
two dLAN 200 DSpro adapters are very close, the transmitter may saturate the
receiver. In this case, you must change the transmission gain to 0 (default is 1).
To change the transmission gain, type "/a txg 0". If you are experiencing satu-
ration between any two dLAN 200 DSpro adapters, you must reduce the trans-
mission gain in both of them to obtain symmetrical behavior.
You can check the gains typing "i" at the AGC menu or the root menu.
11.4 Checking the Bits per Carrier
The quality of the channel is reflected in the number of bits per carrier (BPC) or
in its aggregate, the number of bits per symbol (BPS).
You can check the number of bits per carrier of any of the PLC ports (9 to 127)
in transmission and reception. For example, to check the BPCs in reception for
port 9, type "/bpc g rx 9". To check the BPCs in transmission for port 9, type "/
bpc g tx 9". The output of this command is a vector of numbers, each digit sho-
wing the number of bits assigned to one carrier. Values range from 2 to A (2 to
10).
