3. Specify the node number of the I/O Slave Station to be monitored on the
Serial Master Station's node setting switch.
W NODE
X10 X1
Note The Serial Master Station node number is set to the maximum
number of I/O Slave Stations. When the maximum number of
nodes is set to a number higher that the number of nodes connect-
ed, however, the highest node number is not used. The communi-
cations partner for this node number does not exist, so no display
is shown on the RSSI. If the node number is changed to that of a
node that is actually connected, the RSSI display will indicate the
corresponding signal strength.
4. Check the strength of the received signal from the I/O Slave Station spec-
ified by the node setting switch. The strength is indicated using 10 levels
on the RSSI display.
