SLC Passthru Communications 14-7
DH-485 with S:34/0=0 or for DF1 Full-duplex with S:34/5=1, then a ‘+’ sign
will appear to the left of the SLC 5/03 icon. Clicking on the ‘+’ sign will
expose a DH-485 or DF1 network underneath the SLC 5/03 icon. Clicking on
the ‘+’ sign to the left of the DH-485 or DF1 network will result in RSWho
browsing for nodes 0 to 31 on the DH-485 network or for node 1 on the DF1
network.
Refer to the steps on page 14-13 for browsing multiple nodes when channel 0
is configured for DF1 Half-duplex Master or DF1 Radio Modem.
