use an R0 setting. If the mux is configured mainly
for interactive users, R0 is the best setting.
SB1,SB1.5, SB2 Stop Bits
The Stop Bit commands set the number of stop bits
used in asynchronous characters. The default
condition is one stop bit SB1. An SB1 command
sets one, an SB1.5 command sets 1.5, and an SB2
command sets two stop bits.
SN Source Node Number
This command is not necessary when a MultiMux
900 Series is connected to another MultiMux 900
Series. SN is necessary when an MMH904/
MMH908 is connected to a MultiMux 16 or
MultiMux32 model. The SN command specifies the
node number of the local node. This number is
determined by you and can be any decimal number
up to 255. It should be assigned when you are
designing your network and needs to be unique to
any other node in your network. Remember that the
node number selected will be used by other nodes
(using a DNxxx command) when accessing the
node. For example, if you assign124 as the SN of a
local node (SN124 command), accessing thatnode
from another node requires 124 in the other
nodesDestination Node's number command
(DN124).
WL5-8 Word Length Select
The Word Length Select commands set the word
length for asynchronous communications. The
selections available are 5, 6, 7, and 8 bits which
correspond to WL5 through WL8.
