AT <command errors>
Replies with ERROR (Code 4)
Characters with <no AT command>
Modem will echo characters in data stream but will be ignored until a
second “AT” is seen at which time the modem closes the virtual connection.
Operation Notes When AT Commands are ON
• Radios will not poll with the embedded RTU simulator unless a
connection is established.
• Network-wide diagnostics are unaffected by the dialed unit connection
status.
• The use of the TransNET OT command (Output Trigger) can be of
benefit in some configurations. See “OT [ON, OFF]” on Page 37 for
configuration details.
9.4 Configuration Parameters for Store-and-Forward
Services
The installation and configuration of a radio network with an Extension using
SAF is straightforward with only a few unique parameters that need to be
considered and set at each unit.
In every network there can be only one Master station. It will serve as the sole
gateway to the outside world. The following three tables detail the parameters
that will need to be set on each type of radio in the network.
• Network Master Radio—Table 21 on Page 57
• Extension Radio(s)—Table 22 on Page 58
• Remote Radio(s)—Table 23 on Page 59
