7.3 Connect to Site
Before SENTINEL can communicate with an RCU a communications connection must be established. This function
allows the operator to select a site for connection. By selecting a site name then pressing the connect button
SENTINEL will use the information in the Configuration database to determine the connection method and will
automatically connect to the selected site. ( see also Site General Configuration )
If the site name is not known or an RCU from a site is under going maintenance then by selecting *MANUAL* a
manual connection can be established.
Connection Type
This determines the method that SENTINEL will use to communicate with the RCU.
• Direct Connection This is for a 'simple' point to point hardwired serial connection.
• Radio Connection This utilises a simplex radio modem link as the communication medium.
• PSTN modem This requires an approved modem such as the Maestro Woomera modem configured for PSTN
dial up and uses either a PABX or PSTN dial up line connection as the communication medium.
• Leased Line This requires an approved modem such as the Maestro Woomera modem configured for either two
wire or four wire leased line connection as the communication medium.
• Mobile modem This requires an approved modem such as the Maestro Woomera modem configured for PSTN
dial up and uses a mobile phone dial up line connection as the communication medium.
Site Phone Number

number with 'T' if tone dialing is available.
