•The threshold that defines when data is missing from a certain

RTU. If no data is collected from a certain RTU for the

specified time interval (in seconds), the data from this RTU will

first be signalled in addVANTAGE as missing, then when (and

if) later retrieved, marked as being delayed (default 3600).

Note: This functionality is supported in addVANTAGE 3.4x only.

•The Modem combo-box defines what modem to use for

polling the A733GSM/GPRS stations. By default, the built-in

modem is used if it is installed. For gateways without internal

modem, the selection is restricted to the external modem.

•A poll schedule than can be used to poll the RTUs at certain

hours of the day (this functionality is displayed after clicking

the back arrow left of the Poll schedule message). You can

select poll times every half an hour. A dark button means that

a poll will be made at the specified time of the day. This is a

global parameter, however you can set a different poll

schedule for each individual RTU (see next section, “Adding

New RTUs” on page 38).
