If the same receiver is used for both IP and Cellular, the information entered for the IP connection can be
quickly copied to the cellular settings.
Encryption
One of four different encryption levels can be selected. If appropriate the
key can also be set. The key is made up of Hex characters (0 to 9 and A to E)
and the length required depends on the level of encryption selected:
128 bit – 32 characters
192 bit – 48 characters
256 bit – 64 characters
Poll period and Reporting delay
The terminal has two polling periods:
Primary – this is equivalent to the Primary ATP as described in EN50136-1 The terminal uses one of its ARC
connections as the primary, starting with Main via IP and rotating to the others if a path is not operational in
the order of Backup via IP, Main via Cellular and Backup via Cellular.
Alternative – the connections not used as Primary.
Polling can be disabled by setting the period to 0.
When the terminal identifies a fault with a connection it waits for the time defined by the Reporting Delay
before reporting the fault to the ARC. This brings the reporting time in line with EN50136-1.
Suggested settings are shown in the Wizard DC-09 section earlier in this guide.
.
Account prefix
This is additional information that the terminal can send to the ARC that may
may be required by the ARC to uniquely identify the account.
Receiver number
This is also additional information that the terminal sends to the ARC that may
be required by the ARC to uniquely identify the account. This can also be left
blank unless specified by the ARC.
