A4.2.3 Encryption
AES encryption, as defined in the DC-09 standard, can be configured as Encryption off, key length 128 bit,
192 bit or 256 bit. The key must be set up with the appropriate number of characters, depending on the
number of bits 128 bits = 32, 192 bits = 48, 256 bits = 64. Note that because of the length of the key, which
cannot be displayed completely on the Touch screen, using the IRIS Toolbox provides an easier method of
setting the key.
A4.2.4 Poll Period
The terminal expects the panel to communicate, either with an alarm or a "NULL" message at the rate
configured here. If the terminal does not see a message within the time specified it will report a Peripheral
Serial Interface fault.
A4.2.5 IP Port
This setting defines the IP port used for communications between the panel and the terminal, either using
TCP or UDP.
