ARLY-1 Cfg>NO CFG-PATTERN n MIP-PASSWORD password
h) CFG-PATTERN n RECEIVER-PASSWORD
Configures the password with which the VisorALARM encrypts its messages. This password can be
dependent on the mIP/IPDACT account number, in the same way as both the above.
Syntax:
ARLY-1 Cfg>CFG-PATTERN n RECEIVER-PASSWORD password
password Password of up to 16 hexadecimal digits (0 to 9, A, B, C, D, E and F).
This also admits U, V, W, X, Y, Z.
Example:
ARLY-1 Cfg>CFG-PATTERN 10 RECEIVER-PASSWORD 12XYZ00BZ
ARLY-1 Cfg>
To return to the default configuration for this parameter, use the following command:
ARLY-1 Cfg>NO CFG-PATTERN n RECEIVER-PASSWORD password
i) CFG-PATTERN n KEEP-ALIVE-TIMER
Configures the time interval used by the MIP to check connectivity with the VisorALARM. Each time
this timer times out, a keep-alive frame is sent to notify the VisorALARM that the connection is active
and waits for its response.
Normally the keep-alive interval in the alarms panel is high as this implies a telephone call, however,
in the case of the mIP/IPDACT, this cost is not as such as this is dealing with traffic which in all
likeliness is running over a flat rate connection. In addition a high value is not advisable in cases
where the mIP/IPDACT goes out to Internet through a router executing NAT, a problematic situation.
This is because traffic coming from the ARC towards the NIP reaches this thanks to the router
maintaining the input in the NAT table active during a period of time, the input being refreshed with
supervision traffic. If the supervision interval is greater than the residence time for the input in the
NAT table, communications from the ARC will not be possible. In cases of the TELDAT devices, this
is around 5 minutes. A low value has the problem that the traffic the VisorALARM must process is
high, the same as the bandwidth requirements. If ARC Internet access is ADSL, you need to consider
that the upstream channel is smaller than the downstream one and that supervision traffic returned to
the mIP/IPDACTs is slighter greater than the incoming.
The incoming traffic to the ARC is:

The minimum supervision time can be 1 second and a VisorALARM can have 3000 mIP/IPDACTs
registered that give an input traffic of 1,58 Mbps. The return traffic is approximately 6% greater.
Syntax:
ARLY-1 Cfg>CFG-PATTERN n KEEP-ALIVE-TIMER time
time Time in seconds between keep-alive frames. Admits values between 0
and 90.
